To Florus 4.42

But I have shown that this desire naturally implanted in the sexes is not evil, since it belongs to God’s work. Accordingly, you must abandon either your impiety or your modesty. But why do I say this? “If the Ethiopian changes his skin or the leopard its spots” (Jeremiah 13:23), then you too will be washed clean of the Manichaean mysteries.
