"Jesus Christ reigns here over the minds of his servants by faith, and over their hearts by charity. The greatest enemies of his spiritual kingdom are errors and vices, heresies, schisms, and scandals. Christ himself has foretold that his Church on Earth should have such enemies to encounter. She is not here below in the place of her repose, but in a place of trial, and in a foreign country. She must of course necessarily expect to meet with severe trials and persecutions, and must be prepared to combat them."
