Calvin comments on Rom. 4:25-
Who was delivered for our offences, etc. He expands and illustrates more at large the doctrine to which I have just referred. It indeed greatly concerns us, not only to have our minds directed to Christ, but also to have it distinctly made known how he attained salvation for us. And though Scripture, when it treats of our salvation, dwells especially on the death of Christ, yet the Apostle now proceeds farther: for as his purpose was more explicitly to set forth the cause of our salvation, he mentions its two parts; and says, first, that our sins were expiated by the death of Christ, — and secondly, that by his resurrection was obtained our righteousness. But the meaning is, that when we possess the benefit of Christ’s death and resurrection, there is nothing wanting to the completion of perfect righteousness. By separating his death from his resurrection, he no doubt accommodates what he says to our ignorance; for it is also true that righteousness has been obtained for us by that obedience of Christ, which he exhibited in his death, as the Apostle himself teaches us in the following chapter. But as Christ, by rising from the dead, made known how much he had effected by his death, this distinction is calculated to teach us that our salvation was begun by the sacrifice, by which our sins were expiated, and was at length completed by his resurrection: for the beginning of righteousness is to be reconciled to God, and its completion is to attain life by having death abolished. Paul then means, that satisfaction for our sins was given on the cross: for it was necessary, in order that Christ might restore us to the Father’s favor, that our sins should be abolished by him; which could not have been done had he not on their account suffered the punishment, which we were not equal to endure. Hence Isaiah says, that the chastisement of our peace was upon him. (Isaiah 53:5.) But he says that he was delivered, and not, that he died; for expiation depended on the eternal goodwill of God, who purposed to be in this way pacified.
And was raised again for our justification. As it would not have been enough for Christ to undergo the wrath and judgment of God, and to endure the curse due to our sins, without his coming forth a conqueror, and without being received into celestial glory, that by his intercession he might reconcile God to us, the efficacy of justification is ascribed to his resurrection, by which death was overcome; not that the sacrifice of the cross, by which we are reconciled to God, contributes nothing towards our justification, but that the completeness of his favor appears more clear by his coming to life again.
But I cannot assent to those who refer this second clause to newness of life; for of that the Apostle has not begun to speak; and further, it is certain that both clauses refer to the same thing. For if justification means renovation, then that he died for our sins must be taken in the same sense, as signifying that he acquired for us grace to mortify the flesh; which no one admits. Then, as he is said to have died for our sins, because he delivered us from the evil of death by suffering death as a punishment for our sins; so he is now said to have been raised for our justification, because he fully restored life to us by his resurrection: for he was first smitten by the hand of God, that in the person of the sinner he might sustain the misery of sin; and then he was raised to life, that he might freely grant to his people righteousness and life. He therefore still speaks of imputative justification; and this will be confirmed by what immediately follows in the next chapter.
He has similar thoughts regarding 1 Cor. 15:4-
That Christ died, etc. See now more clearly whence he received it, for he quotes the Scriptures in proof. In the first place, he makes mention of the death of Christ, nay also of his burial, that we may infer, that, as he was like us in these things, he is so also in his resurrection. He has, therefore, died with us that we may rise with him. In his burial, too, the reality of the death in which he has taken part with us, is made more clearly apparent. Now there are many passages of Scripture in which Christ’s death and resurrection are predicted, but nowhere more plainly than in Isaiah 53, in Daniel 9:26, and in Psalm 22
For our sins That is, that by taking our curse upon him he might redeem us from it. For what else was Christ’s death, but a sacrifice for expiating our sins — what but a satisfactory penalty, by which we might be reconciled to God — what but the condemnation of one, for the purpose of obtaining forgiveness for us? He speaks also in the same manner in Romans 4:25, but in that passage, on the other hand, he ascribes it also to the resurrection as its effect — that it confers righteousness upon us; for as sin was done away through the death of Christ, so righteousness is procured through his resurrection. This distinction must be carefully observed, that we may know what we must look for from the death of Christ, and what from his resurrection. When, however, the Scripture in other places makes mention only of his death, let us understand that in those cases his resurrection is included in his death, but when they are mentioned separately, the commencement of our salvation is (as we see) in the one, and the consummation of it in the other.
