A certain promoter of heresy, after a discussion which had been held between us, in the presence of many persons, and [of which] notes of it had been taken, procured the document from those who had written out the notes, and added or removed whatever he chose, and changed things as he thought right, and published it abroad as if it were my work, but pointed in triumphant scorn at the expressions which he had himself inserted. The brethren in Palestine, indignant at this, sent a man to me, at Athens, to obtain from me an authentic copy of the work. Up to that time, I had never even read it over again or revised it: it had been so completely neglected and thrown aside, that it could hardly be found. Nevertheless, I sent it, andGod is witness that I am speaking the truthwhen I met the man himself who had adulterated the work, and took him to task for having done so, he answered, as if he were giving me satisfaction: I did it, because I wished to improve that treatise, and to purge away its faults. What kind of a purging was this that he applied to my treatise? Such a purging as Marcion, or [as] Apelles his successor, after they added to the Gospels and to the writings of the Apostle; they subverted the true text of Scripture. And this man, similarly, first took away the true statements which I had made, and then inserted what was false, to furnish grounds for accusation against me.
But, though those who have dared to do this are impious and heretical men, yet those who give credence to such accusations against us shall not escape the judgment of God. There are others also (not [just] a few), who have done this through a wish to throw confusion into the churches. Recently, a certain heretic who had seen me at Ephesus and had refused to meet me, and had not opened his mouth in my presence, but for some reason or another had avoided doing so, afterwards composed a treatise according to his own fancy—partly mine, partly his own—and sent it to his disciples in various places; I know that it reached those who were in Rome, and I do not doubt that it also reached others. He was also behaving in the same reckless way at Antioch, before I came there; and the treatise which he brought with him, came into the hands of many of our friends. But when I arrived, I took him to task in the presence of many persons, and, when he persisted, with a complete absence of shame, in the impudent defense of his forgery, I demanded that the book should be brought in among us, so that my mode of speech might be recognized by the brethren who, of course, knew the points on which I am accustomed to insist, and the method of teaching which I employ. However, he did not dare to bring in the book, and his assertions were refuted by them all, and he himself was convicted of forgery, and thus the brethren were taught a lesson on not to give ear to such accusations.
