The Refutation of All Heresies

Since, then, we have explained the attempts (at a system) of the pseudo-gnostic Justinus, it appears likewise expedient in the following books to elucidate the opinions put forward in heresies following (in the way of consequence upon the doctrines of Justinus), and to leave not a single one of these (speculators) unrefuted. Our refutation will be accomplished by adducing the assertions made by them; such (at least of their statements) as are sufficient for making a public example (of these heretics). (And we shall attain our purpose), even though there should only be condemned the secret and ineffable (mysteries) practised among them, into which, silly mortals that they are, scarcely (even) with considerable labour are they initiated. Let us then see what also Simon affirms.
