Of the Manicheans

These things are the principal of what they say and think. And they honour very especially the sun and moon, not as gods, but as the way by which it is possible to attain unto God. But when the divine virtue has been entirely separated off, they say that the exterior fire will fall, and burn up both itself and all else that is left of matter. Those of them who are better educated, and not unacquainted with Greek literature, instruct us from their own resources. From the ceremonies and mysteries, for instance: by Bacchus, who was cut out from the womb, is signified that the divine virtue is divided into matter by the Titans, as they say; from the poet's fable of the battle with the Giants, is indicated that not even they were ignorant of the rebellion of matter against God.

I indeed will not deny, that these things are not sufficient to lead away the minds of those who receive words without examining them, since the deception caused by discourse of this sort has drawn over to itself some of those who have pursued the study of philosophy with me; but in what manner I should approach the thing to examine into it, I am at a loss indeed. For their hypotheses do not proceed by any legitimate method, so that one might institute an examination in accordance with these; neither are there any principles of demonstrations, so that we may see what follows on these; but theirs is the rare discovery of those who are simply said to philosophize.

These men, taking to themselves the Old and New Scriptures, though they lay it down that these are divinely inspired, draw their own opinions from thence; and then only think they are refuted, when it happens that anything not in accordance with these is said or done by them. And what to those who philosophize after the manner of the Greeks, as respects principles of demonstration, are intermediate propositions; this, with them, is the voice of the prophets. But here, all these things being eliminated, and since those matters, which I before mentioned, are put forward without any demonstration, and since it is necessary to give an answer in a rational way, and not to put forward other things more plausible, and which might prove more enticing, my attempt is rather troublesome, and on this account the more arduous, because it is necessary to bring forward arguments of a varied nature.

For the more accurate arguments will escape the observation of those who have been convinced beforehand by these men without proof, if, when it comes to persuasion, they fall into the same hands. For they imagine that they proceed from like sources. There is, therefore, need of much and great diligence, and truly of God, to be the guide of our argument.
