Even the matter of religious liberty, which has cost the world more tears, more blood and more agony, than any other interest, will be helped by his presence. I know of no church, however tolerant; of no priesthood, however enlightened, which could be safely trusted with the tremendous power which universal conformity would confer. We should welcome all men of every shade of religious opinion, as among the best means of checking the arrogance and intolerance which are the almost inevitable concomitants of general conformity. Religious liberty always flourishes best amid the clash of competition of rival religious creeds.
