Those, then, who are of the school of Valentinus being overthrown, the whole multitude of heretics are, in fact, also subverted. For all the arguments I have advanced against their Pleroma, and with respect to those things which are beyond it, showing how the Father of all is shut up and circumscribed by that which is beyond Him (if, indeed, there be anything beyond Him), and how there is an absolute necessity [on their theory] to conceive of many Fathers, and many Pleromas, and many creations of worlds, beginning with one set and ending with another, as existing on every side; and that all [the beings referred to] continue in their own domains, and do not curiously intermeddle with others, since, indeed, no common interest nor any fellowship exists between them; and that there is no other God of all, but that that name belongs only to the Almighty;--[all these arguments, I say,] will in like manner apply against those who are of the school of Marcion, and Simon, and Meander, or whatever others there may be who, like them, cut off that creation with which we are connected from the Father. The arguments, again, which I have employed against those who maintain that the Father of all no doubt contains all things, but that the creation to which we belong was not formed by Him, but by a certain other power, or by angels having no knowledge of the Propator, who is surrounded as a centre by the immense extent of the universe, just as a stain is by the [surrounding] cloak; when I showed that it is not a probable supposition that any other being than the Father of all formed that creation to which we belong,-- these same arguments will apply against the followers of Saturninus, Basilides, Carpocrates, and the rest of the Gnostics, who express similar opinions. Those statements, again, which have been made with respect to the emanations, and the Aeons, and the [supposed state of] degeneracy, and the inconstant character of their Mother, equally overthrow Basilides, and all who are falsely styled Gnostics, who do, in fact, just repeat the same views under different names, but do, to a greater extent than the former, ¹ transfer those things which lie outside ² of the truth to the system of their own doctrine. And the remarks I have made respecting numbers will also apply against all those who misappropriate things belonging to the truth for the support of a system of this kind. And all that has been said respecting the Creator (Demiurge) to show that he alone is God and Father of all, and whatever remarks may yet be made in the following books, I apply against the heretics at large. The more moderate and reasonable among them thou wilt convert and convince, so as to lead them no longer to blaspheme their Creator, and Maker, and Sustainer, and Lord, nor to ascribe His origin to defect and ignorance; but the fierce, and terrible, and irrational [among them] thou wilt drive far from thee, that you may no longer have to endure their idle loquaciousness.
