Rom 7:4

“But "we are dead to the law by the body of Christ, that we should belong to another, to him who was raised from the dead" and was prophesied by the law: "that we might bear fruit unto God." Therefore "the law is holy and the commandment holy, righteous, and good." We, then, are dead to the law, that is to sin of which the law makes us aware; the law indicates it, it does not give rise to it; by telling us what we ought to do and prohibiting what we ought not to do, the law shows up the sin which lies underneath "that sin may be manifest." But if marriage according to the law is sin, I do not know how anyone can say he knows God when he asserts that the command of God is sin. If the law is holy, marriage is holy. This mystery the apostle refers to Christ and the Church.”

“Moreover in the former passage he says, "You are dead to the law," not to marriage, "that you may belong to another who was raised from the dead," as Bride and Church. The Church must be chaste, both from inward thoughts contrary to the truth and from outward tempters, that is the adherents of the sects who would persuade her to commit fornication against her one husband, Almighty God, lest as the serpent deceived Eve, who is called Life, we too should be led to transgress the commandments by the lewd craftiness of the sects.”

“Whose grace, if not of that God from whom also came the law? Unless it be, forsooth, that the Creator intercalated His law for the mere purpose of producing some employment for the grace of a rival god, an enemy to Himself (I had almost said, a god unknown to Him), "that as sin had" in His own dispensation "reigned unto death, even so might grace reign through righteousness unto (eternal) life by Jesus Christ," His own antagonist! For this (I suppose it was, that) the law of the Creator had "concluded all under sin," and had brought in "all the world as guilty (before God)," and had "stopped every mouth," so that none could glory through it, in order that grace might be maintained to the glory of the Christ, not of the Creator, but of Marcion! I may here anticipate a remark about the substance of Christ, in the prospect of a question which will now turn up. For he says that "we are dead to the law." It may be contended that Christ's body is indeed a body, but not exactly flesh.”

“When we were in the flesh and living according to it, we were unable to serve the newness of the Spirit on account of those sins which the law itself, which was in our members, nourished in order that they might bear fruit to death.… But when Christ died for us and we died to sin along with him, we were set free by him from the law of sin in which we were held, and now we can serve the law of God in newness of Spirit and not in the dead form of the law.”

“Now it is not on this only he grounds his exhortation, but also on the superiority of this second husband. And so he proceeds: "that ye should be married to another, even to Him Who is raised from the dead." Then to prevent their saying, If we do not choose to live with another husband, what then? For the Law does not indeed make an adulteress of the widow who lives in a second marriage, but for all that it does not force her to live in it. Now that they may not say this, he shows that from benefits already conferred, it is binding on us to choose it: and this he lays down more clearly in other passages, where he says, "Ye are not your own;" and, "Ye are bought with a price;" and, "Be not ye the servants of men"; and again, "One died for all, that they which live should not henceforth live unto themselves, but unto Him which died for them." This is then what he here alludes to in the words, "By the Body." And next he exhorts to better hopes, saying, "That we should bring forth fruit unto God." For then, he means, ye brought forth fruit unto death, but now unto God.”

“The phrase "in order that we" should be read as: "and so we shall".… For Paul wants to say that once we have been established in this life we shall bear the fruits of righteousness for God, since we have been changed from our behavior under the law.It is most remarkable that Paul says that we have died not through baptism but through the body of Christ. For Adam was the beginning of this life, and Christ is the beginning of the life to come. So, just as in this life we have everything in common with Adam, so also in the next life we shall have everything in common with Christ, beginning with his resurrection. We are said to be a part of the Lord's body because we share this with him. So just as we have been metaphorically born again by baptism, Paul says that we have become a part of Christ's body by sharing in the resurrection which is typified by baptism.”

“If you have died, he says, then you are not under the law. For if a wife after the death of her husband is not subject to liability, then all the more is she free from the yoke of the law when she herself has died. Notice how wisely he proves that the law itself wants people to leave it. And so you also were freed from the law through the body of Christ, crucified for us. For the body was put to death for this very reason, that you might die to the law and be under the authority of another, who died for you and then rose again. For the law does not live after it has died, but Christ lives even after He died, so that you have no right to depart from Him who lives. And what is the benefit of this? "That we should bear fruit to God," that is, so that from that marriage in which we were united with Christ, we might bear children to God, that is, good works.”

“Then when he says, therefore, my brethren, he concludes to his main proposition, saying, therefore, my brethren, you also have died to the law, by the body of Christ, i.e., in becoming members of the body of Christ, dying and being buried with him, as stated above; you have died to the law in the sense that the obligation of the law ceases in you, so that you may belong to another, namely, Christ, in whom, through rising with him, you have received a new life. Hence you are held obliged not by the law of the former life but by the law of the new life. But this application seems awkward, because in the preceding example the man died and the woman remarried without obligation of the law. But here the one released from obligation is said to die. However, if we consider it another way, there is a parallel, because since marriage is between two, it makes no difference which one dies. In either case the law of marriage is taken away by death. Hence the obligation of the old law ceases in virtue of the death by which we die with Christ. Then he shows the utility of this liberation, when he says, that we may bear fruit. In regard to this he does three things: first, he mentions the utility, saying: that we may bear fruit to God. For if we have been made members of Christ and abide in Christ, we can bear fruit, i.e., good works, for the honor of God: as the branch cannot bear fruit by itself, unless it abides in the vine (John 15:4).”

“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.”
