"In the worst days of Roman Catholicism, when the multitude professing that religion was steeped in ignorance and its worship was no better than idolatry, there was still a considerable portion of its priesthood fully acquainted with the text-book of Christianity. It was no doubt, with its priests a question of policy whether their flock should be admitted to the knowledge which they possessed, and restored to a purer faith; but that they had the power to work that change is borne out by the history of Protestantism."
