Tertullian

“ Consider, again, those extraordinary conceptions, which were more wonderful still, of the barren woman and the virgin: these women would only be able to produce imperfect offspring against the course of nature, from the very fact that one of them was too old to bear seed, and the other was pure from the contact of man. If there was to be bearing at all in the case, it was only fitting that they should be born without a soul, (as the philosopher would say,) who had been irregularly conceived. However, even these have life, each of them in his mother’s womb. ”

“ Now there is no end to the uncertainty and irregularity of human opinion, until we come to the limits which God has prescribed. I shall at last retire within our own lines and firmly hold my ground there, for the purpose of proving to the Christian (the soundness of) my answers to the Philosophers and the Physicians. ”
