"IT IS the peculiar property of the Church that when she is buffeted she is triumphant, when she is assaulted with argument she proves herself in the right, when she is deserted by her supporters she holds the field. It is her wish that all men should remain at her side and in her bosom; if it lay with her, none would become unworthy to abide under the shelter of that august mother, none would be cast out or suffered to depart from her calm retreat. But when heretics desert her or she expels them, the loss she endures, in that she cannot save them, is compensated by an increased assurance that she alone can offer bliss."
~St. Hilary of Poitiers (4th cent.): On the Trinity, 7, 4.
