Context: Among the “some two hundred and fifty-eight” Vicars of Christ there were probably some good men. This would have happened even if the intention had been to get all bad men, for the reason that man reaches perfection neither in good nor in evil; but if they were selected by Christ himself, if they were selected by a church with a divine origin and under divine guidance, then there is no way to account for the selection of a bad one. If one hypocrite was duly elected pope—one murderer, one strangler, one starver—this demonstrates that all the popes were selected by men, and by men only, and that the claim of divine guidance is born of zeal and uttered without knowledge.
