1 Peter 2:24-25
24. Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed.
24. Qui peccata nostra ipse pertulit in corpore suo super lignum, ut peccatis mortui, justitiae vivamus: cujus livori sanati estis.
25. For ye were as sheep going astray; but are now returned unto the Shepherd and Bishop of your souls.
25. Eratis enim tanquam oves errantes; sed conversi estis nunc ad Pastorem et Episcopum animarum vestrarum.
Had he commended nothing in Christ's death except as an example, it would have been very frigid: he therefore refers to a fruit much more excellent. There are then three things to be noticed in this passage. The first is, that Christ by his death has given us an example of patience; the second, that by his death he restored us to life; it hence follows, that we are so bound to him, that we ought cheerfully to follow his example. In the third place, he refers to the general design of his death, that we, being dead to sins, ought to live to righteousness. And all these things confirm his previous exhortation.
24 Who his own self bare our sins This form of speaking is fitted to set forth the efficacy of Christ's death. For as under the Law, the sinner, that he might be released from guilt, substituted a victim in his own place; so Christ took on himself the curse due to our sins, that he might atone for them before God. And he expressly adds, on the tree, because he could not offer such an expiation except on the cross. Peter, therefore, well expresses the truth, that Christ's death was a sacrifice for the expiation of our sins; for being fixed to the cross and offering himself a victim for us, he took on himself our sin and our punishment. Isaiah, from whom Peter has taken the substance of his doctrine, employs various forms of expression, — that he was smitten by God's hand for our sins, that he was wounded for our iniquities, that he was afflicted and broken for our sake, that the chastisement of our peace was laid on him. But Peter intended to set forth the same thing by the words of this verse, even that we are reconciled to God on this condition, because Christ made himself before his tribunal a surety and as one guilty for us, that he might suffer the punishment due to us.
This great benefit the Sophists in their schools obscure as much as they can; for they prattle that by the sacrifice of the death of Christ we are only freed after baptism from guilt, but that punishment is redeemed by satisfactions. But Peter, when he says that he bore our sins, means that not only guilt was imputed to him, but that he also suffered its punishment, that he might thus be an expiatory victim, according to that saying of the Prophet, "The chastisement of our peace was upon him." If they object and say, that this only avails before baptism, the context here disproves them, for the words are addressed to the faithful.
But this clause and that which follows, by whose stripes ye were healed, may be also applied to the subject in hand, that is, that it behoves us to bear on our shoulders the sins of others, not indeed to expiate for them, but only to bear them as a burden laid on us.
Being dead to sins  He had before pointed out another end, even an example of patience; but here, as it has been stated, it is made more manifest, that we are to live a holy and righteous life. The Scripture sometimes mentions both, that is, that the Lord tries us with troubles and adversities, that we might be conformed to the death of Christ, and also that the old man has been crucified in the death of Christ, that we might walk in newness of life. (Philippians 3:10; Romans 6:4.) At the same time, this end of which he speaks, differs from the former, not only as that which is general from what is particular; for in patience there is simply an example; but when he says that Christ suffered, that we being dead to sins should live to righteousness, he intimates that there is power in Christ's death to mortify our flesh, as Paul explains more fully in the sixth chapter of the Epistle to the Romans. For he has not only brought this great benefit to us, that God justifies us freely, by not imputing to us our sins; but he also makes us to die to the world and to the flesh, that we may rise again to a new life: not that one day makes complete this death; but wherever it is, the death of Christ is efficacious for the expiation of sins, and also for the mortification of the flesh.
25 For ye were as sheep This also has Peter borrowed from Isaiah, except that the Prophet makes it a universal statement,
"All we like sheep have gone astray." (Isaiah 53:6.)
But on the word sheep there is no particular stress; he indeed compares us to sheep, but the emphasis is on what the Prophet adds, when he says that every one had turned to his own way. The meaning then is, that we are all going astray from the way of salvation, and proceeding in the way of ruin, until Christ brings us back from this wandering.
And this appears still more evident from the clause which follows, but are now returned to the Shepherd, etc.;  for all who are not ruled by Christ, are wandering like lost sheep in the ways of error. Thus, then, is condemned the whole wisdom of the world, which does not submit to the government of Christ. But the two titles given here to Christ are remarkable, that he is the Shepherd and Bishop of souls There is then no cause to fear, but that he will faithfully watch over the safety of those who are in his fold and under his care. And it is his office to keep us safe both in body and soul; yet Peter mentions only souls, because this celestial Shepherd keeps us under his own spiritual protection unto eternal life.
 Or, "Being freed from sins:" apogenomenoi, being away from, having departed from, or, being removed from. Beza renders it "being separated from." Freedom from the power or dominion of sin seems more expressly to be intended, as the end of this freedom is, that we may live to righteousness; the end of forgiveness on the other hand is, that we may have peace with God. Beza, Estius, Grotis, and Scott, take this view of the sentence. The subject in hand is not the removal of guilt, but holiness of life, and Christ in his sufferings is set forth as the pattern to us. Then in what follows, our diseased state and our wandering from the right way, are the things referred to. Christ's death was intended to answer two great ends, -- to remove guilt and to remove or to destroy sin in us. The latter is the subject of this passage. -- Ed.  I would render the clause thus, "But you have been now restored," that is, from your wandering, "to the shepherd and the bishop (or, overseer) of your souls." Macknight thinks, that our Lord took the title of shepherd in order to shew that he is the person foretold in Ezekiel 34:23, and that Peter alludes, in calling him bishop or overseer, to the eleventh verse of that chapter, the latter clause of which, according to the Sept. is, "I will oversee them," (episkepsomai.) -- Ed.
