But if, besides these reprehensible discrepancies be between faith and life, acts and words, exterior conduct and interior feelings, however numerous they be, anyone overlooks the overwhelming sum of authentic virtues, of spirit of sacrifice, fraternal love, heroic efforts of sanctity, he gives evidence of deplorable blindness and injustice. If later he forgets to apply the standard of severity, by which he measures the Church he hates, to other organizations in which he happens to be interested, then his appeal to an offended sense of purity identifies him with those who, for seeing the mote in their brother's eye, according to the Savior's incisive words, cannot see the beam in their own. But however suspicious the intention of those who make it their task, nay their vile profession, to scrutinize what is human in the Church, and although the priestly powers conferred by God are independent of the priest's human value, it yet remains true that at no moment of history, no individual, in no organization can dispense himself from the duty of loyally examining his conscience, of mercilessly purifying himself, and energetically renewing himself in spirit and in action. (Papal Encyclical, Mit Brennender Sorge, 14 March 1937).
