He who has compared human things with divine will require no further arguments on these points. And yet the latter opinion ought to be discussed, that God conferred divine honors in consideration of meritorious claims. Well, then, if the award was made on such grounds, if heaven was opened to men of the primitive age because of their deserts, we must reflect that after that time no one was worthy of such honor; except it be, that there is now no longer such a place for any one to attain to. Let us grant that anciently men may have deserved heaven by reason of their great merits. Then let us consider whether there really was such merit. Let the man who alleges that it did exist declare his own view of merit. Since the actions of men done in the very infancy of time are a valid claim for their deification, you consistently admitted to the honor the brother and sister who were stained with the sin of incest—Ops and Saturn.
