“ For although I say that I have never either found or read this word in the sacred Scriptures, yet other reasonings, which I immediately subjoined, are in no wise discrepant from this view, because I brought forward as an illustration human offspring, which assuredly is of the same kind as the begetter; and I said that parents are absolutely distinguished from their children by the fact alone that they themselves are not their children, or that it would assuredly be a matter of necessity that there would neither be parents nor children. ”
