Book XIII.
Faustus asserts that even if the Old Testament could be shown to contain predictions, it would be of interest only to the Jews, pagan literature subserving the same purpose for Gentiles. Augustin shows the value of prophesy for Gentiles and Jews alike.
1. said: We are asked how we worship Christ when we reject the prophets, who declared the promise of His advent. It is doubtful whether, on examination, it can be shown that the Hebrew prophets foretold our Christ, that is, the Son of God. But were it so, what does it matter to us? If these testimonies of the prophets that you speak of were the means of converting any one from Judaism to Christianity, and if he should afterwards neglect these prophets, he would certainly be in the wrong, and would be chargeable with ingratitude. But we are by nature Gentiles, of the uncircumcision; as Paul says, born under another law. Those whom the Gentiles call poets were our first religious teachers, and from them we were afterwards converted to Christianity. We did not first become Jews, so as to reach Christianity through faith in their prophets; but were attracted solely by the fame, and the virtues, and the wisdom of our liberator Jesus Christ. If I were still in the religion of my fathers, and a preacher were to come using the prophets as evidence in favor of Christianity, I should think him mad for attempting to support what is doubtful by what is still more doubtful to a Gentile of another religion altogether. He would require first to persuade me to believe the prophets, and then through the prophets to believe Christ. And to prove the truth of the prophets, other prophets would be necessary. For if the prophets bear witness to Christ, who bears witness to the prophets? You will perhaps say that Christ and the prophets mutually support each other. But a Pagan, who has nothing to do with either, would believe neither the evidence of Christ to the prophets, nor that of the prophets to Christ. If the Pagan becomes a Christian, he has to thank his own faith, and nothing else. Let us, for the sake of illustration, suppose ourselves conversing with a Gentile inquirer. We tell him to believe in Christ, because He is God. He asks for proof. We refer him to the prophets. He asks, What prophets? We reply, The Hebrew. He smiles, and says that he does not believe them. We remind him that Christ testifies to them. He replies, laughing, that we must first make him believe in Christ. The result of such a conversation is that we are silenced, and the inquirer departs, thinking us more zealous than wise. Again, I say, the Christian Church, which consists more of Gentiles than of Jews, can owe nothing to Hebrew witnesses. If, as is said, any prophecies of Christ are to be found in the Sibyl, or in Hermes, called Trismegistus, or Orpheus, or any heathen poet, they might aid the faith of those who, like us, are converts from heathenism to Christianity. But the testimony of the Hebrews is useless to us before conversion, for then we cannot believe them; and superfluous after, for we believe without them.
2. replied: After the long reply of last book, a short answer may suffice here. To one who has read that reply, it must seem insanity in Faustus to persist in denying that Christ was foretold by the Hebrew prophets, when the Hebrew nation was the only one in which the name Christ had a peculiar sacredness as applied to kings and priests; in which sense it continued to be applied till the coming of Him whom those kings and priests typified. Where did the Manichæan learn the name of Christ? If from Manichæus, it is very strange that Africans, not to speak of others, should believe the Persian Manichæus, since Faustus finds fault with the Romans and Greeks, and other Gentiles, for believing the Hebrew prophets as belonging to another race. According to Faustus, the predictions of the Sibyl, or Orpheus, or any heathen poet, are more suitable for leading Gentiles to believe in Christ. He forgets that none of these are read in the churches, whereas the voice of the Hebrew prophets, sounding everywhere, draws swarms of people to Christianity. When it is so evident that men are everywhere led to Christ by the Hebrew prophets, it is great absurdity to say that those prophets are not suitable for the Gentiles.
