Rufinus's Epilogue to Pamphilus the Martyr's Apology for Origen
Again, the other Clement, the presbyter of Alexandria, and the teacher of that church, in almost all his books describes the three Persons as having one and the same glory and eternity: and yet we sometimes find in his books passages in which he speaks of the Son as a creature of God. Is it credible that so great a man as he, so orthodox in all points, and so learned, either held opinions mutually contradictory, or left in writing views concerning God which it is an impiety, I will not say to believe, but even to listen to?
Once more, Dionysius the Bishop of Alexandria, was a most learned maintainer of the church's faith, and in passages without end defended the unity and eternity of the Trinity, so earnestly that some persons of less insight imagine that he held the views of Sabellius; yet in the books which he wrote against the heresy of Sabellius, there are things inserted of such a character that the Arians endeavour to shield themselves under his authority, and on this account the holy Bishop Athanasius felt himself compelled to write an apology for his work, because he was assured that he could not have held strange opinions or have written things in which he contradicted himself, but felt sure that these things had been interpreted by ill disposed men.
This opinion we have been led to form by the force of the facts themselves, in the case of these very reverend men and doctors of the church; we have found it impossible, I say, to believe that those reverend men who again and again have supported the church's belief should in particular points have held opinions contradictory to themselves. As to Origen, however, in whom, as I have said above, are to be found, as in those others, certain diversities of statement, it will not be sufficient to think precisely as we think or feel about those who enjoy an established reputation for orthodoxy; nor could a similar charge be met by a similar excuse, were it not that its validity is shown by words and writings of his own in which he makes this fact the subject of earnest complaint. What he had to suffer while still living in the flesh, while still having feeling and sight, from the corruption of his books and treatises, or from counterfeit versions of them, we may learn clearly from his own letter which he wrote to certain intimate friends at Alexandria; and by this you will see how it comes to pass that some things which are self-contradictory are found in his writings.
Some of those persons who take a pleasure in accusing their neighbours, bring against us and our teaching the charge of blasphemy, though from us they have never heard anything of the kind. Let them take heed to themselves how they refuse to mark that solemn injunction which says that 'Revilers shall not inherit the kingdom of God,' when they declare that I hold that the father of wickedness and perdition, and of those who are cast forth from the kingdom of God, that is the devil, is to be saved, a thing which no man can say even if he has taken leave of his senses and is manifestly insane. Yet it is no wonder, I think, if my teaching is falsified by my adversaries, and is corrupted and adulterated in the same manner as the epistle of Paul the Apostle. Certain men, as we know, compiled a false epistle under the name of Paul, so that they might trouble the Thessalonians as if the day of the Lord were near at hand, and thus beguile them. It is on account of that false epistle that he wrote these words in the second epistle to the Thessalonians: 'We beseech you, brethren, by the coming of our Lord Jesus Christ and our gathering together unto him; to the end that ye be not quickly shaken from your mind, nor yet be troubled, either by spirit or by word or by letter as sent from us, as that the day of the Lord is at hand. Let no man beguile you in any wise.' It is something of the same kind, I perceive, which is happening to us also. A certain promoter of heresy, after a discussion which had been held between us in the presence of many persons, and notes of it had been taken, procured the document from those who had written out the notes, and added or struck out whatever he chose, and changed things as he thought right, and published it abroad as if it were my work, but pointing 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: and,—God is witness that I am speaking the truth,—when 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 dissertation? Such a purging as Marcion or his successor Apelles after him gave 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 a few, who have done this through a wish to throw confusion into the churches. Lately, 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 other had avoided doing so, afterwards composed a dissertation 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 doubt not that it reached others also. He was behaving in the same reckless way at Antioch also before I came there: and the dissertation 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 defence of his forgery, I demanded that the book should be brought in amongst 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. He did not, however, venture 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 not to give ear to such accusations. If then any one is willing to trust me at all—I speak as in the sight of God—let him believe what I say about the things which are falsely inserted in my letter. But if any man refuses to believe me, and chooses to speak evil of me, it is not to me that he does the injury: he will himself be arraigned as a false witness before God, since he is either bearing false witness against his neighbour, or giving credit to those who bear it.
