The Refutation of All Heresies: Book VI. 2The Ophites the Progenitors of Subsequent Heresies.

Whatever opinions, then, were entertained by those who derived the first principles (of their doctrine) from the serpent, and in process of time deliberately brought forward into public notice their tenets, we have explained in the book preceding this, (and) which is the fifth of the Refutation of Heresies. But now also I shall not be silent as regards the opinions of (heresiarchs) who follow these (Ophites in succession); nay, not one (speculation) will I leave unrefuted, if it is possible to remember all (their tenets), and the secret orgies of these (heretics) which one may fairly style orgies,--for they who propagate such audacious opinions are not far distant from the anger (of God),--that I may avail myself of the assistance of etymology.
