As to our translations of the Περὶ ᾿Αρχῶν , yours was doing harm, and mine was necessary in self-defence. You should be glad that heresyis exposed.
34 “But why,” you ask, “did you accept my manuscripts which had been falsified? And why, when I had translated the Περὶ ᾿Αρχῶν did you dare to put your pen to the same work? If I had erred, as any man may, ought you not to summon me to reply by a private letter, and to speak smoothly to me, as I am speaking smoothly in my present letter?” My whole fault is this that, when accusations were brought against me in the guise of disingenuous praise, I tried to purge myself from them, and this without invidiously introducing your name. I wished to refer to many persons a charge which you alone had brought, not so as to retort the charge of heresy upon you, but to repel it from myself. Could I know that you would be angry if I wrote against the heretics? You had said that you had taken away the heretical passages from the works of Origen. I therefore turned my attacks not upon you but upon the heretics, for I did not believe that you were a favourer of heresy. Pardon me, if I did this with too great vehemence. I thought that I should give you pleasure. You say that it was by the dishonest tricks of those who acted for me that your manuscripts were brought out before the public, when they were kept secretly in your chamber, or were in possession only of the man who had desired to have the translation made for him. But how is this reconcilable with your former statement that either no one or very few had them? If they were kept secret in your chamber, how could they be in the possession of the man who had desired to have the translation made for him? If the one man for whom the manuscripts had been written had obtained them in order to conceal them, then they were not kept secret in your chamber, and they were not in the hands of those few who, as you now declare, possessed them. You accuse us of having stolen them away; and then again you reproach us with having bought them for a great sum of money and an immense bribe. In a single matter, and in one little letter, what a tissue of various and discordant falsehoods! You have full liberty for accusation, but I have none for defence. When you bring a charge, you think nothing about friendship. When I begin to reply, then your mind is full of the rights of friendship. Let me ask you: Did you write these manuscripts for concealment or for publication? If for concealment, why were they written? If for publication, why did you conceal them?
35. But my fault, you will say, was this, that I did not restrain your accusers who were my friends. Why, I had enough to do to answer their accusations against myself; for they charged me with hypocrisy, as I could show by producing their letters, because I kept silence when I knew you to be a heretic; and because by incautiously maintaining peace with you, I fostered the intestine wars of the Church. You call them my disciples; they suspect me of being your fellow disciple; and, because I was somewhat sparing in my rejection of your praises, they think me to be initiated, along with you, into the mysteries of heresy. This was the service your Prologue did me; you injured me more by appearing as my friend than you would had you shown yourself my enemy. They had persuaded themselves once for all (whether rightly or wrongly is their business) that you were a heretic. If I should determine to defend you, I should only succeed in getting myself accused by them along with you. They cast in my teeth your laudation of me, which they suppose to have been written not in craft but sincerity; and they vehemently reproach me with the very things which you always praised in me. What am I to do? To turn my disciples into my accusers for your sake? To receive on my own head the weapons which were hurled against my friend?
36. In the matter of the books Περὶ ᾿Αρχῶν, I have even a claim upon your gratitude. You say that you cut off anything that was offensive and replaced it by what was better. I have represented things just as they stood in the Greek. By this means both things are made to appear, your faith and the heresy of him whom you translated. The leading Christians of Rome wrote to me: Answer your accuser; if you keep silence, you will be held to have assented to his charges. All of them unanimously demanded that I should bring to light the subtle errors of Origen, and make known the poison of the heretics to the ears of the Romans to put them on their guard. How can this be an injury to you? Have you a monopoly of the translation of these books? Are there no others who take part in this work? When you translated parts of the Septuagint, did you mean to prohibit all others from translating it after your version had been published? Why, I also have translated many books from the Greek. You have full power to make a second translation of them at your pleasure; for both the good and the bad in them must be laid to the charge of their author. And this would hold in your case also, had you not said that you had cut out the heretical parts and translated only what was positively good. This is a difficulty which you have made for yourself, and which cannot be solved, except by confessing that you have erred as all men err, and condemning your former opinion.
