Translated from the Greek original by Frederick Crombie.
2. It was, indeed, matter of surprise to men even of ordinary intelligence, that one who was accused and assailed by false testimony, but who was able to defend Himself, and to show that He was guilty of none of the charges (alleged), and who might have enumerated the praiseworthy deeds of His own life, and His miracles wrought by divine power, so as to give the judge an opportunity of delivering a more honourable judgment regarding Him, should not have done this, but should have disdained such a procedure, and in the nobleness of His nature have contemned His accusers.  That the judge would, without any hesitation, have set Him at liberty if He had offered a defence, is clear from what is related of him when he said, "Which of the two do ye wish that I should release unto you, Barabbas or Jesus, who is called Christ?"  and from what the Scripture adds, "For he knew that for envy they had delivered Him."  Jesus, however, is at all times assailed by false witnesses, and, while wickedness remains in the world, is ever exposed to accusation. And yet even now He continues silent before these things, and makes no audible answer, but places His defence in the lives of His genuine disciples, which are a pre-eminent testimony, and one that rises superior to all false witness, and refutes and overthrows all unfounded accusations and charges.
3. I venture, then, to say that this "apology" which you require me to compose will somewhat weaken that defence (of Christianity) which rests on facts, and that power of Jesus which is manifest to those who are not altogether devoid of perception. Notwithstanding, that we may not have the appearance of being reluctant to undertake the task which you have enjoined, we have endeavoured, to the best of our ability, to suggest, by way of answer to each of the statements advanced by Celsus, what seemed to us adapted to refute them, although his arguments have no power to shake the faith of any (true) believer. And forbid, indeed, that any one should be found who, after having been a partaker in such a love of God as was (displayed) in Christ Jesus, could be shaken in his purpose by the arguments of Celsus, or of any such as he. For Paul, when enumerating the innumerable causes which generally separate men from the love of Christ and from the love of God in Christ Jesus (to all of which, the love that was in himself rose superior), did not set down argument among the grounds of separation. For observe that he says, firstly: "Who shall separate us from the love of Christ? Shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword? (as it is written, For Thy sake we are killed all the day long; we are accounted as sheep for the slaughter.) Nay, in all these things we are more than conquerors through Him that loved us."  And secondly, when laying down another series of causes which naturally tend to separate those who are not firmly grounded in their religion, he says: "For I am persuaded that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord."
