8 Does any one wish to praise Origen? Let him praise him as I do. From his childhood he was a great man, and truly a martyr's son. At Alexandria he presided over the school of the church, succeeding a man of great learning the presbyter Clement. So greatly did he abhor sensuality that, out of a zeal for God but yet one not according to knowledge, he castrated himself with a knife. Covetousness he trampled under foot. He knew the scriptures by heart and laboured hard day and night to explain their meaning. He delivered in church more than a thousand sermons, and published innumerable commentaries which he called tomes. These I now pass over, for it is not my purpose to catalogue his writings. Which of us can read all that he has written? And who can fail to admire his enthusiasm for the scriptures? If some one in the spirit of Judas the Zealot brings up to me his mistakes, he shall have his answer in the words of Horace:
'Tis true that sometimes Homer sleeps, but then
He's not without excuse:
The fault is venial, for his work is long.
Let us not imitate the faults of one whose virtues we cannot equal. Other men have erred concerning the faith, both Greeks and Latins, but I must not mention their names lest I should be supposed to defend Origen not by his own merits but by the errors of others. This, you will say, is to accuse them and not to excuse him. You would be right, if I had declared him not to have erred, or if I had professed a belief that the apostle Paul or an angel from heaven ought to be listened to in a depravation of the faith. But as it is seeing I frankly admit him to be wrong, I may read him on the same terms as I read others, because if he is wrong so also are they. But you may say, If error is common to many, why do you assail him alone? I answer, because he alone is praised by you as an apostle. Take away your exaggerated love for him, and I am ready to take away the greatness of my dislike. While you gather other men's faulty statements out of their books merely to defend Origen in his error, you extol this latter to the sky and will not allow that he has erred at all. Whosoever you are who are thus preaching new doctrines, I beseech you, spare the ears of the Romans, spare the faith of a church which an apostle has praised. Why after four hundred years do you try to teach us Romans doctrines of which until now we have known nothing? Why do you publicly proclaim opinions which Peter and Paul refused to profess? Until now no such teaching has been heard of, and yet the world has become christian. For my part I will hold fast in my old age the faith wherein I was born again in my boyhood. They speak of us as claytowners, made out of dirt, brutish and carnal, because, say they, we refuse to receive the things of the spirit; but of course they themselves are citizens of Jerusalem and their mother is in heaven. I do not despise the flesh in which Christ was born and rose again, or scorn the mud which, baked into a clean vessel, reigns in heaven. And yet I wonder why they who detract from the flesh live after the flesh, and cherish and delicately nurture that which is their enemy. Perhaps indeed they wish to fulfil the words of scripture: “love your enemies and bless them that persecute you.” I love the flesh, but I love it only when it is chaste, when it is virginal, when it is mortified by fasting: I love not its works but itself, that flesh which knows that it must be judged, and therefore dies as a martyr for Christ, which is scourged and torn asunder and burned with fire.
