Therefore, my brethren, you also have become dead to the law by the body of Christ; that you should be married to another, even to him who is raised from the dead, that we should bring forth fruit unto God.

Ambrosiaster
AD 400
Since the Savior allowed the devil to crucify his body knowing that this was for us and against him, Paul says that we have been saved by the body of Christ. For to die to the law is to live to God, since the law rules over sinners. Therefore the one whose sins are forgiven dies to the law; this is what it means to be set free from the law. We receive this blessing through the body of Christ, for by giving up his body the Savior conquered death and condemned sin. The devil sinned against him when it killed him even though he was innocent and entirely without sin. For when the devil claims a man for himself because of sin, he is found to be guilty of the thing he accuses him of. Thus it happens that all who believe in Christ are delivered from the law, because sin has been condemned. For sin, which is of the devil, has been conquered by the body of Christ. Now he has no authority over those who belong to Christ, by whom he has been conquered. For because Christ was sinless yet was killed as if he were guilty, he conquered sin by sin—that is to say, he defeated the devil by his own sin. And what he allowed to get into the devil he condemned, thereby destroying the penalty which had been decreed because of the sin of Adam. When he rose again from the dead an image of new life was stamped upon those who believe in him, so that they cannot be bound by the second death. For this reason we have died to the law by the body of Christ. Thus whoever has not died to the law is still guilty, and whoever is guilty cannot escape the second death…. Whoever perseveres in the grace of Christ belongs to God and is worthy of the promised resurrection. Commentary on Paul’s Epistles.
