Origen

“ Nay, according to the Greeks themselves, all men were not born of a man and woman. For if the world has been created, as many even of the Greeks are pleased to admit, then the first men must have been produced not from sexual intercourse, but from the earth, in which spermatic elements existed ”

“ But as a further answer to the Greeks, who do not believe in the birth of Jesus from a virgin, we have to say that the Creator has shown, by the generation of several kinds of animals, that what He has done in the instance of one animal, He could do, if it pleased Him, in that of others, and also of man himself. For it is ascertained that there is a certain female animal which has no intercourse with the male (as writers on animals say is the case with vultures) , and that this animal, without sexual intercourse, preserves the succession of race. ”

“ And yet these are veritable fables, which have led to the invention of such stories concerning a man whom they regarded as possessing greater wisdom and power than the multitude, and as having received the beginning of his corporeal substance from better and diviner elements than others, because they thought that this was appropriate to persons who were too great to be human beings. ”
