Chrysostom (349-407): [3.] But first it is worth while to hear what those who are infected with the Manichaean doctrines say here, who are both enemies to the truth and war against their own salvation. What then do these allege? By death here, they say, Paul means nothing else than our being in sin; and by resurrection, our being delivered from our sins. Seest thou how nothing is weaker than error? And how it is taken by its own wings, and needs not the warfare from without, but by itself it is pierced through? Consider, for instance, these men, how they too have pierced themselves through by their own statements. Since if this be death, and Christ did not take a body, as ye suppose, and yet died, He was in sin according to you. For I indeed say that He took unto Himself a body and His death, I say, was that of the flesh; but thou denying this, wilt be compelled to affirm the other. But if He was in sin, how saith He, “Which of you convinceth Me of sin?” and “The prince of this world cometh, and hath nothing in me?” (John 8:46; 14:30.) and again, “Thus it becometh Us to fulfill all righteousness?” (Matthew 3:15.) Nay, how did He at all die for sinners, if Himself were in sin? For he who dies for sinners ought himself to be without sin. Since if he himself also sin, how shall he die for other sinners? But if for others’ sins He died, He died being without sin: and if being without sin He died, He died — not the death of sin; for how could He being without sin? — but the death of the body **Wherefore also Paul did not simply say, “He died,” but added, “for our sins:” **both forcing these heretics against their will to the confession of His bodily death, and signifying also by this that before death He was without sin: for he that dies for others’ sins, it followeth must himself be without sin.
** Neither was he content with this, but added, “according to the Scriptures:” hereby both again making his argument credible, and intimating what kind of death he was speaking of: since it is the death of the body which the Scriptures everywhere proclaim. For, “they pierced My hands and My feet,” (Psalm 21:18.) saith He, and, “they shall look on Him Whom they pierced.” (John 19:37. Zechariah 12:10.) And many other instances, too not to name all one by one, partly in words and partly in types, one may see in them stored up, setting forth His slaughter in the flesh and that ** He was slain for our sins. For, “for the sins of my people,” saith one, “is He come to death: “and, the Lord delivered Him up for our sins: “and, “He was wounded for our transgressions.” (Isaiah 53) But if thou dost not endure the Old Testament, hear John crying out and declaring both, as well His slaughter in the body as the cause of it: thus, “Behold,” saith he, “the Lamb of God, Who taketh away the sin of the world:” (John 1:29.) and Paul saying, “For Him Who knew no sin, He made to be sin on our behalf, that we might become the righteousness of God in Him:” (2 Corinthians 5:21.) and again, “Christ redeemed us from the curse of the law, having become a curse for us:” (Galatians 3:13.) and again, “having put off from himself principalities and powers, He made a show of them openly, triumphing over them;” (Colossians 2:15.) and ten thousand other sayings to show what happened at His death in the body, and because of our sins. Yea, and Christ Himself saith, “for your sakes I sanctify Myself” and, “now the prince of this world hath been condemned;” showing that having no sin he was slain.
