10 Again, as to the second production which proceeds from these [Æons who have been mentioned]—that, namely, of Homo and Ecclesia—their very fathers, falsely styled Gnostics, strive among themselves, each one seeking to make good his own opinions, and thus convicting themselves of being wicked thieves. They maintain that it is more suitable to [the theory of] production— as being, in fact, truth-like— that the Word was produced by man, and not man by the Word; and that man existed prior to the Word, and that this is really He who is God over all.
And thus it is, as I have previously remarked, that heaping together with a kind of plausibility all human feelings, and mental exercises, and formation of intentions, and utterances of words, they have lied with no plausibility at all against God. For while they ascribe the things which happen to men, and whatsoever they recognise themselves as experiencing, to the divine reason, they seem to those who are ignorant of God to make statements suitable enough. And by these human passions, drawing away their intelligence, while they describe the origin and production of the Word of God in the fifth place, they assert that thus they teach wonderful mysteries, unspeakable and sublime, known to no one but themselves.
It was, [they affirm,] concerning these that the Lord said, “Seek, and you shall find,” that is, that they should inquire how Nous and Aletheia proceeded from Bythus and Sage; whether Logos and Zoe again derive their origin from these and then, whether Anthropos and Ecclesia proceed from Logos and Zoe.
