Origen

“ Is it at all agreeable to reason, that he who dared to do so much for the human race, in order that, as far as in him lay, all the Greeks and Barbarians, who were looking for divine condemnation, might depart from evil, and regulate their entire conduct in a manner pleasing to the Creator of the world, should not have had a miraculous birth, but one the vilest and most disgraceful of all? ”

“ And I will ask of them as Greeks, and particularly of Celsus, who either holds or not the sentiments of Plato, and at any rate quotes them, whether He who sends souls down into the bodies of men, degraded Him who was to dare such mighty acts, and to teach so many men, and to reform so many from the mass of wickedness in the world, to a birth more disgraceful than any other, and did not rather introduce Him into the world through a lawful marriage? ”

“ It was to be expected, indeed, that those who would not believe the miraculous birth of Jesus would invent some falsehood. And their not doing this in a credible manner, but (their) preserving the fact that it was not by Joseph that the Virgin conceived Jesus, rendered the falsehood very palpable to those who can understand and detect such inventions. ”
