Book VI, Chapter 1

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.
