Reply to Faustus the Manichaean

²⁹ Unless Christ had considered this Sabbath— which in your want of knowledge and of piety you laugh at— one of the prophecies written of Himself, He would not have borne such a testimony to it as He did. For when, as you say in praise of Christ, He suffered voluntarily, and so could choose His own time for suffering and for resurrection, He brought it about that His body rested from all its works on Sabbath in the tomb, and that His resurrection on the third day, which we call the Lord's day, the day after the Sabbath, and therefore the eighth, proved the circumcision of the eighth day to be also prophetical of Him.

For what does circumcision mean, but the eradication of the mortality which comes from our carnal generation? So the apostle says: "Putting off from Himself His flesh, He made a show of principalities and powers, triumphing over them in Himself." The flesh here said to be put off is that mortality of flesh on account of which the body is properly called flesh. The flesh is the mortality, for in the immortality of the resurrection there will be no flesh; as it is written, "Flesh and blood shall not inherit the kingdom of God."

You are accustomed to argue from these words against our faith in the doctrine of the resurrection of the body, which has already taken place in the Lord Himself. You keep out of view the following words, in which the apostle explains his meaning. To show what he here means by flesh, he adds, "Neither shall corruption inherit incorruption." For this body, which from its mortality is properly called flesh, is changed in the resurrection, so as to be no longer corruptible and mortal.

This is the apostle's statement, and not a supposition of ours, as his next words prove. "Lo" he says, "I show you a mystery: we shall all rise again, but we shall not all be changed. In a moment, in the twinkling of an eye, at the last trump; for the last trumpet shall sound, and the dead shall rise incorruptible, and we shall be changed. For this corruptible must put on incorruption, and this mortal must put on immortality." To put on immortality, the body puts off mortality.

This is the mystery of circumcision, which by the law took place on the eighth day; and on the eighth day, the Lord's day, the day after the Sabbath, was fulfilled in its true meaning by the Lord. Hence it is said, "Putting off His flesh, He made a show of principalities and powers." For by means of this mortality the hostile powers of hell ruled over us. Christ is said to have made a show or example of these, because in Himself, our Head, He gave an example which will be fully realized in the liberation of His whole body, the Church, from the power of the devil at the last resurrection.

This is our faith. And according to the prophetic declaration quoted by Paul, "The just shall live by faith." This is our justification. Even Pagans believe that Christ died. But only Christians believe that Christ rose again. "If you confess with your mouth," says the apostle, "that Jesus is the Lord, and believest in your heart that God raised Him from the dead, you shall be saved." Again, because we are justified by faith in Christ's resurrection, the apostle says, "He died for our offenses, and rose again for our justification." And because this resurrection by faith in which we are justified was prefigured by the circumcision of the eighth day, the apostle says of Abraham, with whom the observance began, "He received the sign of circumcision, a seal of the righteousness of faith." Circumcision, then, is one of the prophecies of Christ, written by Moses, of whom Christ said, "He wrote of me."

In the words of the Lord, "Woe unto you, scribes and Pharisees, hypocrites! For you compass sea and land to make one proselyte; and when he is made, you make him twofold more the child of hell than yourselves," it is not the circumcision of the proselyte which is meant, but his imitation of the conduct of the scribes and Pharisees, which the Lord forbids His disciples to imitate, when He says: "The scribes and Pharisees sit on Moses' seat: what they say unto you, do; but do not after their works; for they say, and do not." These words of the Lord teach us both the honor due to the teaching of Moses, in whose seat even bad men were obliged to teach good things, and the reason of the proselyte becoming a child of hell, which was not that he heard from the Pharisees the words of the law, but that he copied their example.

Such a circumcised proselyte might have been addressed in the words of Paul: "Circumcision verily profits, if you keep the law." His imitation of the Pharisees in not keeping the law made him a child of hell. And he was twofold more than they, probably because of his neglecting to fulfill what he voluntarily undertook, when, not being born a Jew, he chose to become a Jew.
