A few questions for those who think Catholicism isn't Christian?

Yes I know many Catholics. You might enjoy reading "Falling Away" by B H Roberts, or "The Great Apostasy" by James E. Talmage. The early Christian religion was very simple with few rites, like faith, repentance and baptism. The Catholic church has a lot of fancy rituals, don't baptize by immersion and so on. The Church of Jesus Christ was not meant to be wealthy and pompous.
