bare their allegations; and he shall find them agreeable to the doctrine of the apostles, and so to maintain what they used to teach, and were persuaded of, that there is one God, the Maker of all things. And when he shall have divested his mind of such error, and of that blasphemy against God which it implies, he will of himself find reason to acknowledge that both the Mosaic law and the grace of the new covenant, as both fitted for the times [at which they were given], were bestowed by one and the same God for the benefit of the human race. 12. For all those who are of a perverse mind, having been set against the Mosaic legisla- tion, judging it to be dissimilar and contrary to the doctrine of the Gospel, have not applied themselves to investigate the causes of the difference of each covenant. Since, therefore, they have been deserted by the paternal love, and puffed up by Satan, being brought over to the doctrine of Simon Magus, they have apostatized in their opinions from Him who is God, and imagined that they have themselves discovered more than the apostles, by finding out another god; and [maintained] that the apostles preached the Gospel still somewhat under the influence of Jewish opinions, but that they themselves are purer [in doctrine], and more intelligent, than the apostles. Wherefore also Marcion and his followers have betaken 435 themselves to mutilating the Scriptures, not acknowledging some books at all; and, curtailing the Gospel according to Luke and the Epistles of Paul, they assert that these are alone au- thentic, which they have themselves thus shortened. In another work,866 however, I shall, God granting [me strength], refute them out of these which they still retain. But all the rest, inflated with the false name of “knowledge,” do certainly recognise the Scriptures; but they pervert the interpretations, as I have shown in the first book. And, indeed, the followers of Marcion do directly blaspheme the Creator, alleging him to be the creator of evils, [but] holding a more tolerable867 theory as to his origin, [and] maintaining that there are two beings, gods by nature, differing from each other,—the one being good, but the other evil. Those from Valentinus, however, while they employ names of a more honourable kind, and set forth that He who is Creator is both Father, and Lord, and God, do [nevertheless] render their theory or sect more blasphemous, by maintaining that He was not produced from any one of those Æons within the Pleroma, but from that defect which had been expelled beyond the Pleroma. Ignorance of the Scriptures and of the dispensation of God has brought all these things upon them. And in the course of this work I shall touch upon the cause of the difference of the covenants on the one hand, and, on the other hand, of their unity and harmony. 866 No reference is made to this promised work in the writings of his successors. Probably it never was un- dertaken. 867 Most of the mss. read “intolerabiliorem,” but one reads as above, and is followed by all the editors. 1101 Chapter XII.—Doctrine of the rest of the apostles.
