The Epistle of jude
1. Jude, the servant of Jesus Christ, and brother of James, to them that are sanctified by God the Father, and preserved in Jesus Christ, and called:
1. Judas Jesu Christi servus, frater autem Jacobi,, vocatis qui in Deo Patre sanctificati sunt, et in Jesu Christo custoditi,
2. Mercy unto you, and peace, and love, be multiplied.
2. Misericordia vobis et pax et dilectio augeatur.
1 Jude the servant of Jesus Christ. He calls himself the servant of Christ, not as the name applies to all the godly, but with respect to his apostleship; for they were deemed peculiarly the servants of Christ, who had some public office committed to them. And we know why the apostles were wont to give themselves this honorable name. Whosoever is not called, arrogates to himself presumptuously the right and authority of teaching. Then their calling was an evidence to the apostles, that they did not thrust themselves into their office through their own will. It was not, however, of itself sufficient to be appointed to their office, except they faithfully discharged it. And, no doubt, he who declares himself to be the servant of God, includes both these things, that is, that God is the bestower of the office which he exercises, and that he faithfully performs what has been committed to him. Many act falsely, and falsely boast to be what they are very far from being: we ought always to examine whether the reality corresponds with the profession.
And brother of James. He mentions a name more celebrated than his own, and more known to the churches. For though faithfulness of doctrine and authority do not depend on the names of mortal men, yet it is a confirmation to the faith, when the integrity of the man who undertakes the office of a teacher is made certain to us. Besides, the authority of James is not here brought forward as that of a private individual, but because he was counted by all the Church as one of the chief apostles of Christ. He was the son of Alpheus, as I have said elsewhere. Nay, this very passage is a sufficient proof to me against Eusebius and others, who say, that he was a disciple, named Oblias, [James,] mentioned by Luke, in Acts 15:13; Acts 21:18, who was more eminent than the apostles in the Church.  But there is no doubt but that Jude mentions here his own brother, because he was eminent among the apostles. It is, then, probable, that he was the person to whom the chief honor was conceded by the rest, according to what Luke relates.
To them that are sanctified by God the Father, or, to the called who are sanctified, etc.  By this expression, "the called," he denotes all the faithful, because the Lord has separated them for himself. But as calling is nothing else but the effect of eternal election, it is sometimes taken for it. In this place it makes but little difference in which way you take it; for he, no doubt, commends the grace of God, by which he has been pleased to choose them as his peculiar treasure. And he intimates that men do not anticipate God, and that they never come to him until he draws them.
Of the same he says that they were sanctified in God the Father, which may be rendered, "by God the Father." I have, however, retained the very form of the expression, that readers may exercise their own judgment. For it may be, that this is the sense, — that being profane in themselves, they had their holiness in God. But the way in which God sanctifies is, by regenerating us by his Spirit.
Another reading, which the Vulgate has followed, is somewhat harsh, "To the beloved (egapemenois) in God the Father." I therefore regard it as corrupt; and it is, indeed, found but in a few copies.
He further adds, that they were preserved in Jesus Christ. For we should be always in danger of death through Satan, and he might take us at any moment as an easy prey, were we not safe under the protection of Christ, whom the Father has given to be our guardian, so that none of those whom he has received under his care and shelter should perish.
Jude then mentions here a threefold blessing, or favor of God, with regard to all the godly, — that he has made them by his calling partakers of the gospel; that he has regenerated them, by his Spirit, unto newness of life; and that he has preserved them by the hand of Christ, so that they might not fall away from salvation.
2. Mercy to you. Mercy means nearly the same as grace in the salutations of Paul. Were any one to wish for a refined distinction, it may be said that grace is properly the effect of mercy; for there is no other reason why God has embraced us in love, but that he pitied our miseries. Love may be understood as that of God towards men, as well as that of men towards one another.  If it be referred to God, the meaning is, that it might increase towards them, and that the assurance of divine love might be daily more confirmed in their hearts. The other meaning is, however, not unsuitable, that God would kindle and confirm in them mutual love.
 Some have held, that James, mentioned in the forecited places in Acts, was not James the apostle, but another James, a disciple, and one of the seventy, who was also called Oblias: but this is not correct. -- Ed.  So Beza renders the words, "To the called, sanctified by God the Father, and preserved by Jesus Christ:" that is, to the effectually called, (as the word commonly means,) set apart and separated by God from the ungodly world, and kept by Christ, having been committed to his care and protection. -- Ed.  As mercy is that of God, so it is more consistent to consider "peace" and "love'' to be those of God: "may the mercy" of God, "and the peace" of God, "and the love" of God, "be increased (or multiplied) to you" -- Ed.
