Origen

“ Could it have come to pass without divine assistance, that Jesus, desiring during these years to spread abroad His words and teaching, should have been so successful, that everywhere throughout the world, not a few persons, Greeks as well as Barbarians, learned as well as ignorant, adopted His doctrine, so that they struggled, even to death in its defence, rather than deny it, which no one is ever related to have done for any other system? ”

“ And if any one, on a candid consideration of these things, shall admit that no improvement ever takes place among men without divine help, how much more confidently shall he make the same assertion regarding Jesus, when he compares the former lives of many converts to His doctrine with their after conduct, and reflects in what acts of licentiousness and injustice and covetousness they formerly indulged, until, as Celsus, and they who think with him, allege, “they were deceived,” and accepted a doctrine which, as these individuals assert, is destructive of the life of men ”

“ Christianity, but from a desire thoroughly to examine the facts, would say that even those who are engaged in the healing of numbers of sick persons, do not attain their object—the cure of the body—without divine help ”
