Pope John XV
"Are any bold enough to maintain that the priests of the Lord all over the world are to take their law from monsters of guilt like these—men branded with ignominy, illiterate men, and ignorant alike of things human and divine? If, holy fathers, we are bound to weigh in the balance the lives, the morals, and the attainments of the humblest candidate for the priestly office, how much more ought we to look to the fitness of him who aspires to be the Lord and Master of all priests! Yet how would it fare with us, if it should happen that the man the most deficient in all these virtues, unworthy of the lowest place in the priesthood, should be chosen to fill the highest place of all? What would you say of such a one, when you see him sitting upon the throne glittering in purple and gold? Must he not be the "Antichrist, sitting in the temple of God and showing himself as God"?
