Christianity is the Catholic Church

"There is not...and never will be any reconciliation between Christianity and the experimental method. Christianity is the great church and nothing else is Christianity. To call anything else Christianity is to plunge into confusion and chaos; and it is an insult to Christianity. Christianity is a great thing, not a little one; one thing not many things; a rich thing not a poor thing; a majestic thing not a thing of shreds and patches. Christianity is Christianity at its noblest, truest, and most comprehensive, and that is the Catholic church. If you desire to be a Christian, join it. It will make no demands upon you that are more fearful than the demands made upon you by any peddling form of Christianity. It asks no greater sacrifice than Little Bethel or the Church of England; and it does not insult your intelligence by inviting you to become a member of a contradiction in terms."
