Chapter IV.—Docetic Doctrine Derived from the Greek Sophists. These (statements), therefore, I consider sufficient to properly-constituted minds for the purpose of attaining unto a knowledge of the complicated and unstable heresy of the Docetæ. (But) those who have propounded attempted arguments about inaccessible and incomprehensible Matter, have styled themselves Docetæ. Now, we consider that some of these are acting foolishly, we will not say in appearance, but in reality. At all events, we have proved that a beam from such matter is carried in the eye, if by any means they may be enabled to perceive it. If, however, they do not (discern it, our object is) that they should not make others blind. But the fact is, that the sophists of the Greeks in ancient times have previously devised, in many particulars, the doctrines of these (Docetæ), as it is possible for my readers (who take the trouble) to ascertain. These, then, are the opinions propounded by the Docetæ. As to what likewise, however, are the tenets of Monoïmus, we shall not be silent.
