Reply to Faustus the Manichaean

⁵ These things are not my conjectures, but are affirmed constantly by the apostle, with an emphasis sufficient to rouse the careless and to silence the gainsayers. "God," he says, "sent His Son in the likeness of sinful flesh, that by sin He might condemn sin in the flesh." Christ's flesh was not sinful, because it was not born of Mary by ordinary generation; but because death is the effect of sin, this flesh, in being mortal, had the likeness of sinful flesh. This is called sin in the following words, "that by sin He might condemn sin in the flesh." Again he says: "He has made Him to be sin for us who knew no sin, that we might be made the righteousness of God in Him." Why should not Moses call accursed what Paul calls sin? In this prediction the prophet claims a share with the apostle in the reproach of the heretics. For whoever finds fault with the word cursed in the prophet, must find fault with the word sin in the apostle; for curse and sin go together.
