III. Augustin's Part in the Controversy.
Both by nature and by grace, Augustin was formed to be the champion of truth in this controversy. Of a naturally philosophical temperament, he saw into the springs of life with a vividness of mental perception to which most men are strangers; and his own experiences in his long life of resistance to, and then of yielding to, the drawings of God's grace, gave him a clear apprehension of the great evangelic principle that God seeks men, not men God, such as no sophistry could cloud. However much his philosophy or theology might undergo change in other particulars, there was one conviction too deeply imprinted upon his heart ever to fade or alter,—the conviction of the ineffableness of God's grace. Grace,—man's absolute dependence on God as the source of all good,—this was the common, nay, the formative element, in all stages of his doctrinal development, which was marked only by the ever growing consistency with which he built his theology around this central principle. Already in 397,—the year after he became bishop,—we find him enunciating with admirable clearness all the essential elements of his teaching, as he afterwards opposed them to Pelagius.  It was inevitable, therefore, that although he was rejoiced when he heard, some years later, of the zealous labours of this pious monk in Rome towards stemming the tide of luxury and sin, and esteemed him for his devout life, and loved him for his Christian activity, he yet was deeply troubled when subsequent rumours reached him that he was "disputing against the grace of God." He tells us over and over again, that this was a thing no pious heart could endure; and we perceive that, from this moment, Augustin was only biding his time, and awaiting a fitting opportunity to join issue with the denier of the Holy of holies of his whole, I will not say theology merely, but life. "Although I was grieved by this," he says, "and it was told me by men whom I believed, I yet desired to have something of such sort from his own lips or in some book of his, so that, if I began to refute it, he would not be able to deny it."  Thus he actually excuses himself for not entering into the controversy earlier. When Pelagius came to Africa, then, it was almost as if he had deliberately sought his fate. But circumstances secured a lull before the storm. He visited Hippo; but Augustin was absent, although he did not fail to inform himself on his return that Pelagius while there had not been heard to say "anything at all of this kind." The controversy against the Donatists was now occupying all the energies of the African Church, and Augustin himself was a ruling spirit in the great conference now holding at Carthage with them. While there, he was so immersed in this business, that, although he once or twice saw the face of Pelagius, he had no conversation with him; and although his ears were wounded by a casual remark which he heard, to the effect "that infants were not baptized for remission of sins, but for consecration to Christ," he allowed himself to pass over the matter, "because there was no opportunity to contradict it, and those who said it were not such men as could cause him solicitude for their influence." 
It appears from these facts, given us by himself, that Augustin was not only ready for, but was looking for, the coming controversy. It can scarcely have been a surprise to him when Paulinus accused Coelestius (412); and, although he was not a member of the council which condemned him, it was inevitable that he should at once take the leading part in the consequent controversy. Coelestius and his friends did not silently submit to the judgment that had been passed upon their teaching: they could not openly propagate their heresy, but they were diligent in spreading their plaints privately and by subterraneous whispers among the people.  This was met by the Catholics in public sermons and familiar colloquies held everywhere. But this wise rule was observed,—to contend against the erroneous teachings, but to keep silence as to the teachers, that so (as Augustin explains  ) "the men might rather be brought to see and acknowledge their error through fear of ecclesiastical judgment than be punished by the actual judgment." Augustin was abundant in these oral labours; and many of his sermons directed against Pelagian error have come down to us, although it is often impossible to be sure as to their date. For one of them (170) he took his text from Philippians 3:6-16, "as touching the righteousness which is by the law blameless; howbeit what things were gain to me, those have I counted loss for Christ." He begins by asking how the apostle could count his blameless conversation according to the righteousness which is from the law as dung and loss, and then proceeds to explain the purpose for which the law was given, our state by nature and under law, and the kind of blamelessness that the law could produce, ending by showing that man can have no righteousness except from God, and no perfect righteousness except in heaven. Three others (174, 175, 176) had as their text 1 Timothy 1:15, 16, and developed its teaching, that the universal sin of the world and its helplessness in sin constituted the necessity of the incarnation; and especially that the necessity of Christ's grace for salvation was just as great for infants as for adults. Much is very forcibly said in these sermons which was afterwards incorporated in his treatises. "There was no reason," he insists, "for the coming of Christ the Lord except to save sinners. Take away diseases, take away wounds, and there is no reason for medicine. If the great Physician came from heaven, a great sick man was lying ill through the whole world. That sick man is the human race" (175, 1). "He who says, I am not a sinner,' or I was not,' is ungrateful to the Saviour. No one of men in that mass of mortals which flows down from Adam, no one at all of men is not sick: no one is healed without the grace of Christ. Why do you ask whether infants are sick from Adam? For they, too, are brought to the church; and, if they cannot run thither on their own feet, they run on the feet of others that they may be healed. Mother Church accommodates others' feet to them so that they may come, others' heart so that they may believe, others' tongue so that they may confess; and, since they are sick by another's sin, so when they are healed they are saved by another's confession in their behalf. Let, then, no one buzz strange doctrines to you. This the Church has always had, has always held; this she has received from the faith of the elders; this she will perseveringly guard until the end. Since the whole have no need of a physician, but only the sick, what need, then, has the infant of Christ, if he is not sick? If he is well, why does he seek the physician through those who love him? If, when infants are brought, they are said to have no sin of inheritance (peccatum propaginis) at all, and yet come to Christ, why is it not said in the church to those that bring them, take these innocents hence; the physician is not needed by the well, but by the sick; Christ came not to call the just, but sinners'? It never has been said, and it never will be said. Let each one therefore, brethren, speak for him who cannot speak for himself. It is much the custom to intrust the inheritance of orphans to the bishops; how much more the grace of infants! The bishop protects the orphan lest he should be oppressed by strangers, his parents being dead. Let him cry out more for the infant who, he fears, will be slain by his parents. Who comes to Christ has something in him to be healed; and he who has not, has no reason for seeking the physician. Let parents choose one of two things: let them either confess that there is sin to be healed in their infants, or let them cease bringing them to the physician. This is nothing else than to wish to bring a well person to the physician. Why do you bring him? To be baptized. Whom? The infant. To whom do you bring him? To Christ. To Him, of course, who came into the world? Certainly, he says. Why did He come into the world? To save sinners. Then he whom you bring has in him that which needs saving?"  So again: "He who says that the age of infancy does not need Jesus' salvation, says nothing else than that the Lord Christ is not Jesus to faithful infants; i.e., to infants baptized in Christ. For what is Jesus? Jesus means saviour. He is not Jesus to those whom He does not save, who do not need to be saved. Now, if your hearts can bear that Christ is not Jesus to any of the baptized, I do not know how you can be acknowledged to have sound faith. They are infants, but they are made members of Him. They are infants, but they receive His sacraments. They are infants, but they become partakers of His table, so that they may have life."  The preveniency of grace is explicitly asserted in these sermons. In one he says, "Zaccheus was seen, and saw; but unless he had been seen, he would not have seen. For whom He predestinated, them also He called.' In order that we may see, we are seen; that we may love, we are loved. My God, may His pity prevent me!'"  And in another, at more length: "His calling has preceded you, so that you may have a good will. Cry out, My God, let Thy mercy prevent me' (Psalm 58:11). That you may be, that you may feel, that you may hear, that you may consent, His mercy prevents you. It prevents you in all things; and do you too prevent His judgment in something. In what, do you say? In what? In confessing that you have all these things from God, whatever you have of good; and from yourself whatever you have of evil" (176, 5). "We owe therefore to Him that we are, that we are alive, that we understand: that we are men, that we live well, that we understand aright, we owe to Him. Nothing is ours except the sin that we have. For what have we that we did not receive?" (1 Corinthians 9:7) (176, 6).
It was not long, however, before the controversy was driven out of the region of sermons into that of regular treatises. The occasion for Augustin's first appearance in a written document bearing on the controversy, was given by certain questions which were sent to him for answer by "the tribune and notary" Marcellinus, with whom he had cemented his intimacy at Carthage, the previous year, when this notable official was presiding, by the emperor's orders, over the great conference of the catholics and Donatists. The mere fact that Marcellinus, still at Carthage, where Coelestius had been brought to trial, wrote to Augustin at Hippo for written answers to important questions connected with the Pelagian heresy, speaks volumes for the prominent position he had already assumed in the controversy. The questions that were sent, concerned the connection of death with sin, the transmission of sin, the possibility of a sinless life, and especially infants' need of baptism.  Augustin was immersed in abundant labours when they reached him:  but he could not resist this appeal, and that the less as the Pelagian controversy had already grown to a place of the first importance in his eyes. The result was his treatise, On the Merits and Remission of Sins and on the Baptism of Infants, consisting of two books, and written in 412. The first book of this work is an argument for original sin, drawn from the universal reign of death in the world (2-8), from the teaching of Romans 5:12-21 (9-20), and chiefly from the baptism of infants (21-70).  It opens by exploding the Pelagian contention that death is of nature, and Adam would have died even had he not sinned, by showing that the penalty threatened to Adam included physical death (Genesis 3:19), and that it is due to him that we all die (Romans 8:10, 11; 1 Corinthians 15:21) (2-8). Then the Pelagian assertion that we are injured in Adam's sin only by its bad example, which we imitate, not by any propagation from it, is tested by an exposition of Romans 5:12 sq. (9-20). And then the main subject of the book is reached, and the writer sharply presses the Pelagians with the universal and primeval fact of the baptism of infants, as a proof of original sin (21-70). He tracks out all their subterfuges,—showing the absurdity of the assertions that infants are baptized for the remission of sins that they have themselves committed since birth (22), or in order to obtain a higher stage of salvation (23-28), or because of sin committed in some previous state of existence (31-33). Then turning to the positive side, he shows at length that the Scriptures teach that Christ came to save sinners, that baptism is for the remission of sins, and that all that partake of it are confessedly sinners (34 sq.); then he points out that John 2:7, 8, on which the Pelagians relied, cannot be held to distinguish between ordinary salvation and a higher form, under the name of "the kingdom of God" (58 sq.); and he closes by showing that the very manner in which baptism was administered, with its exorcism and exsufflation, implied the infant to be a sinner (63), and by suggesting that the peculiar helplessness of infancy, so different not only from the earliest age of Adam, but also from that of many young animals, may possibly be itself penal (64-69). The second book treats, with similar fulness, the question of the perfection of human righteousness in this life. After an exordium which speaks of the will and its limitations, and of the need of God's assisting grace (1-6), the writer raises four questions. First, whether it may be said to be possible, by God's grace, for a man to attain a condition of entire sinlessness in this life (7). This he answers in the affirmative. Secondly, he asks, whether any one has ever done this, or may ever be expected to do it, and answers in the negative on the testimony of Scripture (8-25). Thirdly, he asks why not, and replies briefly because men are unwilling, explaining at length what he means by this (26-33). Finally, he inquires whether any man has ever existed, exists now, or will ever exist, entirely without sin,—this question differing from the second inasmuch as that asked after the attainment in this life of a state in which sinning should cease, while this seeks a man who has never been guilty of sin, implying the absence of original as well as of actual sin. After answering this in the negative (34), Augustin discusses anew the question of original sin. Here after expounding from the positive side (35-38) the condition of man in paradise, the nature of his probation, and of the fall and its effects both on him and his posterity, and the kind of redemption that has been provided in the incarnation, he proceeds to answer certain cavils (39 sq.), such as, "Why should children of baptized people need baptism?"—"How can a sin be remitted to the father and held against the child?"—"If physical death comes from Adam, ought we not to be released from it on believing in Christ?"—and concludes with an exhortation to hold fast to the exact truth, turning neither to the right nor left,—neither saying that we have no sin, nor surrendering ourselves to our sin (57 sq.).
After these books were completed, Augustin came into possession of Pelagius' Commentary on Paul's Epistles, which was written while he was living in Rome (before 410), and found it to contain some arguments that he had not treated,—such arguments, he tells us, as he had not imagined could be held by any one.  Unwilling to re-open his finished argument, he now began a long supplementary letter to Marcellinus, which he intended to serve as a third and concluding book to his work. He was some time in completing this letter. He had asked to have the former two books returned to him; and it is a curious indication of his overworked state of mind, that he forgot what he wanted with them:  he visited Carthage while the letter was in hand, and saw Marcellinus personally; and even after his return to Hippo, it dragged along, amid many distractions, slowly towards completion.  Meanwhile, a long letter was written to Honoratus, in which a section on the grace of the New Testament was incorporated. At length the promised supplement was completed. It was professedly a criticism of Pelagius' Commentary, and therefore naturally mentioned his name; but Augustin even goes out of his way to speak as highly of his opponent as he can,  —although it is apparent that his esteem is not very high for his strength of mind, and is even less high for the moral quality that led to his odd, oblique way of expressing his opinions. There is even a half sarcasm in the way he speaks of Pelagius' care and circumspection, which was certainly justified by the event. The letter opens by stating and criticising in a very acute and telling dialectic, the new arguments of Pelagius, which were such as the following: "If Adam's sin injured even those who do not sin, Christ's righteousness ought likewise to profit even those who do not believe" (2-4); "No man can transmit what he has not; and hence, if baptism cleanses from sin, the children of baptized parents ought to be free from sin;" "God remits one's own sins, and can scarcely, therefore, impute another's to us; and if the soul is created, it would certainly be unjust to impute Adam's alien sin to it" (5). The stress of the letter, however, is laid upon two contentions,—1. That whatever else may be ambiguous in the Scriptures, they are perfectly clear that no man can have eternal life except in Christ, who came to call sinners to repentance (7); and 2. That original sin in infants has always been, in the Church, one of the fixed facts, to be used as a basis of argument, in order to reach the truth in other matters, and has never itself been called in question before (10-14). At this point, the writer returns to the second and third of the new arguments of Pelagius mentioned above, and discusses them more fully (15-20), closing with a recapitulation of the three great points that had been raised; viz., that both death and sin are derived from Adam's sin by all his posterity; that infants need salvation, and hence baptism; and that no man ever attains in this life such a state of holiness that he cannot truly pray, "Forgive us our trespasses."
Augustin was now to learn that one service often entails another. Marcellinus wrote to say that he was puzzled by what had been said in the second book of this work, as to the possibility of man's attaining to sinlessness in this life, while yet it was asserted that no man ever had attained, or ever would attain, it. How, he asked, can that be said to be possible which is, and which will remain, unexampled? In reply, Augustin wrote, during this same year (412), and sent to his noble friend, another work, which he calls On the Spirit and the Letter, from the prominence which he gives in it to the words of 2 Corinthians 3:6.  He did not content himself with a simple, direct answer to Marcellinus' question, but goes at length into a profound disquisition into the roots of the doctrine, and thus gives us, not a mere explanation of a former contention, but a new treatise on a new subject,—the absolute necessity of the grace of God for any good living. He begins by explaining to Marcellinus that he has affirmed the possibility while denying the actuality of a sinless life, on the ground that all things are possible to God,—even the passage of a camel through the eye of a needle, which nevertheless has never occurred (1, 2). For, in speaking of man's perfection, we are speaking really of a work of God,—and one which is none the less His work because it is wrought through the instrumentality of man, and in the use of his free will. The Scriptures, indeed, teach that no man lives without sin, but this is only the proclamation of a matter of fact; and although it is thus contrary to fact and Scripture to assert that men may be found that live sinlessly, yet such an assertion would not be fatal heresy. What is unbearable, is that men should assert it to be possible for man, unaided by God, to attain this perfection. This is to speak against the grace of God: it is to put in man's power what is only possible to the almighty grace of God (3, 4). No doubt, even these men do not, in so many words, exclude the aid of grace in perfecting human life,—they affirm God's help; but they make it consist in His gift to man of a perfectly free will, and in His addition to this of commandments and teachings which make known to him what he is to seek and what to avoid, and so enable him to direct his free will to what is good. What, however, does such a "grace" amount to? (5). Man needs something more than to know the right way: he needs to love it, or he will not walk in it; and all mere teaching, which can do nothing more than bring us knowledge of what we ought to do, is but the letter that killeth. What we need is some inward, Spirit-given aid to the keeping of what by the law we know ought to be kept. Mere knowledge slays: while to lead a holy life is the gift of God,—not only because He has given us will, nor only because He has taught us the right way, but because by the Holy Spirit He sheds love abroad in the hearts of all those whom He has predestinated, and will call and justify and glorify (Romans 8:29, 30). To prove this, he states to be the object of the present treatise; and after investigating the meaning of 2 Corinthians 3:6, and showing that "the letter" there means the law as a system of precepts, which reveals sin rather than takes it away, points out the way rather than gives strength to walk in it, and therefore slays the soul by shutting it up under sin,—while "the Spirit" is God's Holy Ghost who is shed abroad in our hearts to give us strength to walk aright,—he undertakes to prove this position from the teachings of the Epistle to the Romans at large. This contention, it will be seen, cut at the very roots of Pelagianism: if all mere teaching slays the soul, as Paul asserts, then all that what they called "grace" could, when alone, do, was to destroy; and the upshot of "helping" man by simply giving him free will, and pointing out the way to him, would be the loss of the whole race. Not that the law is sin: Augustin teaches that it is holy and good, and God's instrument in salvation. Not that free will is done away: it is by free will that men are led into holiness. But the purpose of the law (he teaches) is to make men so feel their lost estate as to seek the help by which alone they may be saved; and will is only then liberated to do good when grace has made it free. "What the law of works enjoins by menace, that the law of faith secures by faith. What the law of works does is to say, Do what I command thee;' but by the law of faith we say to God, Give me what thou commandest.'"(22).  In the midst of this argument, Augustin is led to discuss the differentiating characteristics of the Old and New Testaments; and he expounds at length (33-42) the passage in Jeremiah 31:31-34, showing that, in the prophet's view, the difference between the two covenants is that in the Old, the law is an external thing written on stones; while in the New, it is written internally on the heart, so that men now wish to do what the law prescribes. This writing on the heart is nothing else, he explains, than the shedding abroad by the Holy Spirit of love in our hearts, so that we love God's will, and therefore freely do it. Towards the end of the treatise (50-61), he treats in an absorbingly interesting way of the mutual relations of free will, faith, and grace, contending that all co-exist without the voiding of any. It is by free will that we believe; but it is only as grace moves us, that we are able to use our free will for believing; and it is only after we are thus led by grace to believe, that we obtain all other goods. In prosecuting this analysis, Augustin is led to distinguish very sharply between the faculty and use of free will (58), as well as between ability and volition (53). Faith is an act of the man himself; but only as he is given the power from on high to will to believe, will he believe (57, 60).
By this work, Augustin completed, in his treatment of Pelagianism, the circle of that triad of doctrines which he himself looked upon as most endangered by this heresy,  —original sin, the imperfection of human righteousness, the necessity of grace. In his mind, the last was the kernel of the whole controversy; and this was a subject which he could never approach without some heightened fervour. This accounts for the great attractiveness of the present work,—through the whole fabric of which runs the golden thread of the praise of God's ineffable grace. In Canon Bright's opinion, it "perhaps, next to the Confessions,' tells us most of the thoughts of that rich, profound, and affectionate mind' on the soul's relations to its God." 
After the publication of these treatises, the controversy certainly did not lull; but it relapsed for nearly three years again, into less public courses. Meanwhile, Augustin was busy, among other most distracting cares (Ep.145, 1), still defending the grace of God, by letters and sermons. A fair illustration of his state of mind at this time, may be obtained from his letter to Anastasius (145), which assuredly must have been written soon after the treatise On the Spirit and the Letter. Throughout this letter, there are adumbrations of the same train of thought that filled this treatise; and there is one passage which may almost be taken as a summary of it. Augustin is so weary of the vexatious cares that filled his life, that he is ready to long for the everlasting rest, and yet bewails the weakness which allowed the sweetness of external things still to insinuate itself into his heart. Victory over, and emancipation from, this, he asserts, "cannot, without God's grace, be achieved by the human will, which is by no means to be called free so long as it is subject to enslaving lusts." Then he proceeds: "The law, therefore, by teaching and commanding what cannot be fulfilled without grace, demonstrates to man his weakness, in order that the weakness, thus proved, may resort to the Saviour, by whose healing the will may be able to do what it found impossible in its weakness. So, then, the law brings us to faith, faith obtains the Spirit in fuller measure, the Spirit sheds love abroad in us, and love fulfils the law. For this reason the law is called a schoolmaster, under whose threatening and severity whosoever shall call on the name of the Lord shall be delivered.' But how shall they call on Him in whom they have not believed?' Wherefore, that the letter without the Spirit may not kill, the life-giving Spirit is given to those that believe and call upon Him; but the love of God is poured out into our hearts by the Holy Spirit who is given to us, so that the words of the same apostle, Love is the fulfilling of the law,' may be realized. Thus the law is good to him that uses it lawfully; and he uses it lawfully, who, understanding wherefore it was given, betakes himself, under the pressure of its threatening, to liberating grace. Whoever ungratefully despises this grace by which the ungodly is justified, and trusts in his own strength for fulfilling the law, being ignorant of God's righteousness, and going about to establish his own righteousness, is not submitting himself to the righteousness of God; and therefore the law is made to him not a help to pardon, but the bond of guilt; not because the law is evil, but because sin,' as it is written, works death to such persons by that which is good.' For by the commandment, he sins more grievously, who, by the commandment, knows how evil are the sins which he commits." Although Augustin states clearly that this letter is written against those "who arrogate too much to the human will, imagining that, the law being given, the will is, of its own strength, sufficient to fulfil the law, though not assisted by any grace imparted by the Holy Ghost, in addition to instruction in the law,"—he refrains still from mentioning the names of the authors of this teaching, evidently out of a lingering tenderness in his treatment of them. This will help us to explain the courtesy of a note which he sent to Pelagius himself at about this time, in reply to a letter he had received some time before from him; of which Pelagius afterwards (at the Synod of Diospolis) made, to say the least of it, an ungenerous use. This note,  Augustin tells us, was written with "tempered praises" (wherefrom we see his lessening respect for the man), and so as to admonish Pelagius to think rightly concerning grace,—so far as could be done without raising the dregs of the controversy in a formal note. This he accomplished by praying from the Lord for him, those good things by which he might be good forever, and might live eternally with Him who is eternal; and by asking his prayers in return, that he, too, might be made by the Lord such as he seemed to suppose he already was. How Augustin could really intend these prayers to be understood as an admonition to Pelagius to look to God for what he was seeking to work out for himself, is fully illustrated by the closing words of this almost contemporary letter to Anastasius: "Pray, therefore, for us," he writes, "that we may be righteous,—an attainment wholly beyond a man's reach, unless he know righteousness, and be willing to practise it, but one which is immediately realized when he is perfectly willing; but this cannot be in him unless he is healed by the grace of the Spirit, and aided to be able." The point had already been made in the controversy, that, by the Pelagian doctrine, so much power was attributed to the human will, that no one ought to pray, "Lead us not into temptation, but deliver us from evil."
If he was anxious to avoid personal controversy with Pelagius himself in the hope that he might even yet be reclaimed, Augustin was equally anxious to teach the truth on all possible occasions. Pelagius had been intimate, when at Rome, with the pious Paulinus, bishop of Nola; and it was understood that there was some tendency at Nola to follow the new teachings. It was, perhaps, as late as 414, when Augustin made reply in a long letter,  to a request of Paulinus' for an exposition of certain difficult Scriptures, which had been sent him about 410.  Among them was Romans 11:28; and, in explaining it, Augustin did not withhold a tolerably complete account of his doctrine of predestination, involving the essence of his whole teaching as to grace: "For when he had said, according to the election they are beloved for their father's sake,' he added, for the gifts and calling of God are without repentance.' You see that those are certainly meant who belong to the number of the predestinated....Many indeed are called, but few chosen;' but those who are elect, these are called according to His purpose;' and it is beyond doubt that in them God's foreknowledge cannot be deceived. These He foreknew and predestinated to be conformed to the image of His Son, in order that He might be the first born among many brethren. But whom He predestinated, them He also called.' This calling is according to His purpose,' this calling is without repentance,'"etc., quoting Romans 5:28-31. Then continuing, he says, "Those are not in this vocation, who do not persevere unto the end in the faith that worketh by love, although they walk in it a little while....But the reason why some belong to it, and some do not, can easily be hidden, but cannot be unjust. For is there injustice with God? God forbid! For this belongs to those high judgments which, so to say, terrified the wondering apostle to look upon."
Among the most remarkable of the controversial sermons that were preached about this time, especial mention is due to two that were delivered at Carthage, midsummer of 413. The former of these  was preached on the festival of John the Baptist's birth (June 24), and naturally took the forerunner for its subject. The nativity of John suggesting the nativity of Christ, the preacher spoke of the marvel of the incarnation. He who was in the beginning, and was the Word of God, and was Himself God, and who made all things, and in whom was life, even this one "came to us. To whom? To the worthy? Nay, but to the unworthy! For Christ died for the ungodly, and for the unworthy, though He was worthy. We indeed were unworthy whom He pitied; but He was worthy who pitied us, to whom we say, For Thy pity's sake, Lord, free us!' Not for the sake of our preceding merits, but for Thy pity's sake, Lord, free us;' and for Thy name's sake be propitious to our sins,' not for our merit's sake....For the merit of sins is, of course, not reward, but punishment." He then dwelt upon the necessity of the incarnation, and the necessity of a mediator between God and "the whole mass of the human race alienated from Him by Adam." Then quoting 1 Corinthians 4:7, he asserts that it is not our varying merits, but God's grace alone, that makes us differ, and that we are all alike, great and small, old and young, saved by one and the same Saviour. "What then, some one says," he continues, "even the infant needs a liberator? Certainly he needs one. And the witness to it is the mother that faithfully runs to church with the child to be baptized. The witness is Mother Church herself, who receives the child for washing, and either for dismissing him [from this life] freed, or nurturing him in piety....Last of all, the tears of his own misery are witness in the child himself....Recognize the misery, extend the help. Let all put on bowels of mercy. By as much as they cannot speak for themselves, by so much more pityingly let us speak for the little ones,"—and then follows a passage calling on the Church to take the grace of infants in their charge as orphans committed to their care, which is in substance repeated from a former sermon.  The speaker proceeded to quote Matthew 1:21, and apply it. If Jesus came to save from sins, and infants are brought to Him, it is to confess that they, too, are sinners. Then, shall they be withheld from baptism? "Certainly, if the child could speak for himself, he would repel the voice of opposition, and cry out, Give me Christ's life! In Adam I:died: give me Christ's life; in whose sight I am not clean, even if I am an infant whose life has been but one day in the earth.'" "No way can be found," adds the preacher, "of coming into the life of this world except by Adam; no way can be found of escaping punishment in the next world except by Christ. Why do you shut up the one door?" Even John the Baptist himself was born in sin; and absolutely no one can be found who was born apart from sin, until you find one who was born apart from Adam. "By one man sin entered into the world, and by sin, death; and so it passed through upon all men.' If these were my words, could this sentiment be expressed more expressly, more clearly, more fully?"
Three days afterwards,  on the invitation of the Bishop of Carthage, Augustin preached a sermon professedly directed against the Pelagians,  which takes up the threads hinted at in the former discourse, and develops a full polemic with reference to the baptism of infants. He began, formally enough, with the determination of the question in dispute. The Pelagians concede that infants should be baptized. The only question is, for what are they baptized? We say that they would not otherwise have salvation and eternal life; but they say it is not for salvation, not for eternal life, but for the kingdom of God...."The child, they say, although not baptized, by the desert of his innocence, in that he has no sin at all, either actual or original, either from himself or contracted from Adam, necessarily has salvation and eternal life even if not baptized; but is to be baptized for this reason,—that he may enter into the kingdom of God, i.e., into the kingdom of heaven." He then shows that there is no eternal life outside the kingdom of heaven, no middle place between the right and left hand of the judge at the last day, and that, therefore, to exclude one from the kingdom of God is to consign him to the pains of eternal fire; while, on the other side, no one ascends into heaven unless he has been made a member of Christ, and this can only be by faith,—which, in an infant's case, is professed by another in his stead. He then treats, at length, some of the puzzling questions with which the Pelagians were wont to try the catholics; and then breaking off suddenly, he took a volume in his hands. "I ask you," he said, "to bear with me a little: I will read somewhat. It is St. Cyprian whom I hold in my hand, the ancient bishop of this see. What he thought of the baptism of infants,—nay, what he has shown that the Church always thought,—learn in brief. For it is not enough for them to dispute and argue, I know not what impious novelties: they even try to charge us with asserting something novel. It is on this account that I read here St. Cyprian, in order that you may perceive that the orthodox understanding and catholic sense reside in the words which I have been just now speaking to you. He was asked whether an infant ought to be baptized before he was eight days old, seeing that by the ancient law no infant was allowed to be circumcised unless he was eight days old. A question arose from this as to the day of baptism,—for concerning the origin of sin there was no question; and therefore from this thing of which there was no question, that question that had arisen was settled." And then he read to them the passage out of Cyprian's letter to Fidus, which declared that he, and all the council with him, unanimously thought that infants should be baptized at the earliest possible age, lest they should die in their inherited sin, and so pass into eternal punishment.  The sermon closed with a tender warning to the teachers of these strange doctrines: he might call them heretics with truth, but he will not; let the Church seek still their salvation, and not mourn them as dead; let them be exhorted as friends, not striven with as enemies. "They disparage us," he says, "we will bear it; let them not disparage the rule [of faith], let them not disparage the truth; let them not contradict the Church, which labours every day for the remission of infants' original sin. This thing is settled. The errant disputer may be borne with in other questions that have not been thoroughly canvassed, that are not yet settled by the full authority of the Church,—their error should be borne with: it ought not to extend so far, that they endeavour to shake even the very foundation of the Church!" He hints that although the patience hitherto exhibited towards them is "perhaps not blameworthy," yet patience may cease to be a virtue, and become culpable negligence: in the mean time, however, he begs that the catholics should continue amicable, fraternal, placid, loving, long suffering.
Augustin himself gives us a view of the progress of the controversy at this time in a letter written in 414.  The Pelagians had everywhere scattered the seeds of their new error; and although some, by his ministry and that of his brother workers, had, "by God's mercy," been cured of their pest, yet they still existed in Africa, especially about Carthage, and were everywhere propagating their opinions in subterraneous whispers, for fear of the judgment of the Church. Wherever they were not refuted, they were seducing others to their following; and they were so spread abroad that he did not know where they would break out next. Nevertheless, he was still unwilling to brand them as heretics, and was more desirous of healing them as sick members of the Church than of cutting them off finally as too diseased for cure. Jerome also tells us that the poison was spreading in both the East and the West, and mentions particularly as seats where it showed itself the islands of Rhodes and Sicily. Of Rhodes we know nothing further; but from Sicily an appeal came to Augustin in 414 from one Hilary,  setting forth that there were certain Christians about Syracuse who taught strange doctrines, and beseeching Augustin to help him in dealing with them. The doctrines were enumerated as follows: "They say (1) that man can be without sin, (2) and can easily keep the commandments of God if he will; (3) that an unbaptized infant, if he is cut off by death, cannot justly perish, since he is born without sin; (4) that a rich man that remains in his riches cannot enter the kingdom of God, except he sell all that he has;...(5) that we ought not to swear at all;" (6) and, apparently, that the Church is to be in this world without spot or blemish. Augustin suspected that these Sicilian disturbances were in some way the work of Coelestius, and therefore in his answer  informs his correspondent of what had been done at the Synod of Carthage (412) against him. The long letter that he sent back follows the inquiries in the order they were put by Hilary. To the first he replies, in substance, as he had treated the same matter in the second book of the treatise, On the Merits and Forgiveness of Sins, that it was opposed to Scripture, but was less a heresy than the wholly unbearable opinion that this state of sinlessness could be attained without God's help. "But when they say that free will suffices to man for fulfilling the precepts of the Lord, even though unaided to good works by God's grace and the gift of the Holy Spirit, it is to be altogether anathematized and detested with all execrations. For those who assert this are inwardly alien from God's grace, because being ignorant of God's righteousness, like the Jews of whom the apostle speaks, and wishing to establish their own, they are not subject to God's righteousness, since there is no fulfilment of the law except love; and of course the love of God is shed abroad in our hearts, not by ourselves, nor by the force of our own will, but by the Holy Ghost who is given to us." Dealing next with the second point, he drifts into the matter he had more fully developed in his work On the Spirit and the Letter. "Free will avails for God's works," he says, "if it be divinely aided, and this comes by humble seeking and doing; but when deserted by divine aid, no matter how excellent may be its knowledge of the law, it will by no means possess solidity of righteousness, but only the inflation of ungodly pride and deadly arrogance. This is taught us by that same Lord's Prayer; for it would be an empty thing for us to ask God Lead us not into temptation,' if the matter was so placed in our power that we would avail for fulfilling it without any aid from Him. For this free will is free in proportion as it is sound, but it is sound in proportion as it is subject to divine pity and grace. For it faithfully prays, saying, Direct my ways according to Thy word, and let no iniquity reign over me.' For how is that free over which iniquity reigns? But see who it is that is invoked by it, in order that it may not reign over it. For it says not, Direct my ways according to free will because no iniquity shall rule over me,' but Direct my ways according to Thy word, and let no iniquity rule over me.' It is a prayer, not a promise; it is a confession, not a profession; it is a wish for full freedom, not a boast of personal power. For it is not every one who confides in his own power,' but every one who calls on the name of God, that shall be saved.' But how shall they call upon Him,' he says, in whom they have not believed?' Accordingly, then, they who rightly believe, believe in order to call on Him in whom they have believed, and to avail for doing what they receive in the precepts of the law; since what the law commands, faith prays for." "God, therefore, commands continence, and gives continence; He commands by the law, He gives by grace; He commands by the letter, He gives by the spirit: for the law without grace makes the transgression to abound, and the letter without the spirit kills. He commands for this reason,—that we who have endeavoured to do what He commands, and are worn out in our weakness under the law, may know how to ask for the aid of grace; and if we have been able to do any good work, that we may not be ungrateful to Him who aids us." The answer to the third point traverses the ground that was fully covered in the first book of the treatise On the Merits and Forgiveness of Sins, beginning by opposing the Pelagians to Paul in Romans 5:12-19: "But when they say that an infant, cut off by death, unbaptized, cannot perish since he is born without sin,—it is not this that the apostle says; and I think that it is better to believe the apostle than them." The fourth and fifth questions were new in this controversy; and it is not certain that they belong properly to it, though the legalistic asceticism of the Pelagian leaders may well have given rise to a demand on all Christians to sell what they had, and give to the poor. This one of the points, Augustin treats at length, pointing out that many of the saints of old were rich, and that the Lord and His apostles always so speak that their counsels avail to the right use, not the destruction, of wealth. Christians ought so to hold their wealth that they are not held by it, and by no means prefer it to Christ. Equal good sense and mildness are shown in his treatment of the question concerning oaths, which he points out were used by the Lord and His apostles, but advises to be used as little as possible lest by the custom of frequent oaths we learn to swear lightly. The question as to the Church, he passes over as having been sufficiently treated in the course of his previous remarks.
To the number of those who had been rescued from Pelagianism by his efforts, Augustin was now to have the pleasure of adding two others, in whom he seems to have taken much delight. Timasius and James were two young men of honorable birth and liberal education, who had, by the exhortation of Pelagius, been moved to give up the hope that they had in this world, and enter upon the service of God in an ascetic life.  Naturally, they had turned to him for instruction, and had received a book to which they had given their study. They met somewhere with some of Augustin's writings, however, and were deeply affected by what he said as to grace, and now began to see that the teaching of Pelagius opposed the grace of God by which man becomes a Christian. They gave their book, therefore, to Augustin, saying that it was Pelagius', and asking him for Pelagius' sake, and for the sake of the truth, to answer it. This was done, and the resulting book, On Nature and Grace, sent to the young men, who returned a letter of thanks  in which they professed their conversion from their error. In this book, too, which was written in 415, Augustin refrained from mentioning Pelagius by name,  feeling it better to spare the man while not sparing his writings. But he tells us, that, on reading the book of Pelagius to which it was an answer, it became clear to him beyond any doubt that his teaching was distinctly anti-Christian;  and when speaking of his own book privately to a friend, he allows himself to call it "a considerable book against the heresy of Pelagius, which he had been constrained to write by some brethren whom he had persuaded to adopt his fatal error, denying the grace of Christ."  Thus his attitude towards the persons of the new teachers was becoming ever more and more strained, in despite of his full recognition of the excellent motives that might lie behind their "zeal not according to knowledge." This treatise opens with a recognition of the zeal of Pelagius, which, as it burns most ardently against those who, when reproved for sin, take refuge in censuring their nature, Augustin compares with the heathen view as expressed in Sallust's saying, "the human race falsely complains of its own nature,"  and which he charges with not being according to knowledge, and proposes to oppose by an equal zeal against all attempts to render the cross of Christ of none effect. He then gives a brief but excellent summary of the more important features of the catholic doctrine concerning nature and grace (2-7). Opening the work of Pelagius, which had been placed in his hands, he examines his doctrine of sin, its nature and effects. Pelagius, he points out, draws a distinction, sound enough in itself, between what is "possible" and what is "actual," but applies it unsoundly to sin, when he says that every man has the possibility of being without sin (8-9), and therefore without condemnation. Not so, says Augustin; an infant who dies unbaptized has no possibility of salvation open to him; and the man who has lived and died in a land where it was impossible for him to hear the name of Christ, has had no possibility open to him of becoming righteous by nature and free will. If this be not so, Christ is dead in vain, since all men then might have accomplished their salvation, even if Christ had never died (10). Pelagius, moreover, he shows, exhibits a tendency to deny the sinful character of all sins that are impossible to avoid, and so treats of sins of ignorance as to show that he excuses them (13-19). When he argues that no sin, because it is not a substance, can change nature, which is a substance, Augustin replies that this destroys the Saviour's work,—for how can He save from sins if sins do not corrupt? And, again, if an act cannot injure a substance, how can abstention from food, which is a mere act, kill the body? In the same way sin is not a substance; but God is a substance,—yea, the height of substance, and only true sustenance of the reasonable creature; and the consequence of departure from Him is to the soul what refusal of food is to the body (22). To Pelagius' assertion that sin cannot be punished by more sin, Augustin replies that the apostle thinks differently (Romans 1:21-31). Then putting his finger on the main point in controversy, he quotes the Scriptures as declaring the present condition of man to be that of spiritual death. "The truth then designates as dead those whom this man declares to be unable to be damaged or corrupted by sin,—because, forsooth, he has discovered sin to be no substance!" (25). It was by free will that man passed into this state of death; but a dead man needs something else to revive him,—he needs nothing less than a Vivifier. But of vivifying grace, Pelagius knew nothing; and by knowing nothing of a Vivifier, he knows nothing of a Saviour; but rather by making nature of itself able to be sinless, he glorifies the Creator at the expense of the Saviour (39). Next is examined Pelagius' contention that many saints are enumerated in the Scriptures as having lived sinlessly in this world. While declining to discuss the question of fact as to the Virgin Mary (42), Augustin opposes to the rest the declaration of John in 1 John 1:8, as final, but still pauses to explain why the Scriptures do not mention the sins of all, and to contend that all who ever were saved under the Old Testament or the New, were saved by the sacrificial death of Christ, and by faith in Him (40-50). Thus we are brought, as Augustin says, to the core of the question, which concerns, not the fact of sinlessness in any man, but man's ability to be sinless. This ability Pelagius affirms of all men, and Augustin denies of all "unless they are justified by the grace of God through our Lord Jesus Christ and Him crucified" (51). Thus, the whole discussion is about grace, which Pelagius does not admit in any true sense, but places only in the nature that God has made (52). We are next invited to attend to another distinction of Pelagius', in which he discriminates sharply between the nature that God has made, the crown of which is free will, and the use that man makes of this free will. The endowment of free will is a "capacity;" it is, because given by God in our making, a necessity of nature, and not in man's power to have or not have. It is the right use of it only, which man has in his power. This analysis, Pelagius illustrates at length, by appealing to the difference between the possession and use of the various bodily senses. The ability to see, for instance, he says, is a necessity of our nature; we do not make it, we cannot help having it; it is ours only to use it. Augustin criticises this presentation of the matter with great sharpness (although he is not averse to the analysis itself),—showing the inapplicability of the illustrations used,—for, he asks, is it not possible for us to blind ourselves, and so no longer have the ability to see? and would not many a man like to control the "use" of his "capacity" to hear when a screechy saw is in the neighbourhood? (55); and as well the falsity of the contention illustrated, since Pelagius has ignored the fall, and, even were that not so, has so ignored the need of God's aid for all good, in any state of being, as to deny it (56). Moreover, it is altogether a fallacy, Augustin argues, to contend that men have the "ability" to make every use we can conceive of our faculties. We cannot wish for unhappiness; God cannot deny Himself (57); and just so, in a corrupt nature, the mere possession of a faculty of choice does not imply the ability to use that faculty for not sinning. "Of a man, indeed, who has his legs strong and sound, it may be said admissibly enough, whether he will or not, he has the capacity of walking;' but if his legs be broken, however much he may wish, he has not the capacity.' The nature of which our author speaks is corrupted" (57). What, then, can he mean by saying that, whether we will or not, we have the capacity of not sinning,—a statement so opposite to Paul's in Romans 7:15? Some space is next given to an attempted rebuttal by Pelagius of the testimony of Galatians 5:17, on the ground that the "flesh" there does not refer to the baptized (60-70); and then the passages are examined which Pelagius had quoted against Augustin out of earlier writers,—Lactantius (71), Hilary (72), Ambrose (75), John of Constantinople (76), Xystus,—a blunder of Pelagius, who quoted from a Pythagorean philosopher, mistaking him for the Roman bishop Sixtus (57), Jerome (78), and Augustin himself (80). All these writers, Augustin shows, admitted the universal sinfulness of man,—and especially he himself had confessed the necessity of grace in the immediate context of the passage quoted by Pelagius. The treatise closes (82 sq.) with a noble panegyric on that love which God sheds abroad in the heart, by the Holy Ghost, and by which alone we can be made keepers of the law.
The treatise On Nature and Grace was as yet unfinished, when the over-busy  scriptorium at Hippo was invaded by another young man seeking instruction. This time it was a zealous young presbyter from the remotest part of Spain, "from the shore of the ocean,"—Paulus Orosius by name, whose pious soul had been afflicted with grievous wounds by the Priscillianist and Origenist heresies that had broken out in his country, and who had come with eager haste to Augustin, on hearing that he could get from him the instruction which he needed for confuting them. Augustin seems to have given him his heart at once; and, feeling too little informed as to the special heresies which he wished to be prepared to controvert, persuaded him to go on to Palestine to be taught by Jerome, and gave him introductions which described him as one "who is in the bond of catholic peace a brother, in point of age a son, and in honour a fellow-presbyter,—a man of quick understanding, ready speech, and burning zeal." His departure to Palestine gave Augustin an opportunity to consult with Jerome on the one point that had been raised in the Pelagian controversy on which he had not been able to see light. The Pelagians had early argued,  that, if souls are created anew for men at their birth, it would be unjust in God to impute Adam's sin to them. And Augustin found himself unable either to prove that souls are transmitted (traduced, as the phrase is), or to show that it would not involve God in injustice to make a soul only to make it subject to a sin committed by another. Jerome had already put himself on record as a believer in both original sin and the creation of souls at the time of birth. Augustin feared the logical consequences of this assertion, and yet was unable to refute it. He therefore seized this occasion to send a long treatise on the origin of the soul to his friend, with the request that he would consider the subject anew, and answer his doubts.  In this treatise he stated that he was fully persuaded that the soul had fallen into sin, but by no fault of God or of nature, but of its own free will; and asked when could the soul of an infant have contracted the guilt, which, unless the grace of Christ should come to its rescue by baptism, would involve it in condemnation, if God (as Jerome held, and as he was willing to hold with him, if this difficulty could be cleared up) makes each soul for each individual at the time of birth? He professed himself embarrassed on sucha supposition by the penal sufferings of infants, the pains they endured in this life, and much more the danger they are in of eternal damnation, into which they actually go unless saved by baptism. God is good, just, omnipotent: how, then, can we account for the fact that "in Adam all die," if souls are created afresh for each birth? "If new souls are made for men," he affirms, "individually at their birth, I do not see, on the one hand, that they could have any sin while yet in infancy; nor do I believe, on the other hand, that God condemns any soul which He sees to have no sin;" "and yet, whoever says that those children who depart out of this life without partaking of the sacrament of baptism, shall be made alive in Christ, certainly contradicts the apostolic declaration," and "he that is not made alive in Christ must necessarily remain under the condemnation of which the apostle says that by the offence of one, judgment came upon all men to condemnation." "Wherefore," he adds to his correspondent, "if that opinion of yours does not contradict this firmly grounded article of faith, let it be mine also; but if it does, let it no longer be yours."  So far as obtaining light was concerned, Augustin might have spared himself the pain of this composition: Jerome simply answered  that he had no leisure to reply to the questions submitted to him. But Orosius' mission to Palestine was big with consequences. Once there, he became the accuser of Pelagius before John of Jerusalem, and the occasion, at least, of the trials of Pelagius in Palestine during the summer and winter of 415 which issued so disastrously, and ushered in a new phase of the conflict.
Meanwhile, however, Augustin was ignorant of what was going on in the East, and had his mind directed again to Sicily. About a year had passed since he had sent thither his long letter to Hilary. Now his conjecture that Coelestius was in some way at the bottom of the Sicilian outbreak, received confirmation from a paper which certain catholic brethren brought out of Sicily, and which was handed to Augustin by two exiled Spanish bishops, Eutropius and Paul. This paper bore the title, Definitions Ascribed to Coelestius, and presented internal evidence, in style and thought, of being correctly so ascribed.  It consisted of three parts, in the first of which were collected a series of brief and compressed "definitions," or "ratiocinations" as Augustin calls them, in which the author tries to place the catholics in a logical dilemma, and to force them to admit that man can live in this world without sin. In the second part, he adduced certain passages of Scripture in defence of his doctrine. In the third part, he undertook to deal with the texts that had been quoted against his contention, not, however, by examining into their meaning, or seeking to explain them in the sense of his theory, but simply by matching them with others which he thought made for him. Augustin at once (about the end of 415) wrote a treatise in answer to this, which bears the title of On the Perfection of Man's Righteousness. The distribution of the matter in this work follows that of the treatise to which it is an answer. First of all (1-16), the "ratiocinations" are taken up one by one and briefly answered. As they all concern sin, and have for their object to prove that man cannot be accounted a sinner unless he is able, in his own power, wholly to avoid sin,—that is, to prove that a plenary natural ability is the necessary basis of responsibility,—Augustin argues per contra that man can entail a sinfulness on himself for which and for the deeds of which he remains responsible, though he is no longer able to avoid sin; thus admitting that for the race, plenary ability must stand at the root of sinfulness. Next (17-22) he discusses the passages which Coelestius had advanced in defence of his teachings, viz., (1) passages in which God commands men to be without sin, which Augustin meets by saying that the point is, whether these commands are to be fulfilled without God's aid, in the body of this death, while absent from the Lord (17-20); and (2) passages in which God declares that His commandments are not grievous, which Augustin meets by explaining that all God's commandments are fulfilled only by Love, which finds nothing grievous; and that this love is shed abroad in our hearts by the Holy Ghost, without whom we have only fear, to which the commandments are not only grievous, but impossible. Lastly, Augustin patiently follows Coelestius through his odd "oppositions of texts," explaining carefully all that he had adduced, in an orthodox sense (23-42). In closing, he takes up Coelestius' statement, that "it is quite possible for man not to sin even in word, if God so will," pointing out how he avoids saying "if God give him His help," and then proceeds to distinguish carefully between the differing assertions of sinlessness that may be made. To say that any man ever lived, or will live, without needing forgiveness, is to contradict Romans 5:12, and must imply that he does not need a Saviour, against Matthew 9:12, 13. To say that after his sins have been forgiven, any one has ever remained without sin, contradicts 1 John 1:8 and Matthew 6:12. Yet, if God's help be allowed, this contention is not so wicked as the other; and the great heresy is to deny the necessity of God's constant grace, for which we pray when we say, "Lead us not into temptation."
Tidings were now (416) beginning to reach Africa of what was doing in the East. There was diligently circulated everywhere, and came into Augustin's hands, an epistle of Pelagius' own "filled with vanity," in which he boasted that fourteen bishops had approved his assertion that "man can live without sin, and easily keep the commandments if he wishes," and had thus "shut the mouth of opposition in confusion," and "broken up the whole band of wicked conspirators against him." Soon afterwards a copy of an "apologetical paper," in which Pelagius used the authority of the Palestinian bishops against his adversaries, not altogether without disingenuousness, was sent by him to Augustin through the hands of a common acquaintance, Charus by name. It was not accompanied, however, by any letter from Pelagius; and Augustin wisely refrained from making public use of it. Towards midsummer Orosius came with more authentic information, and bearing letters from Jerome and Heros and Lazarus. It was apparently before his coming that a controversial sermon was preached, only a fragment of which has come down to us.  So far as we can learn from the extant part, its subject seems to have been the relation of prayer to Pelagianism; and what we have, opens with a striking anecdote: "When these two petitions—Forgive us our debts as we also forgive our debtors,' and Lead us not into temptation'—are objected to the Pelagians, what do you think they reply? I was horrified, my brethren, when I heard it. I did not, indeed, hear it with my own ears; but my holy brother and fellow-bishop Urbanus, who used to be presbyter here, and now is bishop of Sicca," when he was in Rome, and was arguing with one who held these opinions, pressed him with the weight of the Lord's Prayer, and "what do you think he replied to him? We ask God,' he said, not to lead us into temptation, lest we should suffer something that is not in our power,—lest I should be thrown from my horse; lest I should break my leg; lest a robber should slay me, and the like. For these things,' he said, are not in my power; but for overcoming the temptations of my sins, I both have ability if I wish to use it, and am not able to receive God's help.'  You see, brethren," the good bishop adds, "how malignant this heresy is: you see how it horrifies all of you. Have a care that you be not taken by it." He then presses the general doctrine of prayer as proving that all good things come from God, whose aid is always necessary to us, and is always attainable by prayer; and closes as follows: "Consider, then, these things, my brethren, when any one comes to you and says to you, What, then, are we to do if we have nothing in our power, unless God gives all things? God will not then crown us, but He will crown Himself.' You already see that this comes from that vein: it is a vein, but it has poison in it; it is stricken by the serpent; it is not sound. For what Satan is doing to-day is seeking to cast out from the Church by the poison of heretics, just as he once cast out from Paradise by the poison of the serpent. Let no one tell you that this one was acquitted by the bishops: there was an acquittal, but it was his confession, so to speak, his amendment, that was acquitted. For what he said before the bishops seemed catholic; but what he wrote in his books, the bishops who pronounced the acquittal were ignorant of. And perchance he was really convinced and amended. For we ought not to despair of the man who perchance preferred to be united to the catholic faith, and fled to its grace and aid. Perchance this was what happened. But, in any event, it was not the heresy that was acquitted, but the man who denied the heresy." 
The coming of Orosius must have dispelled any lingering hope that the meaning of the council's finding was that Pelagius had really recanted. Councils were immediately assembled at Carthage and Mileve, and the documents which Orosius had brought were read before them. We know nothing of their proceedings except what we can gather from the letters which they sent  to Innocent at Rome, seeking his aid in their condemnation of the heresy now so nearly approved in Palestine. To these two official letters, Augustin, in company with four other bishops, added a third private letter,  in which they took care that Innocent should be informed on all the points necessary to his decision. This important letter begins almost abruptly with a characterization of Pelagianism as inimical to the grace of God, and has grace for its subject throughout. It accounts for the action of the Palestinian synod, as growing out of a misunderstanding of Pelagius' words, in which he seemed to acknowledge grace, which these catholic bishops understood naturally to mean that grace of which they read in the Scriptures, and which they were accustomed to preach to their people,—the grace by which we are justified from iniquity, and saved from weakness; while he meant nothing more than that by which we are given free will at our creation. "For if these bishops had understood that he meant only that grace which we have in common with the ungodly and with all, along with whom we are men, while he denied that by which we are Christians and the sons of God, they not only could not have patiently listened to him,—they could not even have borne him before their eyes." The letter then proceeds to point out the difference between grace and natural gifts, and between grace and the law, and to trace out Pelagius' meaning when he speaks of grace, and when he contends that man can be sinless without any really inward aid. It suggests that Pelagius be sent for, and thoroughly examined by Innocent, or that he should be examined by letter or in his writings; and that he be not cleared until he unequivocally confessed the grace of God in the catholic sense, and anathematized the false teachings in the books attributed to him. The book of Pelagius which was answered in the treatise On Nature and Grace was enclosed, with this letter, with the most important passages marked: and it was suggested that more was involved in the matter than the fate of one single man, Pelagius, who, perhaps, was already brought to a better mind; the fate of multitudes already led astray, or yet to be deceived by these false views, was in danger.
At about this same time (417), the tireless bishop sent a short letter  to a Hilary, who seems to be Hilary of Norbonne, which is interesting from its undertaking to convey a characterization of Pelagianism to one who was as yet ignorant of it. It thus brings out what Augustin conceived to be its essential features. "An effort has been made," we read, "to raise a certain new heresy, inimical to the grace of Christ, against the Church of Christ. It is not yet openly separated from the Church. It is the heresy of men who dare to attribute so much power to human weakness that they contend that this only belongs to God's grace,—that we are created with free will and the possibility of not sinning, and that we receive God's commandments which are to be fulfilled by us; but, for keeping and fulfilling these commandments, we do not need any divine aid. No doubt, the remission of sins is necessary for us; for we have no power to right what we have done wrong in the past. But for avoiding and overcoming sins in the future, for conquering all temptations with virtue, the human will is sufficient by its natural capacity without any aid of God's grace. And neither do infants need the grace of the Saviour, so as to be liberated by it through His baptism from perdition, seeing that they have contracted no contagion of damnation from Adam."  He engages Hilary in the destruction of this heresy, which ought to be "concordantly condemned and anathematized by all who have hope in Christ," as a "pestiferous impiety," and excuses himself for not undertaking its full refutation in a brief letter. A much more important letter was sent off, at about the same time, to John of Jerusalem, who had conducted the first Palestinian examination of Pelagius, and had borne a prominent part in the synod at Diospolis. He sent with it a copy of Pelagius' book which he had examined in his treatise On Nature and Grace, as well as a copy of that reply itself, and asked John to send him an authentic copy of the proceedings at Diospolis. He took this occasion seriously to warn his brother bishop against the wiles of Pelagius, and begged him, if he loved Pelagius, to let men see that he did not so love him as to be deceived by him. He pointed out that in the book sent with the letter, Pelagius called nothing the grace of God except nature; and that he affirmed, and even vehemently contended, that by free will alone, human nature was able to suffice for itself for working righteousness and keeping all God's commandments; whence any one could see that he opposed the grace of God of which the apostles spoke in Romans 7:24, 25, and contradicted, as well, all the prayers and benedictions of the Church by which blessings were sought for men from God's grace. "If you love Pelagius, then," he continued, "let him, too, love you as himself,—nay, more than himself; and let him not deceive you. For when you hear him confess the grace of God and the aid of God, you think he means what you mean by it. But let him be openly asked whether he desires that we should pray God that we sin not; whether he proclaims the assisting grace of God, without which we would do much evil; whether he believes that even children who have not yet been able to do good or evil are nevertheless, on account of one man by whom sin entered into the world, sinners in him, and in need of being delivered by the grace of Christ." If he openly denies such things, Augustin would be pleased to hear of it.
Thus we see the great bishop sitting in his library at Hippo, placing his hands on the two ends of the world. That nothing may be lacking to the picture of his universal activity, we have another letter from him, coming from about this same time, that exhibits his care for the individuals who had placed themselves in some sort under his tutelage. Among the refugees from Rome in the terrible times when Alaric was a second time threatening the city, was a family of noble women,—Proba, Juliana, and Demetrias,  —grandmother, mother, and daughter,—who, finding an asylum in Africa, gave themselves to God's service, and sought the friendship and counsel of Augustin. In 413 the granddaughter "took the veil" under circumstances that thrilled the Christian world, and brought out letters of congratulation and advice from Augustin and Jerome, and also from Pelagius. This letter of Pelagius seems not to have fallen into Augustin's way until now (416): he was so disturbed by it that he wrote to Juliana a long letter warning her against its evil counsels.  It was so shrewdly phrased, that, at first sight, Augustin was himself almost persuaded that it did somehow acknowledge the grace of God; but when he compared it with others of Pelagius' writings, he saw that here, too, he was using ambiguous phrases in a non-natural sense. The object of his letter (in which Alypius is conjoined, as joint author) to Juliana is to warn her and her holy daughter against all opinions that opposed the grace of God, and especially against the covert teaching of the letter of Pelagius to Demetrias.  "In this book," he says, "were it lawful for such an one to read it, a virgin of Christ would read that her holiness and all her spiritual riches are to spring from no other source than herself; and thus before she attains to the perfection of blessedness, she would learn—which may God forbid!—to be ungrateful to God." Then, after quoting the words of Pelagius, in which he declares that "earthly riches came from others, but your spiritual riches no one can have conferred on you but yourself; for these, then, you are justly praised, for these you are deservedly to be preferred to others,—for they can exist only from yourself and in yourself," he continues: "Far be it from any virgin to listen to statements like these. Every virgin of Christ understands the innate poverty of the human heart, and therefore declines to be adorned otherwise than by the gifts of her spouse....Let her not listen to him who says, No one can confer them on you but yourself, and they cannot exist except from you and in you:' but to him who says, We have this treasure in earthen vessels, that the excellency of the power may be of God, and not of us.' And be not surprised that we speak of these things as yours, and not from you; for we speak of daily bread as ours,' but yet add give it to us,' lest it should be thought it was from ourselves." Again, he warns her that grace is not mere knowledge any more than mere nature; and that Pelagius, even when using the word "grace," means no inward or efficient aid, but mere nature or knowledge or forgiveness of past sins; and beseeches her not to forget the God of all grace from whom (Wisdom i.20, 21) Demetrias had that very virgin continence which was so justly her boast.
With the opening of 417, came the answers from Innocent to the African letters.  And although they were marred by much boastful language concerning the dignity of his see, which could not but be distasteful to the Africans, they admirably served their purpose in the satisfactory manner in which they, on the one hand, asserted the necessity of the "daily grace, and help of God," for our good living, and, on the other, determined that the Pelagians had denied this grace, and declared their leaders Pelagius and Coelestius deprived of the communion of the Church until they should "recover their senses from the wiles of the Devil by whom they are held captive according to his will." Augustin may be pardoned for supposing that a condemnation pronounced by two provincial synods in Africa, and heartily concurred in by the Roman bishop, who had already at Jerusalem been recognized as in some sort the fit arbiter of this Western dispute, should settle the matter. If Pelagius had been before jubilant, Augustin found this a suitable time for his rejoicing.
About the same time with Innocent's letters, the official proceedings of the synod of Diospolis at last reached Africa, and Augustin lost no time (early in 417) in publishing a full account and examination of them, thus providing us with that inestimable boon, a full contemporary history of the chief events connected with the controversy up to this time. This treatise, which is addressed to Aurelius, bishop of Carthage, opens with a brief explanation of Augustin's delay heretofore, in discussing Pelagius' defence of himself in Palestine, as due to his not having received the official copy of the Proceedings of the Council at Diospolis (1-2a). Then Augustin proceeds at once to discuss at length the doings of the synod, point by point, following the official record step by step (2b-45). He treats at large here eleven items in the indictment, with Pelagius' answers and the synod's decision, showing that in all of them Pelagius either explained away his heresy, taking advantage of the ignorance of the judges of his books, or else openly repudiated or anathematized it. When the twelfth item of the indictment was reached (41b-43), Augustin shows that the synod was so indignant at its character (it charged Pelagius with teaching that men cannot be sons of God unless they are sinless, and with condoning sins of ignorance, and with asserting that choice is not free if it depends on God's help, and that pardon is given according to merit), that, without waiting for Pelagius' answer, it condemned the statement, and Pelagius at once repudiated and anathematized it (43). How could the synod act in such circumstances, he asks, except by acquitting the man who condemned the heresy? After quoting the final judgment of the synod (44), Augustin briefly characterizes it and its effect (45) as being indeed all that could be asked of the judges, but of no moral weight to those better acquainted than they were with Pelagius' character and writings. In a word, they approved his answers to them, as indeed they ought to have done; but they by no means approved, but both they and he condemned, his heresies as expressed in his writings. To this statement, Augustin appends an account of the origin of Pelagianism, and of his relations to it from the beginning, which has the very highest value as history (46-49); and then speaks of the character and doubtful practices of Pelagius (50-58), returning at the end (59-65) to a thorough canvass of the value of the acquittal which he obtained by such doubtful practices at the synod. He closes with an indignant account of the outrages which the Pelagians had perpetrated on Jerome (66).
This valuable treatise is not, however, the only account of the historical origin of Pelagianism that we have, from Augustin's hands. Soon after the death of Innocent (March 12, 417), he found occasion to write a very long letter  to the venerable Paulinus of Nola, in which he summarized both the history of and the arguments against this "worldly philosophy." He begins by saying that he knows Paulinus has loved Pelagius as a servant of God, but is ignorant in what way he now loves him. For he himself not only has loved him, but loves him still, but in different ways. Once he loved him as apparently a brother in the true faith: now he loves him in the longing that God will by His mercy free him from his noxious opinions against God's grace. He is not merely following report in so speaking of him: no doubt report did for a long time represent this of him, but he gave the less heed to it because report is accustomed to lie. But a book of his  at last came into his hands, which left no room for doubt, since in it he asserted repeatedly that God's grace consisted of the gift to man of the capacity to will and act, and thus reduced it to what is common to pagans and Christians, to the ungodly and godly, to the faithful and infidels. He then gives a brief account of the measures that had been taken against Pelagius, and passes on to a treatment of the main matters involved in the controversy,—all of which gather around the one magic word of "the grace of God." He argues first that we are all lost,—in one mass and concretion of perdition,—and that God's grace alone makes us to differ. It is therefore folly to talk of deserving the beginnings of grace. Nor can a faithful man say that he merits justification by his faith, although it is given to faith; for at once he hears the words, "what hast thou that thou didst not receive?" and learns that even the deserving faith is the gift of God. But if, peering into God's inscrutable judgments, we go farther, and ask why, from the mass of Adam, all of which undoubtedly has fallen from one into condemnation, this vessel is made for honor, that for dishonor,—we can only say that we do not know more than the fact; and God's reasons are hidden, but His acts are just. Certain it is that Paul teaches that all die in Adam; and that God freely chooses, by a sovereign election, some out of that sinful mass, to eternal life; and that He knew from the beginning to whom He would give this grace, and so the number of the saints has always been fixed, to whom he gives in due time the Holy Ghost. Others, no doubt, are called; but no others are elect, or "called according to his purpose." On no other body of doctrines, can it be possibly explained that some infants die unbaptized, and are lost. Is God unjust to punish innocent children with eternal pains? And are they not innocent if they are not partakers of Adam's sin? And can they be saved from that, save by the undeserved, and that is the gratuitous, grace of God? The account of the Proceedings at the Palestinian synod is then taken up, and Pelagius' position in his latest writings is quoted and examined. "But why say more?" he adds...."Ought they not, since they call themselves Christians, to be more careful than the Jews that they do not stumble at the stone of offence, while they subtly defend nature and free will just like philosophers of this world who vehemently strive to be thought, or to think themselves, to attain for themselves a happy life by the force of their own will? Let them take care, then, that they do not make the cross of Christ of none effect by the wisdom of word (1 Corinthians 1:17), and thus stumble at the rock of offence. For human nature, even if it had remained in that integrity in which it was created, could by no means have served its own Creator without His aid. Since then, without God's grace it could not keep the safety it had received, how can it without God's grace repair what it has lost?" With this profound view of the Divine immanence, and of the necessity of His moving grace in all the acts of all his creatures, as over against the heathen-deistic view of Pelagius, Augustin touched in reality the deepest point in the whole controversy, and illustrated the essential harmony of all truth. 
The sharpest period of the whole conflict was now drawing on.  Innocent's death brought Zosimus to the chair of the Roman See, and the efforts which he made to re-instate Pelagius and Coelestius now began (September, 417). How little the Africans were likely to yield to his remarkable demands, may be seen from a sermon  which Augustin preached on the 23d of September, while Zosimus' letter (written on the 21st of September) was on its way to Africa. The preacher took his text from John 6:54-66. "We hear here," he said, "the true Master, the Divine Redeemer, the human Saviour, commending to us our ransom, His blood. He calls His body food, and His blood drink; and, in commending such food and drink, He says, Unless you eat My flesh, and drink My blood, ye shall have no life in you.' What, then, is this eating and drinking, but to live? Eat life, drink life; you shall have life, and life is whole. This will come,—that is, the body and blood of Christ will be life to every one,—if what is taken visibly in the sacrament is in real truth spiritually eaten and spiritually drunk. But that He might teach us that even to believe in Him is of gift, not of merit, He said, No one comes to Me, except the Father who sent Me draw him.' Draw him, not lead him. This violence is done to the heart, not the flesh. Why do you marvel? Believe, and you come; love, and you are drawn. Think not that this is harsh and injurious violence; it is soft, it is sweet; it is sweetness itself that draws you. Is not the sheep drawn when the succulent herbage is shown to him? And I think that there is no compulsion of the body, but an assembling of the desire. So, too, do you come to Christ; wish not to plan a long journey,—when you believe, then you come. For to Him who is everywhere, one comes by loving, not by taking a voyage. No doubt, if you come not, it is your work; but if you come, it is God's work. And even after you have come, and are walking in the right way, become not proud, lest you perish from it: happy are those that confide in Him,' not in themselves, but in Him. We are saved by grace, not of ourselves: it is the gift of God. Why do I continually say this to you? It is because there are men who are ungrateful to grace, and attribute much to unaided and wounded nature. It is true that man received great powers of free will at his creation; but he lost them by sinning. He has fallen into death; he has been made weak; he has been left half dead in the way, by robbers; the good Samaritan has lifted him up upon his ass, and borne him to the inn. Why should we boast? But I am told that it is enough that sins are remitted in baptism. But does the removal of sin take away weakness too? What! will you not see that after pouring the oil and the wine into the wounds of the man left half dead by the robbers, he must still go to the inn where his weakness may be healed? Nay, so long as we are in this life we bear a fragile body; it is only after we are redeemed from corruption that we shall find no sin, and receive the crown of righteousness. Grace, that was hidden in the Old Testament, is now manifest to the whole world. Even though the Jew may be ignorant of it, why should Christians be enemies of grace? why presumptuous of themselves? why ungrateful to grace? For, why did Christ come? Was not nature already here,—that very nature by the praise of which you are beguiled? Was not the law here? But the apostle says, If righteousness is of the law, then is Christ dead in vain.' What the apostle says of the law, that we say to these men about nature: if righteousness is by nature, then Christ is dead in vain. What then was said of the Jews, this we see repeated in these men. They have a zeal for God: I bear them witness that they have a zeal for God, but not according to knowledge. For, being ignorant of God's righteousness, and wishing to establish their own, they are not subject to the righteousness of God. My brethren, share my compassion. Where you find such men, wish no concealment; let there be no perverse pity in you: where you find them, wish no concealment at all. Contradict and refute, resist, or persuade them to us. For already two councils have, in this cause, sent letters to the Apostolic See, whence also rescripts have come back. The cause is ended: would that the error might some day end! Therefore we admonish so that they may take notice, we teach so that they may be instructed, we pray so that their way be changed." Here is certainly tenderness to the persons of the teachers of error; readiness to forgive, and readiness to go all proper lengths in recovering them to the truth. But here is also absolute firmness as to the truth itself, and a manifesto as to policy. Certainly, on the lines of the policy here indicated, the Africans fought out the coming campaign. They met in council at the end of this year, or early in the next (418); and formally replied to Zosimus, that the cause had been tried, and was finished, and that the sentence that had been already pronounced against Pelagius and Coelestius should remain in force until they should unequivocally acknowledge that "we are aided by the grace of God through Christ, not only to know, but to do, what is right, and that in each single act; so that without grace we are unable to have, think, speak, or do anything belonging to piety." As we may see Augustin's hand in this, so, doubtless, we may recognize it in that remarkable piece of engineering which crushed Zosimus' plans within the next few months. There is, indeed, no direct proof that it was due to Augustin, or to the Africans under his leading, or to the Africans at all, that the State interfered in the matter; it is even in doubt whether the action of the Empire was put forth as a rescript, or as a self-moved decree: but surely it is difficult to believe that such a coup de théâtrecould have been prepared for Zosimus by chance; and as it is well known, both that Augustin believed in the righteousness of civil penalty for heresy, and invoked it on other occasions, and defended and used it on this, and that he had influential friends at court with whom he was in correspondence, it seems, on internal grounds, altogether probable that he was the Deus ex machinâ who let loose the thunders of ecclesiastical and civil enactment simultaneously on the poor Pope's devoted head.
The "great African Council" met at Carthage, on the 1st of May, 418; and, after its decrees were issued, Augustin remained at Carthage, and watched the effect of the combination of which he was probably one of the moving causes. He had now an opportunity to betake himself once more to his pen. While still at Carthage, at short notice, and in the midst of much distraction, he wrote a large work, in two books which have come down to us under the separate titles of On the Grace of Christ, and On Original Sin, at the instance of another of those ascetic families which formed so marked a feature in those troubled times. Pinianus and Melania, the daughter of Albina, were husband and wife, who, leaving Rome amid the wars with Alaric, had lived in continence in Africa for some time, but now in Palestine had separated, he to become head of a monastery, and she an inmate of a convent. While in Africa, they had lived at Sagaste under the tutelage of Alypius, and in the enjoyment of the friendship and instruction of Augustin. After retiring to Bethlehem, like the other holy ascetics whom he had known in Africa, they kept up their relations with him. Like the others, also, they became acquainted with Pelagius in Palestine, and were well-nigh deceived by him. They wrote to Augustin that they had begged Pelagius to condemn in writing all that had been alleged against him, and that he had replied in the presence of them all, that "he anathematized the man who either thinks or says that the grace of God whereby Christ Jesus came into the world to save sinners is not necessary, not only for every hour and for every moment, but also for every act of our lives," and asserted that "those who endeavor to disannul it are worthy of everlasting punishment."  Moreover, they wrote that Pelagius had read to them, out of his book that he had sent to Rome,  his assertion "that infants ought to be baptized with the same formula of sacramental words as adults."  They wrote that they were delighted to hear these words from Pelagius, as they seemed exactly what they had been desirous of hearing; and yet they preferred consulting Augustin about them, before they were fully committed regarding them.  It was in answer to this appeal, that the present work was written; the two books of which take up the two points in Pelagius' asseveration,—the theme of the first being "the assistance of the Divine grace towards our justification, by which God co-operates in all things for good to those who love Him, and whom He first loved, giving to them that He may receive from them,"—while the subject of the second is "the sin which by one man has entered the world along with death, and so has passed upon all men." 
The first book, On the Grace of Christ, begins by quoting and examining Pelagius' anathema of all those who deny that grace is necessary for every action (2 sq.). Augustin confesses that this would deceive all who were not fortified by knowledge of Pelagius' writings; but asserts that in the light of them it is clear that he means that grace is always necessary, because we need continually to remember the forgiveness of our sins, the example of Christ, the teaching of the law, and the like. Then he enters (4 sq.) upon an examination of Pelagius' scheme of human faculties, and quotes at length his account of them given in his book, In Defence of Free Will, wherein he distinguishes between the possibilitas (posse), voluntas (velle), and actio (esse), and declares that the first only is from God and receives aid from God, while the others are entirely ours, and in our own power. Augustin opposes to this the passage in Philippians 2:12, 13 (6), and then criticises (7 sq.) Pelagius' ambiguous acknowledgment that God is to be praised for man's good works, "because the capacity for any action on man's part is from God," by which he reduces all grace to the primeval endowment of nature with "capacity" (possibilitas, posse), and the help afforded it by the law and teaching. Augustin points out the difference between law and grace, and the purpose of the former as a pedagogue to the latter (9 sq.), and then refutes Pelagius' further definition of grace as consisting in the promise of future glory and the revelation of wisdom, by an appeal to Paul's thorn in the flesh, and his experience under its discipline (11 sq.). Pelagius' illustrations from our senses, of his theory of natural faculty, are then sharply tested (16); and the criticism on the whole doctrine is then made and pressed (17 sq.), that it makes God equally sharer in our blame for evil acts as in our praise for good ones, since if God does help, and His help is only His gift to us of ability to act in either part, then He has equally helped to the evil deeds as to the good. The assertion that this "capacity of either part" is the fecund root of both good and evil is then criticised (19 sq.), and opposed to Matthew 7:18, with the result of establishing that we must seek two roots in our dispositions for so diverse results,—covetousness for evil, and love for good,—not a single root for both in nature. Man's "capacity," it is argued, is the root of nothing; but it is capable of both good and evil according to the moving cause, which, in the case of evil, is man-originated, while, in the case of good, it is from God (21). Next, Pelagius' assertion that grace is given according to our merits (23 sq.) is taken up and examined. It is shown, that, despite his anathema, Pelagius holds to this doctrine, and in so extreme a form as explicitly to declare that man comes and cleaves to God by his freedom of will alone, and without God's aid. He shows that the Scriptures teach just the opposite (24-26); and then points out how Pelagius has confounded the functions of knowledge and love (27 sq.), and how he forgets that we cannot have merits until we love God, while John certainly asserts that God loved us first (1 John 4:10). The representation that what grace does is to render obedience easier (28-30), and the twin view that prayer is only relatively necessary, are next criticised (32). That Pelagius never acknowledges real grace, is then demonstrated by a detailed examination of all that he had written on the subject (31-45). The book closes (46-80) with a full refutation of Pelagius' appeal to Ambrose, as if he supported him; and exhibition of Ambrose's contrary testimony as to grace and its necessity.
The object of the second book—On Original Sin—is to show, that, in spite of Pelagius' admissions as to the baptism of infants, he yet denies that they inherit original sin and contends that they are born free from corruption. The book opens by pointing out that there is no question as to Coelestius' teaching in this matter (2-8), as he at Carthage refused to condemn those who say that Adam's sin injured no one but himself, and that infants are born in the same state that Adam was in before the fall, and openly asserted at Rome that there is no sin ex traduce. As for Pelagius, he is simply more cautious and mendacious than Coelestius: he deceived the Council at Diospolis, but failed to deceive the Romans (5-13), and, as a matter of fact (14-18), teaches exactly what Coelestius does. In support of this assertion, Pelagius' Defence of Free Will is quoted, wherein he asserts that we are born neither good nor bad, "but with a capacity for either," and "as without virtue, so without vice; and previous to the action of our own proper will, that that alone is in man which God has formed" (14). Augustin also quotes Pelagius' explanation of his anathema against those who say Adam's sin injured only himself, as meaning that he has injured man by setting a bad "example," and his even more sinuous explanation of his anathema against those who assert that infants are born in the same condition that Adam was in before he fell, as meaning that they are infants and he was a man! (16-18). With this introduction to them, Augustin next treats of Pelagius' subterfuges (19-25), and then animadverts on the importance of the issue (26-37), pointing out that Pelagianism is not a mere error, but a deadly heresy, and strikes at the very centre of Christianity. A counter argument of the Pelagians is then answered (38-45), "Does not the doctrine of original sin make marriage an evil thing?" No, says Augustin, marriage is ordained by God, and is good; but it is a diseased good, and hence what is born of it is a good nature made by God, but this good nature in a diseased condition,—the result of the Devil's work. Hence, if it be asked why God's gift produces any thing for the Devil to take possession of, it is to be answered that God gives his gifts liberally (Matthew 5:45), and makes men; but the Devil makes these men sinners (46). Finally, as Ambrose had been appealed to in the former book, so at the end of this it is shown that he openly proclaimed the doctrine of original sin, and here too, before Pelagius, condemned Pelagius (47 sq.).
What Augustin means by writing to Pinianus and his family that he was more oppressed by work at Carthage than anywhere else, may perhaps be illustrated from his diligence in preaching while in that capital. He seems to have been almost constantly in the pulpit, during this period "of the sharpest conflict with them,"  preaching against the Pelagians. There is one series of his sermons, of the exact dates of which we can be pretty sure, which may be adverted to here,—Sermons 151 and 152, preached early in October, 418; Sermon 155 on Oct.14, 156 on Oct.17, and 26 on Oct.18; thus following one another almost with the regularity of the days. The first of these was based on Romans 7:15-25, which he declares to contain dangerous words if not properly understood; for men are prone to sin, and when they hear the apostle so speaking they do evil, and think they are like him. They are meant to teach us, however, that the life of the just in this body is a war, not yet a triumph: the triumph will come only when death is swallowed up in victory. It would, no doubt, be better not to have an enemy than even to conquer. It would be better not to have evil desires: but we have them; therefore, let us not go after them. If they rebel against us, let us rebel against them; if they fight, let us fight; if they besiege, let us besiege: let us look only to this, that they do not conquer. With some evil desires we are born: others we make, by bad habit. It is on account of those with which we are born, that infants are baptized; that they may be freed from the guilt of inheritance, not from any evil of custom, which, of course, they have not. And it is on account of these, too, that our war must be endless: the concupiscence with which we are born cannot be done away as long as we live; it may be diminished, but not done away. Neither can the law free us, for it only reveals the sin to our greater apprehension. Where, then, is hope, save in the superabundance of grace? The next sermon (152) takes up the words in Romans 8:1-4, and points out that the inward aid of the Spirit brings all the help we need. "We, like farmers in the field, work from without: but, if there were no one who worked from within, the seed would not take root in the ground, nor would the sprout arise in the field, nor would the shoot grow strong and become a tree, nor would branches and fruit and leaves be produced. Therefore the apostle distinguishes between the work of the workmen and of the Creator (1 Corinthians 3:6, 7). If God give not the increase, empty is this sound within your ears; but if he gives, it avails somewhat that we plant and water, and our labor is not in vain." He then applies this to the individual, striving against his lusts; warns against Manichean error; and distinguishes between the three laws,—the law of sin, the law of faith, and the law of deeds,—defending the latter, the law of Moses, against the Manicheans; and then he comes to the words of the text, and explains its chief phrases, closing thus: "What other do we read here than that Christ is a sacrifice for sin?...Behold by what sin' he condemned sin: by the sacrifice which he made for sins, he condemned sin. This is the law of the Spirit of life which has freed you from the law of sin and death. For that other law, the law of the letter, the law that commands, is indeed good; the commandment is holy and just and good:' but it was weak by the flesh,' and what it commanded it could not bring about in us. Therefore there is one law, as I began by saying, that reveals sin to you, and another that takes it away: the law of the letter reveals sin, the law of grace takes it away." Sermon 155 covers the same ground, and more, taking the broader text, Romans 8:1-11, and fully developing its teaching, especially as discriminating between the law of sin and the law of Moses and the law of faith; the law of Moses being the holy law of God written with His finger on the tables of stone, while the law of the Spirit of life is nothing other than the same law written in the heart, as the prophet (Jeremiah 30:1, 33) clearly declares. So written, it does not terrify from without, but soothes from within. Great care is also taken, lest by such phrases as, "walk in the Spirit, not in the flesh," "who shall deliver me from the body of this death?" a hatred of the body should be begotten. "Thus you shall be freed from the body of this death, not by having no body, but by having another one and dying no more. If, indeed, he had not added, of this death,' perchance an error might have been suggested to the human mind, and it might have been said, You see that God does not wish us to have a body.' But He says, the body of this death.' Take away death, and the body is good. Let our last enemy, death, be taken away, and my dear flesh will be mine for eternity. For no one can ever hate his own flesh.' Although the spirit lusts against the flesh, and the flesh against the spirit,' although there is now a battle in this house, yet the husband is seeking by his strife not the ruin of, but concord with, his wife. Far be it, far be it, my brethren, that the spirit should hate the flesh in lusting against it! It hates the vices of the flesh; it hates the wisdom of the flesh; it hates the contention of death. This corruption shall put on incorruption,—this mortal shall put on immortality; it is sown a natural body; it shall rise a spiritual body; and you shall see full and perfect concord,—you shall see the creature praise the Creator." One of the special interests of such passages is to show, that, even at this early date, Augustin was careful to guard his hearers from Manichean error while proclaiming original sin. One of the sermons which, probably, was preached about this time (153), is even entitled, "Against the Manicheans openly, but tacitly against the Pelagians," and bears witness to the early development of the method that he was somewhat later to use effectively against Julian's charges of Manicheanism against the catholics.  Three days afterwards, Augustin preached on the next few verses, Romans 8:12-17, but can scarcely be said to have risen to the height of its great argument. The greater part of the sermon is occupied with a discussion of the law, why it was given, how it is legitimately used, and its usefulness as a pedagogue to bring us to Christ; then of the need of a mediator; and then, of what it is to live according to the flesh, which includes living according to merely human nature; and the need of mortifying the flesh in this world. All this, of course, gave full opportunity for opposing the leading Pelagian errors; and the sermon is brought to a close by a direct polemic against their assertion that the function of grace is only to make it more easy to do what is right. "With the sail more easily, with the oar with more difficulty: nevertheless even with the oar we can go. On a beast more easily, on foot with more difficulty: nevertheless progress can be made on foot. It is not true! For the true Master who flatters no one, who deceives no one,—the truthful Teacher and very Saviour to whom the most grievous pedagogue has led us,—when he was speaking about good works, i.e., about the fruits of the twigs and branches, did not say, Without me, indeed, you can do something, but you will do it more easily with me;' He did not say, You can make your fruit without me, but more richly with me.' He did not say this! Read what He said: it is the holy gospel,—bow the proud necks! Augustin does not say this: the Lord says it. What says the Lord? Without me you can do nothing!'" On the very next day, he was again in the pulpit, and taking for his text chiefly the ninety-fourth Psalm.  The preacher began  by quoting the sixth verse, and laying stress on the words "our Maker." No Christian,' he said, doubted that God had made him, and that in such a sense that God created not only the first man, from whom all have descended, but that God to-day creates every man,—as He said to one of His saints, "Before that I formed thee in the womb, I knew thee." At first He created man apart from man; now He creates man from man: nevertheless, whether man apart from man, or man from man, "it is He that made us, and not we ourselves." Nor has He made us and then deserted us; He has not cared to make us, and not cared to keep us. Will He who made us without being asked, desert us when He is besought? But is it not just as foolish to say, as some say or are ready to say, that God made them men, but they make themselves righteous? Why, then, do we pray to God to make us righteous? The first man was created in a nature that was without fault or flaw. He was made righteous: he did not make himself righteous; what he did for himself was to fall and break his righteousness. This God did not do: He permitted it, as if He had said, "Let him desert Me; let him find himself; and let his misery prove that he has no ability without Me." In this way God wished to show man what free will was worth without God. O evil free will without God! Behold, man was made good; and by free will man was made evil! When will the evil man make himself good by free will? When good, he was not able to keep himself good; and now that he is evil, is he to make himself good? Nay, behold, He that made us has also made us "His people" (Psalm 94:7). This is a distinguishing gift. Nature is common to all, but grace is not. It is not to be confounded with nature; but if it were, it would still be gratuitous. For certainly no man, before he existed, deserved to come into existence. And yet God has made him, and that not like the beasts or a stock or a stone, but in His own image. Who has given this benefit? He gave it who was in existence: he received it who was not. And only He could do this, who calls the things that are not as though they were: of whom the apostle says that "He chose us before the foundation of the world." We have been made in this world, and yet the world was not when we were chosen. Ineffable! wonderful! They are chosen who are not: neither does He err in choosing, nor choose in vain. He chooses, and has elect whom He is to create to be chosen: He has them in Himself; not indeed in His nature, but in His prescience. Let us not, then, glory in ourselves, or dispute against grace. If we are men, He made us. If we are believers, He made us this too. He who sent the Lamb to be slain has, out of wolves, made us sheep. This is grace. And it is an even greater grace than that grace of nature by which we were all made men.' "I am continually endeavouring to discuss such things as these," said the preacher, "against a new heresy which is attempting to rise; because I wish you to be fixed in the good, untouched by the evil....For, disputing against grace in favor of free will, they became an offence to pious and catholic ears. They began to create horror; they began to be avoided as a fixed pest; it began to be said of them, that they argued against grace. And they found such a device as this: Because I defend man's free will, and say that free will is sufficient in order that I may be righteous,' says one, I do not say that it is without the grace of God.' The ears of the pious are pricked up, and he who hears this, already begins to rejoice: Thanks be to God! He does not defend free will without the grace of God! There is free will, but it avails nothing without the grace of God.' If, then, they do not defend free will without the grace of God, what evil do they say? Expound to us, O teacher, what grace you mean? When I say,' he says, the free will of man, you observe that I say "of man"?' What then? Who created man?' God. Who gave him free will?' God. If, then, God created man, and God gave man free will, whatever man is able to do by free will, to whose grace does he owe it, except to His who made him with free will?' And this is what they think they say so acutely! You see, nevertheless, my brethren, how they preach that general grace by which we were created and by which we are men; and, of course, we are men in common with the ungodly, and are Christians apart from them. It is this grace by which we are Christians, that we wish them to preach, this that we wish them to acknowledge, this that we wish,—of which the apostle says, I do not make void the grace of God, for if righteousness is by the law, Christ is dead in vain.'" Then the true function of the law is explained, as a revealer of our sinfulness, and a pedagogue to lead us to Christ: the Manichean view of the Old Testament law is attacked, but its insufficiency for salvation is pointed out; and so we are brought back to the necessity of grace, which is illustrated from the story of the raising of the dead child in 2 Kings 4:18-37,—the dead child being Adam; the ineffective staff (by which we ought to walk), the law; but the living prophet, Christ with his grace, which we must preach. "The prophetic staff was not enough for the dead boy: would dead nature itself have been enough? Even this, by which we are made, although we nowhere read of it under this name, we nevertheless, because it is given gratuitously, confess to be grace. But we show to you a greater grace than this, by which we are Christians....This is the grace by Jesus Christ our Lord: it was He that made us,—both before we were at all, it was He that made us, and now, after we are made, it is He that has made us all righteous,—and not we ourselves." There was but one mass of perdition from Adam, to which nothing was due but punishment; and from that mass vessels have been made unto honor. "Rejoice because you have escaped; you have escaped the death that was due,—you have received the life that was not due. But,' you ask, why did He make me unto honor, and another unto dishonor?' Will you who will not hear the apostle saying, O man, who art thou that repliest against God?' hear Augustin?...Do you wish to dispute with me? Nay, wonder with me, and cry out with me, Oh the depth of the riches!' Let us both be afraid,—let us both cry out, Oh the depth of the riches!' Let us both agree in fear, lest we perish in error."
Augustin was not less busy with his pen, during these months, than with his voice. Quite a series of letters belong to the last half of 418, in which he argues to his distant correspondents on the same themes which he was so iterantly trying to make clear to his Carthaginian auditors. One of the most interesting of these was written to a fellow-bishop, Optatus, on the origin of the soul.  Optatus, like Jerome, had expressed himself as favoring the theory of a special creation of each at birth; and Augustin, in this letter as in the paper sent to Jerome, lays great stress on so holding our theories on so obscure a matter as to conform to the indubitable fact of the transmission of sin. This fact, such passages as 1 Corinthians 15:21 sq., Romans 5:12 sq., make certain; and in stating this, Augustin takes the opportunity to outline the chief contents of the catholic faith over against the Pelagian denial of original sin and grace: that all are born under the contagion of death and in the bond of guilt; that there is no deliverance except in the one Mediator, Christ Jesus; that before His coming men received him as promised, now as already come, but with the same faith; that the law was not intended to save, but to shut up under sin and so force us back upon the one Saviour; and that the distribution of grace is sovereign. Augustin pries into God's sovereign counsels somewhat more freely here than is usual with him. "But why those also are created who, the Creator foreknew, would belong to damnation, not to grace, the blessed apostle mentions with as much succinct brevity as great authority. For he says that God, wishing to show His wrath and demonstrate His power,' etc. (Romans 9:22). Justly, however, would he seem unjust in forming vessels of wrath for perdition, if the whole mass from Adam were not condemned. That, therefore, they are made on birth vessels of anger, belongs to the punishment due to them; but that they are made by re-birth vessels of mercy, belongs to the grace that is not due to them. God, therefore, shows his wrath,—not, of course, perturbation of mind, such as is called wrath among men, but a just and fixed vengeance....He shows also his power, by which he makes a good use of evil men, and endows them with many natural and temporal goods, and bends their evil to admonition and instruction of the good by comparison with it, so that these may learn from them to give thanks to God that they have been made to differ from them, not by their own deserts which were of like kind in the same mass, but by His pity....But by creating so many to be born who, He foreknew, would not belong to his grace, so that they are more by an incomparable multitude than those whom he deigned to predestinate as children of the promise into the glory of His Kingdom,—He wished to show by this very multitude of the rejected how entirely of no moment it is to the just God what is the multitude of those most justly condemned. And that hence also those who are redeemed from this condemnation may understand, that what they see rendered to so great a part of the mass was the due of the whole of it,—not only of those who add many others to original sin, by the choice of an evil will, but as well of so many children who are snatched from this life without the grace of the Mediator, bound by no bond except that of original sin alone." With respect to the question more immediately concerning which the letter was written, Augustin explains that he is willing to accept the opinion that souls are created for men as they are born, if only it can be made plain that it is consistent with the original sin that the Scriptures so clearly teach. In the paper sent to Jerome, the difficulties of creationism are sufficiently urged; this letter is interesting on account of its statement of some of the difficulties of traducianism also,—thus evidencing Augustin's clear view of the peculiar complexity of the problem, and justifying his attitude of balance and uncertainty between the two theories. The human understanding,' he says, can scarcely comprehend how a soul arises from a parent's soul in the offspring; or is transmitted to the offspring as a candle is lighted from a candle and thence another fire comes into existence without loss to the former one. Is there an incorporeal seed for the soul, which passes, by some hidden and invisible channel of its own, from the father to the mother, when it is conceived in the woman? Or, even more incredible, does it lie enfolded and hidden within the corporeal seed?' He is lost in wonder over the question whether, when conception does not take place, the immortal seed of an immortal soul perishes; or, does the immortality attach itself to it only when it lives? He even expresses the doubt whether traducianism will explain what it is called in to explain, much better than creationism; in any case, who denies that God is the maker of every soul? Isaiah (lvii.16) says, "I have made every breath;" and the only question that can arise is as to method,—whether He "makes every breath from the one first breath, just as He makes every body of man from the one first body; or whether he makes new bodies indeed, from the one body, but new souls out of nothing." Certainly nothing but Scripture can determine such a question; but where do the Scriptures speak unambiguously upon it? The passages to which the creationists point only affirm the admitted fact that God makes the soul; and the traducianists forget that the word "soul" in the Scriptures is ambiguous, and can mean "man," and even a "dead man." What more can be done, then, than to assert what is certain, viz., that sin is propagated, and leave what is uncertain in the doubt in which God has chosen to place it?
This letter was written not long after the issue of Zosimus' Tractoria, demanding the signature of all to African orthodoxy; and Augustin sends Optatus "copies of the recent letters which have been sent forth from the Roman see, whether specially to the African bishops or generally to all bishops," on the Pelagian controversy, "lest perchance they had not yet reached" his correspondent, who, it is very evident, he was anxious should thoroughly realize "that the authors, or certainly the most energetic and noted teachers," of these new heresies, "had been condemned in the whole Christian world by the vigilance of episcopal councils aided by the Saviour who keeps His Church, as well as by two venerable overseers of the Apostolical see, Pope Innocent and Pope Zosimus, unless they should show repentance by being convinced and reformed." To this zeal we owe it that the letter contains an extract from Zosimus' Tractoria, one of the two brief fragments of that document that have reached our day.
There was another ecclesiastic in Rome, besides Zosimus, who was strongly suspected of favoring the Pelagians,—the presbyter Sixtus, who afterwards became Pope Sixtus III. But when Zosimus sent forth his condemnation of Pelagianism, Sixtus sent also a short letter to Africa addressed to Aurelius of Carthage, which, though brief, indicated a considerable vigor against the heresy which he was commonly believed to have before defended,  and which claimed him as its own.  Some months afterwards, he sent another similar, but longer, letter to Augustin and Alypius, more fully expounding his rejection of "the fatal dogma" of Pelagius, and his acceptance of "that grace of God freely given by Him to small and great, to which Pelagius' dogma was diametrically opposed." Augustin was overjoyed with these developments. He quickly replied in a short letter  in which he expresses the delight he has in learning from Sixtus' own hand that he is not a defender of Pelagius, but a preacher of grace. And close upon the heels of this he sent another much longer letter,  in which he discusses the subtler arguments of the Pelagians with an anxious care that seems to bear witness to his desire to confirm and support his correspondent in his new opinions. Both letters testify to Augustin's approval of the persecuting measures which had been instituted by the Roman see in obedience to the emperor; and urge on Sixtus his duty not only to bring the open heretics to deserved punishment, but to track out those who spread their poison secretly, and even to remember those whom he had formerly heard announcing the error before it had been condemned, and who were now silent through fear, and to bring them either to open recantation of their former beliefs, or to punishment. It is pleasanter to recall our thoughts to the dialectic of these letters. The greater part of the second is given to a discussion of the gratuitousness of grace, which, just because grace, is given to no preceding merits. Many subtle objections to this doctrine were brought forward by the Pelagians. They said that "free will was taken away if we asserted that man did not have even a good will without the aid of God;" that we made "God an accepter of persons, if we believed that without any preceding merits He had mercy on whom He would, and whom He would He called, and whom He would He made religious;" that "it was unjust, in one and the same case, to deliver one and punish another;" that, if such a doctrine is preached, "men who do not wish to live rightly and faithfully, will excuse themselves by saying that they have done nothing evil by living ill, since they have not received the grace by which they might live well;" that it is a puzzle "how sin can pass over to the children of the faithful, when it has been remitted to the parents in baptism;" that "children respond truly by the mouth of their sponsors that they believe in remission of sins, but not because sins are remitted to them, but because they believe that sins are remitted in the church or in baptism to those in whom they are found, not to those in whom they do not exist," and consequently they said that "they were unwilling that infants should be so baptized unto remission of sins as if this remission took place in them," for (they contend) "they have no sin; but they are to be baptized, although without sin, with the same rite of baptism through which remission of sins takes place in any that are sinners." This last objection is especially interesting  because it furnishes us with the reply which the Pelagians made to the argument that Augustin so strongly pressed against them from the very act and ritual of baptism, as implying remission of sins.  His rejoinder to it here is to point to the other parts of the same ritual, and to ask why, then, infants are exorcised and exsufflated in baptism. "For, it cannot be doubted that this is done fictitiously, if the Devil does not rule over them; but if he rules over them, and they are therefore not falsely exorcised and exsufflated, why does that prince of sinners rule over them except because of sin?" On the fundamental matter of the gratuitousness of grace, this letter is very explicit. "If we seek for the deserving of hardening, we shall find it....But if we seek for the deserving of pity, we shall not find it; for there is none, lest grace be made a vanity if it is not given gratis, but rendered to merits. But, should we say that faith preceded and in it there is desert of grace, what desert did man have before faith that he should receive faith? For, what did he have that he did not receive? and if he received it, why does he glory as if he received it not? For as man would not have wisdom, understanding, prudence, fortitude, knowledge, piety, fear of God, unless he had received (according to the prophet) the spirit of wisdom and understanding, of prudence and fortitude, of knowledge and piety and the fear of God; as he would not have justice, love, continence, except the spirit was received of whom the apostle says, For you did not receive the spirit of fear, but of virtue, and love, and continence:' so he would not have faith unless he received the spirit of faith of whom the same apostle says, Having then the same spirit of faith, according to what is written, "I believed and therefore spoke," we too believe and therefore speak.' But that He is not received by desert, but by His mercy who has mercy on whom He will, is manifestly shown where he says of himself, I have obtained mercy to be faithful.'" "If we should say that the merit of prayer precedes, that the gift of grace may follow,...even prayer itself is found among the gifts of grace" (Romans 8:26). "It remains, then, that faith itself, whence all righteousness takes beginning;...it remains, I say, that even faith itself is not to be attributed to the human will which they extol, nor to any preceding merits, since from it begin whatever good things are merits: but it is to be confessed to be the gratuitous gift of God, since we consider it true grace, that is, without merits, inasmuch as we read in the same epistle, God divides out the measure of faith to each' (Romans 12:3). Now, good works are done by man, but faith is wrought in man, and without it these are not done by any man. For all that is not of faith is sin" (Romans 14:23).
By the same messenger who carried this important letter to Sixtus, Augustin sent also a letter to Mercator,  an African layman who was then apparently at Rome, but who was afterwards (in 429) to render service by instructing the Emperor Theodosius as to the nature and history of Pelagianism, and so preventing the appeal of the Pelagians to him from being granted. Now he appears as an inquirer: Augustin, while at Carthage, had received a letter from him in which he had consulted him on certain questions that the Pelagians had raised, but in such a manner as to indicate his opposition to them. Press of business had compelled the postponement of the reply until this later date. One of the questions that Mercator had put concerned the Pelagian account of infants sharing in the one baptism unto remission of sins, which we have seen Augustin answering when writing to Sixtus. In this letter he replies: "Let them, then, hear the Lord (John 3:36). Infants, therefore, who made believers by others, by whom they are brought to baptism, are, of course, unbelievers by others, if they are in the hands of such as do not believe that they should be brought, inasmuch as they believe they are nothing profited; and accordingly, if they believe by believers, and have eternal life, they are unbelievers by unbelievers, and shall not see life, but the wrath of God abideth on them. For it is not said, it comes on them,' but it abideth on them,' because it was on them from the beginning, and will not be taken from them except by the grace of God through Jesus Christ, our Lord....Therefore, when children are baptized, the confession is made that they are believers, and it is not to be doubted that those who are not believers are condemned: let them, then, dare to say now, if they can, that they contract no evil from their origin to be condemned by the just God, and have no contagion of sin." The other matter on which Mercator sought light concerned the statement that universal death proved universal sin:  he reported that the Pelagians replied that not even death was universal,—that Enoch, for instance, and Elijah, had not died. Augustin adds those who are to be found living at the second advent, who are not to die, but be "changed;" and replies that Romans 5:12 is perfectly explicit that there is no death in the world except that which comes from sin, and that God a Saviour, and we cannot at all "deny that He is able to do that, now, in any that he wishes, without death, which we undoubtingly believe is to be done in so many after death." He adds that the difficult question is not why Enoch and Elijah did not die, if death is the punishment of sin; but why, such being the case, the justified ever die; and he refers his correspondent to his book On the Baptism of Infants  for a resolution of this greater difficulty.
It was probably at the very end of 418 that Augustin wrote a letter of some length  to Asellicus, in reply to one which he had written on "avoiding the deception of Judaism," to the primate of the Bizacene province, and which that ecclesiastic had sent to Augustin for answering. He discusses in this the law of the Old Testament. He opens by pointing out that the apostle forbids Christians to Judaize (Galatians 2:14-16), and explains that it is not merely the ceremonial law that we may not depend upon, "but also what is said in the law, Thou shalt not covet' (which no one, of course, doubts is to be said to Christians too), does not justify man, except by faith in Jesus Christ and the grace of God through Jesus Christ our Lord." He then expounds the use of the law: "This, then, is the usefulness of the law: that it shows man to himself, so that he may know his weakness, and see how, by the prohibition, carnal concupiscence is rather increased than healed....The use of the law is, thus, to convince man of his weakness, and force him to implore the medicine of grace that is in Christ." "Since these things are so," he adds, "those who rejoice that they are Israelites after the flesh, and glory in the law apart from the grace of Christ, these are those concerning whom the apostle said that being ignorant of God's righteousness, and wishing to establish their own, they are not subject to God's righteousness;' since he calls God's righteousness' that which is from God to man; and their own,' what they think that the commandments suffice for them to do without the help and gift of Him who gave the law. But they are like those who, while they profess to be Christians, so oppose the grace of Christ, that they suppose that they fulfil the divine commands by human powers, and, wishing to establish their own,' are not subject to the righteousness of God,' and so, not indeed in name, but yet in error, Judaize. This sort of men found heads for themselves in Pelagius and Coelestius, the most acute asserters of this impiety, who by God's recent judgment, through his diligent and faithful servants, have been deprived even of catholic communion, and, on account of an impenitent heart, persist still in their condemnation."
At the beginning of 419, a considerable work was published by Augustin on one of the more remote corollaries which the Pelagians drew from his teachings. It had come to his ears, that they asserted that his doctrine condemned marriage: "if only sinful offspring come from marriage," they asked, "is not marriage itself made a sinful thing?" The book which Augustin composed in answer to this query, he dedicated to, and sent along with an explanatory letter to, the Comes Valerius, a trusted servant of the Emperor Honorius, and one of the most steady opponents at court of the Pelagian heresy. Augustin explains  why he has desired to address the book to him: first, because Valerius was a striking example of those continent husbands of which that age furnishes us with many instances, and, therefore, the discussion would have especial interest for him; secondly, because of his eminence as an opponent of Pelagianism; and, thirdly, because Augustin had learned that he had read a Pelagian document in which Augustin was charged with condemning marriage by defending original sin.  The book in question is the first book of the treatise On Marriage and Concupiscence. It is, naturally, tinged, or rather stained, with the prevalent ascetic notions of the day. Its doctrine is that marriage is good, and God is the maker of the offspring that comes from it, although now there can be no begetting and hence no birth without sin. Sin made concupiscence, and now concupiscence perpetuates sinners. The specific object of the work, as it states it itself, is "to distinguish between the evil of carnal concupiscence, from which man, who is born therefrom, contracts original sin, and the good of marriage" (I.1). After a brief introduction, in which he explains why he writes, and why he addresses his book to Valerius (1-2), Augustin points out that conjugal chastity, like its higher sister-grace of continence, is God's gift. Thus copulation, but only for the propagation of children, has divine allowance (3-5). Lust, or "shameful concupiscence," however, he teaches, is not of the essence, but only an accident, of marriage. It did not exist in Eden, although true marriage existed there; but arose from, and therefore only after, sin (6-7). Its addition to marriage does not destroy the good of marriage: it only conditions the character of the offspring (8). Hence it is that the apostle allows marriage, but forbids the "disease of desire" (1 Thess. iv.3-5); and hence the Old-Testament saints were even permitted more than one wife, because, by multiplying wives, it was not lust, but offspring, that was increased (9-10). Nevertheless, fecundity is not to be thought the only good of marriage: true marriage can exist without offspring, and even without cohabitation (11-13), and cohabitation is now, under the New Testament, no longer a duty as it was under the Old Testament (14-15), but the apostle praises continence above it. We must, then, distinguish between the goods of marriage, and seek the best (16-19). But thus it follows that it is not due to any inherent and necessary evil in marriage, but only to the presence, now, of concupiscence in all cohabitation, that children are born under sin, even the children of the regenerate, just as from the seed of olives only oleasters grow (20-24). And yet again, concupiscence is not itself sin in the regenerate; it is remitted as guilt in baptism: but it is the daughter of sin, and it is the mother of sin, and in the unregenerate it is itself sin, as to yield to it is even to the regenerate (25-39). Finally, as so often, the testimony of Ambrose is appealed to, and it is shown that he too teaches that all born from cohabitation are born guilty (40). In this book, Augustin certainly seems to teach that the bond of connection by which Adam's sin is conveyed to his offspring is not mere descent, or heredity, or mere inclusion in him, in a realistic sense, as partakers of the same numerical nature, but concupiscence. Without concupiscence in the act of generation, the offspring would not be a partaker of Adam's sin. This he had taught also previously, as, e.g., in the treatise On Original Sin, from which a few words may be profitably quoted as succinctly summing up the teaching of this book on the subject: "It is, then, manifest, that that must not be laid to the account of marriage, in the absence of which even marriage would still have existed....Such, however, is the present condition of mortal men, that the connubial intercourse and lust are at the same time in action....Hence it follows that infants, although incapable of sinning, are yet not born without the contagion of sin,...not, indeed, because of what is lawful, but on account of that which is unseemly: for, from what is lawful, nature is born; from what is unseemly, sin" (42).
Towards the end of the same year (419), Augustin was led to take up again the vexed question of the origin of the soul,—both in a new letter to Optatus,  by the zeal of the same monk, Renatus, who had formerly brought Optatus' inquiries to his notice,—in an elaborate treatise entitled On the Soul and its Origin, by way of reply to a rash adventure of a young man named Vincentius Victor, who blamed him for his uncertainty on such a subject, and attempted to determine all the puzzles of the question, though, as Augustin insists, on assumptions that were partly Pelagian and partly worse. Optatus had written in the hope that Augustin had heard by this time from Jerome, in reply to the treatise he had sent him on this subject. Augustin, in answering his letter, expresses his sorrow that he has not yet been worthy of an answer from Jerome, although five years had passed away since he wrote, but his continued hope that such an answer will in due time come. For himself, he confesses that he has not yet been able to see how the soul can contract sin from Adam and yet not itself be contracted from Adam; and he regrets that Optatus, although holding that God creates each soul for its birth, has not sent him the proofs on which he depends for that opinion, nor met its obvious difficulties. He rebukes Optatus for confounding the question of whether God makes the soul, with the entirely different one of how he makes it, whether ex propagine or sive propagine. No one doubts that God makes the soul, as no one doubts that He makes the body. But when we consider how he makes it, sobriety and vigilance become necessary lest we should unguardedly fall into the Pelagian heresy. Augustin defends his attitude of uncertainty, and enumerates the points as to which he has no doubt: viz., that the soul is spirit, not body; that it is rational or intellectual; that it is not of the nature of God, but is so far a mortal creature that it is capable of deterioration and of alienation from the life of God, and so far immortal that after this life it lives on in bliss or punishment forever; that it was not incarnated because of, or according to, preceding deserts acquired in a previous existence, yet that it is under the curse of sin which it derives from Adam, and therefore in all cases alike needs redemption in Christ.
The whole subject of the nature and origin of the soul, however, is most fully discussed in the four books which are gathered together under the common title of On the Soul and its Origin. Vincentius Victor was a young layman who had recently been converted from the Rogatian heresy; on being shown by his friend Peter, a presbyter, a small work of Augustin's on the origin of the soul, he expressed surprise that so great a man could profess ignorance on a matter so intimate to his very being, and, receiving encouragement, wrote a book for Peter in which he attacked and tried to solve all the difficulties of the subject. Peter received the work with transports of delighted admiration; but Renatus, happening that way, looked upon it with distrust, and, finding that Augustin was spoken of in it with scant courtesy, felt it his duty to send him a copy of it, which he did in the summer of 419. It was probably not until late in the following autumn that Augustin found time to take up the matter; but then he wrote to Renatus, to Peter, and two books to Victor himself, and it is these four books together which constitute the treatise that has come down to us. The first book is a letter to Renatus, and is introduced by an expression of thanks to him for sending Victor's book, and of kindly feeling towards and appreciation for the high qualities of Victor himself (1-3). Then Victor's errors are pointed out,—as to the nature of the soul (4-9), including certain far-reaching corollaries that flow from these (10-15), as well as, as to the origin of the soul (16-30); and the letter closes with some remarks on the danger of arguing from the silence of Scripture (31), on the self-contradictions of Victor (34), and on the errors that must be avoided in any theory of the origin of the soul that hopes to be acceptable,—to wit, that souls become sinful by an alien original sin, that unbaptized infants need no salvation, that souls sinned in a previous state, and that they are condemned for sins which they have not committed but would have committed had they lived longer. The second book is a letter to Peter, warning him of the responsibility that rests on him as Victor's trusted friend and a clergyman, to correct Victor's errors, and reproving him for the uninstructed delight he had taken in Victor's crudities. It opens by asking Peter what was the occasion of the great joy which Victor's book brought him? could it be that he learned from it, for the first time, the old and primary truths it contained? (2-3); or was it due to the new errors that it proclaimed,—seven of which he enumerates? (4-16). Then, after animadverting on the dilemma in which Victor stood, of either being forced to withdraw his violent assertion of creationism, or else of making God unjust in His dealings with new souls (17), he speaks of Victor's unjustifiable dogmatism in the matter (18-21), and closes with severely solemn words to Peter on his responsibility in the premises (22-23). In the third and fourth books, which are addressed to Victor, the polemic, of course, reaches its height. The third book is entirely taken up with pointing out to Victor, as a father to a son, the errors into which he has fallen, and which, in accordance with his professions of readiness for amendment, he ought to correct. Eleven are enumerated: 1. That the soul was made by God out of Himself (3-7); 2. That God will continuously create souls forever (8); 3. That the soul has desert of good before birth (9); 4. (contradictingly), That the soul has desert of evil before birth (10); 5. That the soul deserved to be sinful before any sin (11); 6. That unbaptized infants are saved (12); 7. That what God predestinates may not occur (13); 8. That Wisd. iv.1 is spoken of infants (14); 9. That some of the mansions with the Father are outside of God's kingdom (15-17); 10. That the sacrifice of Christ's blood may be offered for the unbaptized (18); 11. That the unbaptized may attain at the resurrection even to the kingdom of heaven (19). The book closes by reminding Victor of his professions of readiness to correct his errors, and warning him against the obstinacy that makes the heretic (20-23). The fourth book deals with the more personal elements of the controversy, and discusses the points in which Victor had expressed dissent from Augustin. It opens with a statement of the two grounds of complaint that Victor had urged against Augustin; viz., that he refused to express a confident opinion as to the origin of the soul, and that he affirmed that the soul was not corporeal, but spirit (1-2). These two complaints are then taken up at length (2-16 and 17-37). To the first, Augustin replies that man's knowledge is at best limited, and often most limited about the things nearest to him; we do not know the constitution of our bodies; and, above most others, this subject of the origin of the soul is one on which no one but God is a competent witness. Who remembers his birth? Who remembers what was before birth? But this is just one of the subjects on which God has not spoken unambiguously in the Scriptures. Would it not be better, then, for Victor to imitate Augustin's cautious ignorance, than that Augustin should imitate Victor's rash assertion of errors? That the soul is not corporeal, Augustin argues (18-35) from the Scriptures and from the phenomena of dreams; and then shows, in opposition to Victor's trichotomy, that the Scriptures teach the identity of "soul" and "spirit" (36-37). The book closes with a renewed enumeration of Victor's eleven errors (38), and a final admonition to his rashness (39). It is pleasant to know that Augustin found in this case, also, that righteousness is the fruit of the faithful wounds of a friend. Victor accepted the rebuke, and professed his better instruction at the hands of his modest but resistless antagonist.
The controversy now entered upon a new stage. Among the evicted bishops of Italy who refused to sign Zosimus' Epistola Tractoria, Julian of Eclanum was easily the first, and at this point he appears as the champion of Pelagianism. It was a sad fate that arrayed this beloved son of his old friend against Augustin, just when there seemed to be reason to hope that the controversy was at an end, and the victory won, and the plaudits of the world were greeting him as the saviour of the Church.  But the now fast-aging bishop was to find, that, in this "very confident young man," he had yet to meet the most persistent and most dangerous advocate of the new doctrines that had arisen. Julian had sent, at an earlier period, two letters to Zosimus, one of which has come down to us as a "Confession of Faith," and the other of which attempted to approach Augustinian forms of speech as much as possible; the object of both being to gain standing ground in the Church for the Italian Pelagians. Now he appears as a Pelagian controversialist; and in opposition to the book On Marriage and Concupiscence, which Augustin had sent Valerius, he published an extended work in four thick books addressed to Turbantius. Extracts from the first of these books were sent by some one to Valerius, and were placed by him in the hands of Alypius, who was then in Italy, for transmission to Augustin. Meanwhile, a letter had been sent to Rome by Julian,  designed to strengthen the cause of Pelagianism there; and a similar one, in the names of the eighteen Pelagianizing Italian bishops, was addressed to Rufus, bishop of Thessalonica, and representative of the Roman see in that portion of the Eastern Empire which was regarded as ecclesiastically a part of the West, the design of which was to obtain the powerful support of this important magnate, perhaps, also, a refuge from persecution within his jurisdiction. These two letters came into the hands of the new Pope, Boniface, who gave them also to Alypius for transmission to Augustin. Thus provided, Alypius returned to Africa. The tactics of all these writings of Julian were essentially the same; he attempted not so much to defend Pelagianism, as to attack Augustinianism, and thus literally to carry the war into Africa. He insisted that the corruption of nature which Augustin taught was nothing else than Manicheism; that the sovereignty of grace, as taught by him, was only the attribution of "acceptance of persons," and partiality, to God; and that his doctrine of predestination was mere fatalism. He accused the anti-Pelagians of denying the goodness of the nature that God had created, of the marriage that He had ordained, of the law that He had given, of the free will that He had implanted in man, as well as the perfection of His saints.  He insisted that this teaching also did dishonour to baptism itself which it professed so to honour, inasmuch as it asserted the continuance of concupiscence after baptism,—and thus taught that baptism does not take away sins, but only shaves them off as one shaves his beard, and leaves the roots whence the sins may grow anew, and need cutting down again. He complained bitterly of the way in which Pelagianism had been condemned,—that bishops had been compelled to sign a definition of dogma, not in council assembled, but sitting at home; and he demanded a rehearing of the whole case before a lawful council, lest the doctrine of the Manichees should be forced upon the acceptance of the world.
Augustin felt a strong desire to see the whole work of Julian against his book On Marriage and Concupiscence before he undertook a reply to the excerpts sent him by Valerius; but he did not feel justified in delaying obedience to that officer's request, and so wrote at once two treatises, one an answer to these excerpts, for the benefit of Valerius, constituting the second book of his On Marriage and Concupiscence; and the other, a far more elaborate examination of the letters sent by Boniface, which bears the title, Against Two Letters of the Pelagians. The purpose of the second book of On Marriage and Concupiscence, Augustin himself states, in its introductory sentences, to be "to reply to the taunts of his adversaries with all the truthfulness and scriptural authority he could command." He begins (2) by identifying the source of the extracts forwarded to him by Valerius, with Julian's work against his first book, and then remarks upon the garbled form in which he is quoted in them (3-6), and passes on to state and refute Julian's charge that the catholics had turned Manicheans (7-9). At this point, the refutation of Julian begins in good earnest, and the method that he proposes to use is stated; viz., to adduce the adverse statements, and refute them one by one (10). Beginning at the beginning, he quotes first the title of the paper sent him, which declares that it is directed against "those who condemn matrimony, and ascribe its fruit to the Devil" (11), which certainly, says Augustin, does not describe him or the catholics. The next twenty chapters (10-30), accordingly, following Julian's order, labour to prove that marriage is good, and ordained by God, but that its good includes fecundity indeed, but not concupiscence, which arose from sin, and contracts sin. It is next argued, that the doctrine of original sin does not imply an evil origin for man (31-51); and in the course of this argument, the following propositions are especially defended: that God makes offspring for good and bad alike, just as He sends the rain and sunshine on just and unjust (31-34); that God makes everything to be found in marriage except its flaw, concupiscence (35-40); that marriage is not the cause of original sin, but only the channel through which it is transmitted (41-47); and that to assert that evil cannot arise from what is good leaves us in the clutches of that very Manicheism which is so unjustly charged against the catholics—for, if evil be not eternal, what else was there from which it could arise but something good? (48-51). In concluding, Augustin recapitulates, and argues especially, that shameful concupiscence is of sin, and the author of sin, and was not in paradise (52-54); that children are made by God, and only marred by the Devil (55); that Julian, in admitting that Christ died for infants, admits that they need salvation (56); that what the Devil makes in children is not a substance, but an injury to a substance (57-58); and that to suppose that concupiscence existed in any form in paradise introduces incongruities in our conception of life in that abode of primeval bliss (59-60).
The long and important treatise, Against Two Letters of the Pelagians, consists of four books, the first of which replies to the letter sent to Rome, and the other three to that sent to Thessalonica. After a short introduction, in which he thanks Boniface for his kindness, and gives reasons why heretical writings should be answered (1-3), Augustin begins at once to rebut the calumnies which the letter before him brings against the catholics (4-28). These are seven in number: 1. That the catholics destroy free will; to which Augustin replies that none are "forced into sin by the necessity of their flesh," but all sin by free will, though no man can have a righteous will save by God's grace, and that it is really the Pelagians that destroy free will by exaggerating it (4-8); 2. That Augustin declares that such marriage as now exists is not of God (9); 3. That sexual desire and intercourse are made a device of the Devil, which is sheer Manicheism (10-11); 4. That the Old-Testament saints are said to have died in sin (12); 5. That Paul and the other apostles are asserted to have been polluted by lust all their days; Augustin's answer to which includes a running commentary on Romans 7:7 sq., in which (correcting his older exegesis) he shows that Paul is giving here a transcript of his own experience as a typical Christian (13-24); 6. That Christ is said not to have been free from sin (25); 7. That baptism does not give complete remission of sins, but leaves roots from which they may again grow; to which Augustin replies that baptism does remit all sins, but leaves concupiscence, which, although not sin, is the source of sin (26-28). Next, the positive part of Julian's letter is taken up, and his profession of faith against the catholics examined (29-41). The seven affirmations that Julian makes here are designed as the obverse of the seven charges against the catholics. He believed: 1. That free will is in all by nature, and could not perish by Adam's sin (29); 2. That marriage, as now existent, was ordained by God (30); 3. That sexual impulse and virility are from God (31-35); 4. That men are God's work, and no one is forced to do good or evil unwillingly, but are assisted by grace to good, and incited by the Devil to evil (36-38); 5. That the saints of the Old Testament were perfected in righteousness here, and so passed into eternal life (39); 6. That the grace of Christ (ambiguously meant) is necessary for all, and all children—even those of baptized parents—are to be baptized (40); 7. And that baptism gives full cleansing from all sins; to which Augustin pointedly asks, "What does it do for infants, then?" (41). The book concludes with an answer to Julian's conclusion, in which he demands a general council, and charges the catholics with Manicheism.
The second, third, and fourth books deal with the letter to Rufus in a somewhat similar way, the second and third books being occupied with the calumnies brought against the catholics, and the fourth with the claims made by the Pelagians. The second begins by repelling the charge of Manicheism brought against the catholics (1-4), to which the pointed remark is added, that the Pelagians cannot hope to escape condemnation because they are willing to condemn another heresy; and then defends (with less success) the Roman clergy against the charge of prevarication in their dealing with the Pelagians (5-8), in the course of which all that can be said in defence of Zosimus' wavering policy is said well and strongly. Next the charges against catholic teaching are taken up and answered (9-16), especially the two important accusations that they maintain fate under the name of grace (9-12), and that they make God an "accepter of persons" (13-16). Augustin's replies to these charges are in every way admirable. The charge of "fate" rests solely on the catholic denial that grace is given according to preceding merits; but the Pelagians do not escape the same charge when they acknowledge that the "fates" of baptized and unbaptized infants do differ. It is, in truth, not a question of "fate," but of gratuitous bounty; and "it is not the catholics that assert fate under the name of grace, but the Pelagians that choose to call divine grace by the name of fate'" (12). As to "acceptance of persons," we must define what we mean by that. God certainly does not accept one's "person" above another's; He does not give to one rather than to another because He sees something to please Him in one rather than another: quite the opposite. He gives of His bounty to one while giving all their due to all, as in the parable (Matthew 20:9 sq.). To ask why He does this, is to ask in vain: the apostle answers by not answering (Romans 9.; and before the dumb infants, who are yet made to differ, all objection to God is dumb. From this point, the book becomes an examination of the Pelagian doctrine of prevenient merit (17-23), concluding that God gives all by grace from the beginning to the end of every process of doing good.1. He commands the good; 2. He gives the desire to do it; and, 3. He gives the power to do it: and all, of His gratuitous mercy. The third book continues the discussion of the calumnies of the Pelagians against the catholics, and enumerates and answers six of them: viz., that the catholics teach, 1. That the Old-Testament law was given, not to justify the obedient, but to serve as cause of greater sin (2-3); 2. That baptism does not give entire remission of sins, but the baptized are partly God's and partly the Devil's (4-5); 3. That the Holy Ghost did not assist virtue in the Old Testament (6-13); 4. That the Bible saints were not holy, but only less wicked than others (14-15); 5. That Christ was a sinner by necessity of His flesh (doubtless, Julian's inference from the doctrine of race-sin) (16); 6. That men will begin to fulfil God's commandments only after the resurrection (17-23). Augustin shows that at the basis of all these calumnies lies either misapprehension or misrepresentation; and, in concluding the book, enumerates the three chief points in the Pelagian heresy, with the five claims growing out of them, of which they most boasted, and then elucidates the mutual relations of the three parties, catholics, Pelagians, and Manicheans, with reference to these points, showing that the catholics stand asunder from both the others, and condemn both (24-27). This conclusion is really a preparation for the fourth book, which takes up these five Pelagian claims, and, after showing the catholic position on them all in brief (1-3), discusses them in turn (4-19): viz., the praise of the creature (4-8), the praise of marriage (9), the praise of the law (10-11), the praise of free will (12-16), and the praise of the saints (17-18). At the end, Augustin calls on the Pelagians to cease to oppose the Manicheans, only to fall into as bad heresy as theirs (19); and then, in reply to their accusation that the catholics were proclaiming novel doctrine, he adduces the testimony of Cyprian and Ambrose, both of whom had received Pelagius' praise, on each of the three main points of Pelagianism (20-32),  and then closes with the declaration that the "impious and foolish doctrine," as they called it, of the catholics, is immemorial truth (33), and with a denial of the right of the Pelagians to ask for a general council to condemn them (34). All heresies do not need an ecumenical synod for their condemnation; usually it is best to stamp them out locally, and not allow what may be confined to a corner to disturb the whole world.
These books were written late in 420, or early in 421, and Alypius appears to have conveyed them to Italy during the latter year. Before its close, Augustin, having obtained and read the whole of Julian's attack on the first book of his work On Marriage and Concupiscence, wrote out a complete answer to it,  —a task that he was all the more anxious to complete, on perceiving that the extracts sent by Valerius were not only all from the first book of Julian's treatise, but were somewhat altered in the extracting. The resulting work, Against Julian, one of the longest that he wrote in the whole course of the Pelagian controversy, shows its author at his best: according to Cardinal Noris's judgment, he appears in it "almost divine," and Augustin himself clearly set great store by it. In the first book of this noble treatise, after professing his continued love for Julian, "whom he was unable not to love, whatever he [Julian] should say against him" (35), he undertakes to show that in affixing the opprobrious name of Manicheans on those who assert original sin, Julian is incriminating many of the most famous fathers, both of the Latin and Greek Churches. In proof of this, he makes appropriate quotations from Irenæus, Cyprian, Reticius, Olympius, Hilary, Ambrose, Gregory Nazianzenus, Basil, John of Constantinople.  Then he argues, that, so far from the catholics falling into Manichean heresy, Julian plays, himself, into the hands of the Manicheans in their strife against the catholics, by many unguarded statements, such as, e.g., when he says that an evil thing cannot arise from what is good, that the work of the Devil cannot be suffered to be diffused by means of a work of God, that a root of evil cannot be placed within a gift of God, and the like. The second book advances to greater detail, and adduces the five great arguments which the Pelagians urged against the catholics, in order to test them by the voice of antiquity. These arguments are stated as follows (2): "For you say, That we, by asserting original sin, affirm that the Devil is the maker of infants, condemn marriage, deny that all sins are remitted in baptism, accuse God of the guilt of sin, and produce despair of perfection.' You contend that all these are consequences, if we believe that infants are born bound by the sin of the first man, and are therefore under the Devil unless they are born again in Christ. For, It is the Devil that creates,' you say, if they are created from that wound which the Devil inflicted on the human nature that was made at first.' And marriage is condemned,' you say, if it is to be believed to have something about it whence it produces those worthy of condemnation.' And all sins are not remitted in baptism,' you say, if there remains any evil in baptized couples whence evil offspring are produced.' And how is God,' you ask, not unjust, if He, while remitting their own sins to baptized persons, yet condemns their offspring, inasmuch as, although it is created by Him, it yet ignorantly and involuntarily contracts the sins of others from those very parents to whom they are remitted?' Nor can men believe,' you add, that virtue—to which corruption is to be understood to be contrary—can be perfected, if they cannot believe that it can destroy the inbred vices, although, no doubt, these can scarcely be considered vices, since he does not sin, who is unable to be other than he was created.'" These arguments are then tested, one by one, by the authority of the earlier teachers who were appealed to in the first book, and shown to be condemned by them. The remaining four books follow Julian's four books, argument by argument, refuting him in detail. In the third book it is urged that although God is good, and made man good, and instituted marriage which is, therefore, good, nevertheless concupiscence is evil, and in it the flesh lusts against the spirit. Although chaste spouses use this evil well, continent believers do better in not using it at all. It is pointed out, how far all this is from the madness of the Manicheans, who dream of matter as essentially evil and co-eternal with God; and shown that evil concupiscence sprang from Adam's disobedience and, being transmitted to us, can be removed only by Christ. It is shown, also, that Julian himself confesses lust to be evil, inasmuch as he speaks of remedies against it, wishes it to be bridled, and speaks of the continent waging a glorious warfare. The fourth book follows the second book of Julian's work, and makes two chief contentions: that unbelievers have no true virtues, and that even the heathen recognize concupiscence as evil. It also argues that grace is not given according to merit, and yet is not to be confounded with fate; and explains the text that asserts that God wishes all men to be saved,' in the sense that all men' means all that are to be saved' since none are saved except by His will.  The fifth book, in like manner, follows Julian's third book, and treats of such subjects as these: that it is due to sin that any infants are lost; that shame arose in our first parents through sin; that sin can well be the punishment of preceding sin; that concupiscence is always evil, even in those who do not assent to it; that true marriage may exist without intercourse; that the "flesh" of Christ differs from the "sinful flesh" of other men; and the like. In the sixth book, Julian's fourth book is followed, and original sin is proved from the baptism of infants, the teaching of the apostles, and the rites of exorcism and exsufflation incorporated in the form of baptism. Then, by the help of the illustration drawn from the olive and the oleaster, it is explained how Christian parents can produce unregenerate offspring; and the originally voluntary character of sin is asserted, even though it now comes by inheritance.
After the completion of this important work, there succeeded a lull in the controversy, of some years duration; and the calm refutation of Pelagianism and exposition of Christian grace, which Augustin gave in his Enchiridion,  might well have seemed to him his closing word on this all-absorbing subject. But he had not yet given the world all he had in treasure for it, and we can rejoice in the chance that five or six years afterwards drew from him a renewed discussion of some of the more important aspects of the doctrine of grace. The circumstances which brought this about are sufficiently interesting in themselves, and open up to us an unwonted view into the monastic life of the times. There was an important monastery at Adrumetum, the metropolitan city of the province of Byzacium,  from which a monk named Florus went out on a journey of charity to his native country of Uzalis about 426. On the journey he met with Augustin's letter to Sixtus,  in which the doctrines of gratuitous and prevenient grace were expounded. He was much delighted with it, and, procuring a copy, sent it back to his monastery for the edification of his brethren, while he himself went on to Carthage. At the monastery, the letter created great disturbance: without the knowledge of the abbot, Valentinus, it was read aloud to the monks, many of whom were unskilled in theological questions; and some five or more were greatly offended, and declared that free will was destroyed by it. A secret strife arose among the brethren, some taking extreme grounds on both sides. Of all this, Valentinus remained ignorant until the return of Florus, who was attacked as the author of all the trouble, and who felt it his duty to inform the abbot of the state of affairs. Valentinus applied first to the bishop, Evodius, for such instruction as would make Augustin's letter clear to the most simple. Evodius replied, praising their zeal and deprecating their contentiousness, and explaining that Adam had full free will, but that it is now wounded and weak, and Christ's mission was as a physician to cure and recuperate it. "Let them read," is his prescription, "the words of God's elders....And when they do not understand, let them not quickly reprehend, but pray to understand." This did not, however, cure the malecontents, and the holy presbyter Sabrinus was appealed to, and sent a book with clear interpretations. But neither was this satisfactory; and Valentinus, at last, reluctantly consented that Augustin himself should be consulted,—fearing, he says, lest by making inquiries he should seem to waver about the truth. Two members of the community were consequently permitted to journey to Hippo, but they took with them no introduction and no commendation from their abbot. Augustin, nevertheless, received them without hesitation, as they bore themselves with too great simplicity to allow him to suspect them of deception. Now we get a glimpse of life in the great bishop's monastic home. The monks told their story, and were listened to with courtesy and instructed with patience; and, as they were anxious to get home before Easter, they received a letter for Valentinus  in which Augustin briefly explains the nature of the misapprehension that had arisen, and points out that both grace and free will must be defended, and neither so exaggerated as to deny the other. The letter of Sixtus, he explains, was written against the Pelagians, who assert that grace is given according to merit, and briefly expounds the true doctrine of grace as necessarily gratuitous and therefore prevenient. When the monks were on the point of starting home, they were joined by a third companion from Adrumetum, and were led to prolong their visit. This gave him the opportunity he craved for their fuller instruction: he read with them and explained to them not only his letter to Sixtus, from which the strife had risen, but much of the chief literature of the Pelagian controversy,  copies of which also were made for them to take home with them; and when they were ready to go, he sent by them another and longer letter to Valentinus, and placed in their hands a treatise composed for their especial use, which, moreover, he explained to them. This longer letter is essentially an exhortation "to turn aside neither to the right hand nor to the left,"—neither to the left hand of the Pelagian error of upholding free will in such a manner as to deny grace, nor to the right hand of the equal error of so upholding grace as if we might yield ourselves to evil with impunity. Both grace and free will are to be proclaimed; and it is true both that grace is not given to merits, and that we are to be judged at the last day according to our works. The treatise which Augustin composed for a fuller exposition of these doctrines is the important work On Grace and Free Will. After a brief introduction, explaining the occasion of his writing, and exhorting the monks to humility and teachableness before God's revelations (1), Augustin begins by asserting and proving the two propositions that the Scriptures clearly teach that man has free will (2-5), and, as clearly, the necessity of grace for doing any good (6-9). He then examines the passages which the Pelagians claim as teaching that we must first turn to God, before He visits us with His grace (10-11), and then undertakes to show that grace is not given to merit (12 sq.), appealing especially to Paul's teaching and example, and replying to the assertion that forgiveness is the only grace that is not given according to our merits (15-18), and to the query, "How can eternal life be both of grace and of reward?" (19-21). The nature of grace, what it is, is next explained (22 sq.). It is not the law, which gives only knowledge of sin (22-24), nor nature, which would render Christ's death needless (25), nor mere forgiveness of sins, as the Lord's Prayer (which should be read with Cyprian's comments on it) is enough to show (26). Nor will it do to say that it is given to the merit of a good will, thus distinguishing the good work which is of grace from the good will which precedes grace (27-30); for the Scriptures oppose this, and our prayers for others prove that we expect God to be the first mover, as indeed both Scripture and experience prove that He is. It is next shown that both free will and grace are concerned in the heart's conversion (31-32), and that love is the spring of all good in man (33-40), which, however, we have only because God first loved us (38), and which is certainly greater than knowledge, although the Pelagians admit only the latter to be from God (40). God's sovereign government of men's wills is then proved from Scripture (41-43), and the wholly gratuitous character of grace is illustrated (44), while the only possible theodicy is found in the certainty that the Lord of all the earth will do right. For, though no one knows why He takes one and leaves another, we all know that He hardens judicially and saves graciously,—that He hardens none who do not deserve hardening, but none that He saves deserve to be saved (45). The treatise closes with an exhortation to its prayerful and repeated study (46).
The one request that Augustin made, on sending this work to Valentinus, was that Florus, through whom the controversy had arisen, should be sent to him, that he might converse with him and learn whether he had been misunderstood, or himself had misunderstood Augustin. In due time Florus arrived at Hippo, bringing a letter  from Valentinus which addresses Augustin as "Lord Pope" (domine papa), thanks him for his "sweet" and "healing" instruction, and introduces Florus as one whose true faith could be confided in. It is very clear, both from Valentinus' letter and from the hints that Augustin gives, that his loving dealing with the monks had borne admirable fruit: "none were cast down for the worse, some were built up for the better."  But it was reported to him that some one at the monastery had objected to the doctrine he had taught them, that "no man ought, then, to be rebuked for not keeping God's commandments; but only God should be besought that he might keep them."  In other words, it was said that if all good was, in the last resort, from God's grace, man ought not to be blamed for not doing what he could not do, but God ought to be besought to do for man what He alone could do: we ought, in a word, to apply to the source of power. This occasioned the composition of yet another treatise On Rebuke and Grace,  the object of which was to explain the relations of grace to human conduct, and especially to make it plain that the sovereignty of God's grace does not supersede our duty to ourselves or our fellow-men. It begins by thanking Valentinus for his letter and for sending Florus (whom Augustin finds well instructed in the truth), thanking God for the good effect of the previous book, and recommending its continued study, and then by briefly expounding the Catholic faith concerning grace, free-will, and the law (1-2). The general proposition that is defended is that the gratuitous sovereignty of God's grace does not supersede human means for obtaining and continuing it (3 sq.). This is shown by the apostle's example, who used all human means for the prosecution of his work, and yet confessed that it was "God that gave the increase" (3). Objections are then answered (4 sq.),—especially the great one that "it is not my fault if I do not do what I have not received grace for doing" (6); to which Augustin replies (7-10), that we deserve rebuke for our very unwillingness to be rebuked, that on the same reasoning the prescription of the law and the preaching of the gospel would be useless, that the apostle's example opposes such a position, and that our consciousness witnesses that we deserve rebuke for not persevering in the right way. From this point an important discussion arises, in this interest, of the gift of perseverance (11-19), and of God's election (20-24); the teaching being that no one is saved who does not persevere, and all that are predestinated or "called according to the purpose" (Augustin's phrase for what we should call "effectual calling") will persevere, and yet that we co-operate by our will in all good deeds, and deserve rebuke if we do not. Whether Adam received the gift of perseverance, and, in general, the difference between the grace given to him (which was that grace by which he could stand) and that now given to God's children (which is that grace by which we are actually made to stand), are next discussed (26-38), with the result of showing the superior greatness of the gifts of grace now to those given before the fall. The necessity of God's mercy at all times, and our constant dependence on it, are next vigorously asserted (39-42); even in the day of judgment, if we are not judged "with mercy" we cannot be saved (41). The treatise is brought to an end by a concluding application of the whole discussion to the special matter in hand, rebuke (43-49). Seeing that rebuke is one of God's means of working out his gracious purposes, it cannot be inconsistent with the sovereignty of that grace; for, of course, God predestinates the means with the end (43). Nor can we know, in our ignorance, whether our rebuke is, in any particular case, to be the means of amendment or the ground of greater condemnation. How dare we, then, withhold it? Let it be, however, graduated to the fault, and let us always remember its purpose (46-48). Above all, let us not dare hold it back, lest we hold back from our brother the means of his recovery, and, as well, disobey the command of God (49).
It was not long afterwards (about 427) when Augustin was called upon to attempt to reclaim a Carthaginian brother, Vitalis by name, who had been brought to trial on the charge of teaching that the beginning of faith was not the gift of God, but the act of man's own free will (ex propria voluntatis). This was essentially the semi-Pelagian position which was subsequently to make so large a figure in history; and Augustin treats it now as necessarily implying the basal idea of Pelagianism. In the important letter which he sent to Vitalis,  he first argues that his position is inconsistent with the prayers of the church. He, Augustin, prays that Vitalis may come to the true faith; but does not this prayer ascribe the origination of right faith to God? The Church so prays for all men: the priest at the altar exhorts the people to pray God for unbelievers, that He may convert them to the faith; for catechumens, that He may breathe into them a desire for regeneration; for the faithful, that by His aid they may persevere in what they have begun: will Vitalis refuse to obey these exhortations, because, forsooth, faith is of free will and not of God's gift? Nay, will a Carthaginian scholar array himself against Cyprian's exposition of the Lord's Prayer? for he certainly teaches that we are to ask of God what Vitalis says is to be had of ourselves. We may go farther: it is not Cyprian, but Paul, who says, "Let us pray to God that we do no evil" (2 Corinthians 13:7); it is the Psalmist who says, "The steps of man are directed by God" (Psalm 36:23). "If we wish to defend free will, let us not strive against that by which it is made free. For he who strives against grace, by which the will is made free for refusing evil and doing good, wishes his will to remain captive. Tell us, I beg you, how the apostle can say, We give thanks to the Father who made us fit to have our lot with the saints in light, who delivered us from the power of darkness, and translated us into the kingdom of the Son of His love' (Colossians 1:12, 13), if not He, but itself, frees our choice? It is, then, a false rendering of thanks to God, as if He does what He does not do; and he has erred who has said that He makes us fit, etc.' The grace of God,' therefore, does not consist in the nature of free-will, and in law and teaching, as the Pelagian perversity dreams; but it is given for each single act by His will, concerning whom it is written,"—quoting Psalm 67:10. About the middle of the letter, Augustin lays down twelve propositions against the Pelagians, which are important as communicating to us what he thought, at the end of the controversy, were the chief points in dispute. "Since, therefore," he writes, "we are catholic Christians: 1. We know that new-born children have not yet done anything in their own lives, good or evil, neither have they come into the miseries of this life according to the deserts of some previous life, which none of them can have had in their own persons; and yet, because they are born carnally after Adam, they contract the contagion of ancient death, by the first birth, and are not freed from the punishment of eternal death (which is contracted by a just condemnation, passing over from one to all), except they are by grace born again in Christ.2. We know that the grace of God is given neither to children nor to adults according to our deserts.3. We know that it is given to adults for each several act.4. We know that it is not given to all men; and to those to whom it is given, it is not only not given according to the merits of works, but it is not even given to them according to the merits of their will; and this is especially apparent in children.5. We know that to those to whom it is given, it is given by the gratuitous mercy of God.6. We know that to those to whom it is not given, it is not given by the just judgment of God.7. We know that we shall all stand before the tribunal of Christ, and each shall receive according to what he has done through the body,—not according to what he would have done, had he lived longer,—whether good or evil.8. We know that even children are to receive according to what they have done through the body, whether good or evil. But according to what "they have done" not by their own act, but by the act of those by whose responses for them they are said both to renounce the Devil and to believe in God, wherefore they are counted among the number of the faithful, and have part in the statement of the Lord when He says, "Whosoever shall believe and be baptized, shall be saved." Therefore also, to those who do not receive this sacrament, belongs what follows, "But whosoever shall not have believed, shall be damned" (Mark 16:16). Whence these too, as I have said, if they die in that early age, are judged, of course, according to what they have done through the body, i.e., in the time in which they were in the body, when they believe or do not believe by the heart and mouth of their sponsors, when they are baptized or not baptized, when they eat or do not eat the flesh of Christ, when they drink or do not drink His blood,—according to those things, then, which they have done through the body, not according to those which, had they lived longer, they would have done.9. We know that blessed are the dead that die in the Lord; and that what they would have done had they lived longer, is not imputed to them.10. We know that those that believe, with their own heart, in the Lord, do so by their own free will and choice.11. We know that we who already believe act with right faith towards those who do not wish to believe, when we pray to God that they may wish it.12. We know that for those who have believed out of this number, we both ought and are rightly and truly accustomed to return thanks to God, as for his benefits." Certainly such a body of propositions commends their author to us as Christian both in head and heart: they are admirable in every respect; and even in the matter of the salvation of infants, where he had not yet seen the light of truth, he expresses himself in a way as engaging in its hearty faith in God's goodness as it is honorable in its loyalty to what he believed to be truth and justice. Here his doctrine of the Church ran athwart and clouded his view of the reach of grace; but we seem to see between the lines the promise of the brighter dawn of truth that was yet to come. The rest of the epistle is occupied with an exposition and commendation of these propositions, which ranks with the richest passages of the anti-Pelagian writings, and which breathes everywhere a yearning for his correspondent which we cannot help hoping proved salutary to his faith.
It is not without significance, that the error of Vitalis took a semi-Pelagian form. Pure Pelagianism was by this time no longer a living issue. Augustin was himself, no doubt, not yet done with it. The second book of his treatise On Marriage and Concupiscence, which seems to have been taken to Italy by Alypius, in 421, received at once the attention of Julian, and was elaborately answered by him, during that same year, in eight books addressed to Florus. But Julian was now in Cilicia, and his book was slow in working its way westward. It was found at Rome by Alypius, apparently in 427 or 428, and he at once set about transcribing it for his friend's use. An opportunity arising to send it to Africa before it was finished, he forwarded to Augustin the five books that were ready, with an urgent request that they should receive his immediate attention, and a promise to send the other three as soon as possible. Augustin gives an account of his progress in his reply to them in a letter written to Quodvultdeus, apparently in 428.  This deacon was urging Augustin to give the Church a succinct account of all heresies; and Augustin excuses himself from immediately undertaking that task by the press of work on his hands. He was writing his Retractations, and had already finished two books of them, in which he had dealt with two hundred and thirty-two works. His letters and homilies remained and he had given the necessary reading to many of the letters. Also, he tells his correspondent, he was engaged on a reply to the eight books of Julian's new work. Working night and day, he had already completed his response to the first three of Julian's books, and had begun on the fourth while still expecting the arrival of the last three which Alypius had promised to send. If he had completed the answer to the five books of Julian which he already had in hand, before the other three reached him, he might begin the work which Quodvultdeus so earnestly desired him to undertake. In due time, whatever may have been the trials and labours that needed first to be met, the desired treatise On Heresies was written (about 428), and the eighty-eighth chapter of it gives us a welcome compressed account of the Pelagian heresy, which may be accepted as the obverse of the account of catholic truth given in the letter to Vitalis.  But the composition of this work was not the only interruption which postponed the completion of the second elaborate work against Julian. It was in the providence of God that the life of this great leader in the battle for grace should be prolonged until he could deal with semi-Pelagianism also. Information as to the rise of this new form of the heresy at Marseilles and elsewhere in Southern Gaul was conveyed to Augustin along with entreaties, that, as "faith's great patron," he would give his aid towards meeting it, by two laymen with whom he had already had correspondence,—Prosper and Hilary.  They pointed out  the difference between the new party and thorough-going Pelagianism; but, at the same time, the essentially Pelagianizing character of its formative elements. Its representatives were ready, as a rule, to admit that all men were lost in Adam, and no one could recover himself by his own free will, but all needed God's grace for salvation. But they objected to the doctrines of prevenient and of irresistible grace; and asserted that man could initiate the process of salvation by turning first to God, that all men could resist God's grace, and no grace could be given which they could not reject, and especially they denied that the gifts of grace came irrespective of merits, actual or foreseen. They said that what Augustin taught as to the calling of God's elect according to His own purpose was tantamount to fatalism, was contrary to the teaching of the fathers and the true Church doctrine, and, even if true, should not be preached, because of its tendency to drive men into indifference or despair. Hence, Prosper especially desired Augustin to point out the dangerous nature of these views, and to show that prevenient and co-operating grace is not inconsistent with free will, that God's predestination is not founded on foresight of receptivity in its objects, and that the doctrines of grace may be preached without danger to souls.
Augustin's answer to these appeals was a work in two books, On the Predestination of the Saints, the second book of which is usually known under the separate title of The Gift of Perseverance. The former book begins with a careful discrimination of the position of his new opponents: they have made a right beginning in that they believe in original sin, and acknowledge that none are saved from it save by Christ, and that God's grace leads men's wills, and without grace no one can suffice for good deeds. These things will furnish a good starting-point for their progress to an acceptance of predestination also (1-2). The first question that needs discussion in such circumstances is, whether God gives the very beginnings of faith (3 sq.); since they admit that what Augustin had previously urged sufficed to prove that faith was the gift of God so far as that the increase of faith was given by Him, but not so far but that the beginning of faith may be understood to be man's, to which, then, God adds all other gifts (compare 43). Augustin insists that this is no other than the Pelagian assertion of grace according to merit (3), is opposed to Scripture (4-5), and begets arrogant boasting in ourselves (6). He replies to the objection that he had himself once held this view, by confessing it, and explaining that he was converted from it by 1 Corinthians 4:7, as applied by Cyprian (7-8), and expounds that verse as containing in its narrow compass a sufficient answer to the present theories (9-11). He answers, further, the objection that the apostle distinguishes faith from works, and works alone are meant in such passages, by pointing to John 6:28, and similar statements in Paul (12-16). Then he answers the objection that he himself had previously taught that God acted on foresight of faith, by showing that he was misunderstood (17-18). He next shows that no objection lies against predestination that does not lie with equal force against grace (19-22),—since predestination is nothing but God's foreknowledge of and preparation for grace, and all questions of sovereignty and the like belong to grace. Did God not know to whom he was going to give faith (19)? or did he promise the results of faith, works, without promising the faith without which, as going before, the works were impossible? Would not this place God's fulfilment of his promise out of His power, and make it depend on man (20)? Why are men more willing to trust in their weakness than in God's strength? do they count God's promises more uncertain than their own performance (22)? He next proves the sovereignty of grace, and of predestination, which is but the preparation for grace, by the striking examples of infants, and, above all, of the human nature of Christ (23-31), and then speaks of the twofold calling, one external and one "according to purpose,"—the latter of which is efficacious and sovereign (32-37). In closing, the semi-Pelagian position is carefully defined and refuted as opposed, alike with the grosser Pelagianism, to the Scriptures of both Testaments (38-42).
The purpose of the second book, which has come down to us under the separate title of On the Gift of Perseverance, is to show that that perseverance which endures to the end is as much of God as the beginning of faith, and that no man who has been "called according to God's purpose," and has received this gift, can fall from grace and be lost. The first half of the treatise is devoted to this theme (1-33). It begins by distinguishing between temporary perseverance, which endures for a time, and that which continues to the end (1), and affirms that the latter is certainly a gift of God's grace, and is, therefore, asked from God which would otherwise be but a mocking petition (2-3). This, the Lord's Prayer itself might teach us, as under Cyprian's exposition it does teach us,—each petition being capable of being read as a prayer for perseverance (4-9). Of course, moreover, it cannot be lost, otherwise it would not be "to the end." If man forsakes God, of course it is he that does it, and he is doubtless under continual temptation to do so; but if he abides with God, it is God who secures that, and God is equally able to keep one when drawn to Him, as He is to draw him to Him (10-15). He argues anew at this point, that grace is not according to merit, but always in mercy; and explains and illustrates the unsearchable ways of God in His sovereign but merciful dealing with men (16-25), and closes this part of the treatise by a defence of himself against adverse quotations from his early work on Free Will, which he has already corrected in his Retractations. The second half of the book discusses the objections that were being urged against the preaching of predestination (34-62), as if it opposed and enervated the preaching of the Gospel. He replies that Paul and the apostles, and Cyprian and the fathers, preached both together; that the same objections will lie against the preaching of God's foreknowledge and grace itself, and, indeed, against preaching any of the virtues, as, e.g., obedience, while declaring them God's gifts. He meets the objections in detail, and shows that such preaching is food to the soul, and must not be withheld from men; but explains that it must be given gently, wisely, and prayerfully. The whole treatise ends with an appeal to the prayers of the Church as testifying that all good is from God (63-65), and to the great example of unmerited grace and sovereign predestination in the choice of one human nature without preceding merit, to be united in one person with the Eternal Word,—an illustration of his theme of the gratuitous grace of God which he is never tired of adducing (66-67).
These books were written in 428-429, and after their completion the unfinished work against Julian was resumed. Alypius had sent the remaining three books, and Augustin slowly toiled on to the end of his reply to the sixth book. But he was to be interrupted once more, and this time by the most serious of all interruptions. On the 28th of August, 430, with the Vandals thundering at the gates of Hippo, full of good works and of faith, he turned his face away from the strifes—whether theological or secular—of earth, and entered into rest with the Lord whom he loved. The last work against Julian was already one of the most considerable in size of all his books; but it was never finished, and retains until to-day the significant title of The Unfinished Work. Augustin had hesitated to undertake this work, because he found Julian's arguments too silly either to deserve refutation, or to afford occasion for really edifying discourse. And certainly the result falls below Augustin's usual level, though this is not due, as is so often said, to failing powers and great age; for nothing that he wrote surpasses in mellow beauty and chastened strength the two books, On the Predestination of the Saints, which were written after four books of this work were completed. The plan of the work is to state Julian's arguments in his own words, and follow it with his remarks; thus giving it something of the form of a dialogue. It follows Julian's work, book by book. The first book states and answers certain calumnies which Julian had brought against Augustin and the catholic faith on the ground of their confession of original sin. Julian had argued, that, since God is just, He cannot impute another's sins to innocent infants; since sin is nothing but evil will, there can be no sin in infants who are not yet in the use of their will; and, since the freedom of will that is given to man consists in the capacity of both sinning and not sinning, free will is denied to those who attribute sin to nature. Augustin replies to these arguments, and answers certain objections that are made to his work On Marriage and Concupiscence, and then corrects Julian's false explanations of certain Scriptures from John 8. Romans 6. vii., and 2 Timothy. he second book is a discussion of Romans 5:12, which Julian had tried, like the other Pelagians, to explain by the "imitation" of Adam's bad example. The third book examines the abuse by Julian of certain Old-Testament passages—in Deuteronomy 24. 2 Kings 14. Ezekiel 18.-- in his effort to show that God does not impute the father's sins to the children; as well as his similar abuse of Hebrews 11.The charge of Manicheism, which was so repetitiously brought by Julian against the catholics, is then examined and refuted. The fourth book treats of Julian's strictures on Augustin's On Marriage and Concupiscence ii.4-11, and proves from 1 John 2:16 that concupiscence is evil, and not the work of God, but of the Devil. He argues that the shame that accompanies it is due to its sinfulness, and that there was none of it in Christ; also, that infants are born obnoxious to the first sin, and proves the corruption of their origin from Wisd. x.10, 11. The fifth book defends On Marriage and Concupiscence ii.12 sq., and argues that a sound nature could not have shame on account of its members, and the need of regeneration for what is generated by means of shameful concupiscence. Then Julian's abuse of 1 Corinthians 15. Romans 5. Matthew 7:17 and 33, with reference to On Marriage and Concupiscence ii.14, 20, 26, is discussed; and then the origin of evil, and God's treatment of evil in the world. The sixth book traverses Julian's strictures on On Marriage and Concupiscence ii.34 sq., and argues that human nature was changed for the worse by the sin of Adam, and thus was made not only sinful, but the source of sinners; and that the forces of free will by which man could at first do rightly if he wished, and refrain from sin if he chose, were lost by Adam's sin. He attacks Julian's definition of free will as "the capacity for sinning and not sinning" (possibilitas peccandi et non peccandi); and proves that the evils of this life are the punishment of sin,—including, first of all, physical death. At the end, he treats of 1 Corinthians 15:22.
Although the great preacher of grace was taken away by death before the completion of this book, yet his work was not left incomplete. In the course of the next year (431) the Ecumenical Council of Ephesus condemned Pelagianism for the whole world; and an elaborate treatise against the pure Pelagianism of Julian was already in 430 an anachronism. Semi-Pelagianism was yet to run its course, and to work its way so into the heart of a corrupt church as not to be easily displaced; but Pelagianism was to die with the first generation of its advocates. As we look back now through the almost millennium and a half of years that has intervened since Augustin lived and wrote, it is to his Predestination of the Saints,—a completed, and well-completed, treatise,—and not to The Unfinished Work, that we look as the crown and completion of his labours for grace.

Epistle 217.  Epistle 224.  The account given of Pelagianism is as follows: "They are in such degree enemies of the grace of God, by which we have been predestined into the adoption of sons by Jesus Christ unto Himself (Ephesians 1:5), and by which we are delivered from the power of darkness so as to believe in Him, and be translated into His kingdom (Colossians 1:13)--wherefore He says, No man comes to Me, except it be given him of My Father' (John 6:66)--and by which love is shed abroad in our hearts (Romans 5:5), so that faith may work by love: that they believe that man is able, without it, to keep all the Divine commandments,--whereas, if this were true, it would clearly be an empty thing that the Lord said, Without Me ye can do nothing' (John 15:5). When Pelagius was at length accused by the brethren, because he attributed nothing to the assistance of God's grace towards the keeping of His commandments, he yielded to their rebuke, so far as not to place this grace above free will, but with faithless cunning to subordinate it, saying that it was given to men for this purpose; viz., that they might be able more easily to fulfil by grace, what they were commanded to do by free will. By saying, that they might be able more easily,' he, of course, wished it to be believed that, although with more difficulty, nevertheless men were able without divine grace to perform the divine commands. But that grace of God, without which we can do nothing good, they say does not exist except in free will, which without any preceding merits our nature received from Him; and that He adds His aid only in that by His law and teaching we may learn what we ought to do, but not in that by the gift of His Spirit we may do what we have learned ought to be done. Accordingly, they confess that knowledge by which ignorance is banished is divinely given to us, but deny that love by which we may live a pious life is given; so that, forsooth, while knowledge, which, without love, puffeth up, is the gift of God, love itself, which edifieth so that knowledge may not puff up, is not the gift of God (1 Corinthians 8:11). They also destroy the prayers which the Church offers, whether for those that are unbelieving and resisting God's teaching, that they may be converted to God; or for the faithful, that faith may be increased in them, and they may persevere in it. For they contend that men do not receive these things from Him, but have them from ourselves, saying, that the grace of God, by which we are freed from impiety, is given according to our merits. Pelagius was compelled, no doubt, to condemn this by his fear of being condemned by the episcopal judgment in Palestine; but he is found to teach it still in his later writings. They also advanced so far as to say that the life of the righteous in this world is without sin, and the Church of Christ is perfected by them in this mortality, to the point of being entirely without spot or wrinkle (Ephesians 5:27); as if it were not the Church of Christ, that, in the whole world, cries to God, Forgive us our debts.' They also deny that children, who are carnally born after Adam, contract the contagion of ancient death from their first birth. For they assert that they are born so without any bond of original sin, that there is absolutely nothing that ought to be remitted to them in the second birth, yet they are to be baptized; but for this reason, that, adopted in regeneration, they may be admitted to the kingdom of God, and thus be translated from good into better,--not that they may be washed by that renovation from any evil of the old bond. For although they be not baptized, they promise to them, outside the kingdom of God indeed, but nevertheless, a certain eternal and blessed life of their own. They also say that Adam himself, even had he not sinned, would have died in the body, and that this death would not have come as a desert to a fault, but as a condition of nature. Certain other things also are objected to them, but these are the chief, and also either all, or nearly all, the others may be understood to depend on these."  Compare Epistles 225, 1, and 156. It is, of course, not certain that this is the same Hilary that wrote to Augustin from Sicily, but it seems probable.  In Letters 225 and 226.

 The account given of Pelagianism is as follows: "They are in such degree enemies of the grace of God, by which we have been predestined into the adoption of sons by Jesus Christ unto Himself (Ephesians 1:5), and by which we are delivered from the power of darkness so as to believe in Him, and be translated into His kingdom (Colossians 1:13)--wherefore He says, No man comes to Me, except it be given him of My Father' (John 6:66)--and by which love is shed abroad in our hearts (Romans 5:5), so that faith may work by love: that they believe that man is able, without it, to keep all the Divine commandments,--whereas, if this were true, it would clearly be an empty thing that the Lord said, Without Me ye can do nothing' (John 15:5).
