Reply to Faustus the Manichaean

¹⁷ Further, what is said in the promise of the Paraclete shows that it cannot possibly refer to Manichæus, who came so many years after. For it is distinctly said by John, that the Holy Spirit was to come immediately after the resurrection and ascension of the Lord: "For the Spirit was not yet given, because that Jesus was not yet glorified." Now, if the reason why the Spirit was not given was, that Jesus was not glorified, He would necessarily be given immediately on the glorification of Jesus.

In the same way, the Cataphrygians said that they had received the promised Paraclete; and so they fell away from the Catholic faith, forbidding what Paul allowed, and condemning second marriages, which he made lawful. They turned to their own use the words spoken of the Spirit, "He shall lead you into all truth," as if, forsooth, Paul and the other apostles had not taught all the truth, but had left room for the Paraclete of the Cataphrygians. The same meaning they forced from the words of Paul: "We know in part, and we prophesy in part; but when that which is perfect has come, then that which is in part shall be done away;" making out that the apostle knew and prophesied in part, when he said, "Let him do what he will; if he marries, he sins not," and that this is done away by the perfection of the Phrygian Paraclete. And if they are told that they are condemned by the authority of the Church, which is the subject of such ancient promises, and is spread all over the world, they reply that this is in exact fulfillment of what is said of the Paraclete, that the world cannot receive Him. And are not those passages, "He shall lead you into all truth," and, "When that which is perfect has come, that which is in part shall be done away," and, "The world cannot receive Him," precisely those in which you find a prediction of Manichæus? And so every heresy arising under the name of the Paraclete will have the boldness to make an equally plausible application to itself of such texts. For there is no heresy but will call itself the truth; and the prouder it is, the more likely it will be to call itself perfect truth: and so it will profess to lead into all truth; and since that which is perfect has come by it, it will try to do away with the doctrine of the apostles, to which its own errors are opposed. And as the Church holds by the earnest admonition of the apostle, that "whoever preaches another gospel to you than that which you have received, let him be accursed;" when the heretical preacher begins to be pronounced accursed by all the world, will he not immediately exclaim, This is what is written, "The world cannot receive Him"?
