8 This Being, therefore, also made spiritual things, of which, as far as to the third heaven, the apostle was made a spectator, and heard unspeakable words which it is not possible for a man to utter, inasmuch as they are spiritual; and He Himself bestows [gifts] on the worthy as inclination prompts Him, for paradise is His; and He is truly the Spirit of God, and not an animal Demiurge, otherwise He should never have created spiritual things. But if He really is of an animal nature, then let them inform us by whom spiritual things were made.
They have no proof which they can give that this was done by means of the travail of their Mother, which they declare themselves to be. For, not to speak of spiritual things, these men cannot create even a fly, or a gnat, or any other small and insignificant animal, without observing that law by which from the beginning animals have been and are naturally produced by God — through the deposition of seed in those that are of the same species. Nor was anything formed by the Mother alone; [for] they say that this Demiurge was produced by her, and that he was the Lord (the author) of all creation.
And they maintain that he who is the Creator and Lord of all that has been made is of an animal nature, while they assert that they themselves are spiritual,— they who are neither the authors nor lords of any one work, not only of those things which are extraneous to them, but not even of their own bodies! Moreover, these men, who call themselves spiritual, and superior to the Creator, do often suffer much bodily pain, sorely against their will.
