6. If, however, they labour to maintain that, while all material things, such as the heaven, and the whole world which exists below it, were indeed formed by the Demiurge, yet all things of a more spiritual nature than these,—those, namely, which are above the heavens, such as Principalities, Powers, Angels, Archangels, Dominations, Virtues,—were produced by a spiritual process of birth (which they declare themselves to be), then, in the first place, we prove from the authoritative Scriptures that all the things which have been mentioned, visible and invisible, have been made by one God. For these men are not more to be depended on than the Scriptures; nor ought we to give up the declarations of the Lord, Moses, and the rest of the prophets, who have proclaimed the truth, and give credit to them, who do indeed utter nothing of a sensible nature, but rave about untenable opinions. And, in the next place, if those things which are above the heavens were really made through their instrumentality, then let them inform us what is the nature of things invisible, recount the number of the Angels, and the ranks of the Archangels, reveal the mysteries of the Thrones, and teach us the differences between the Dominations, Principalities, Powers, and Virtues. But they can say nothing respecting them; therefore these beings were not made by them. If, on the other hand, these were made by the Creator, as was really the case, and are of a spiritual and holy character, then it follows that He who produced spiritual beings is not Himself of an animal nature, and thus their fearful system of blasphemy is overthrown.
