John Chrysostom: Shun the Man Who Rejects Scripture

A Manichean comes and says, Matter is uncreated; say to him, In the beginning God made heaven and earth, and immediately you have overthrown all his conceit. But he does not believe the statement of Scripture, you retort. On these grounds also, then, shun and avoid him as a madman: anyone who does not believe in God who has manifested Himself, and instead represents truth as falsehood -- how does he not patently demonstrate his madness, his unbelief?
