25. The sixth book reveals the full deceitfulness of this heretical teaching. To win credit for their assertions they denounce the impious doctrine of heretics:—of Valentinus, to wit, and Sabellius and Manichæus and Hieracas, and appropriate the godly language of the Church as a cover for their blasphemy. They reprove and alter the language of these heretics, correcting it into a vague resemblance to orthodoxy, in order to suppress the holy faith while apparently denouncing heresy. But we state clearly what is the language and what the doctrine of each of these men, and acquit the Church of any complicity or fellowship with condemned heretics. Their words which deserve condemnation we condemn, and those which claim our humble acceptance we accept. Thus that Divine Sonship of Jesus Christ, which is the object of their most strenuous denial, we prove by the witness of the Father, by Christ’s own assertion, by the preaching of Apostles, by the faith of believers, by the cries of devils, by the contradiction of Jews, in itself a confession, by the recognition of the heathen who had not known God; and all this to rescue from dispute a truth of which Christ had left us no excuse for ignorance.
