The RCC was in existence in Christs time you say!!! How preposterous. Some of their rituals, beliefs, and vestments go back much farther than that. Way back to the Babylonians in fact.

Um, Riiiiiiggggghhhhht. Ill leave you to that dillusion.
You have evidence to the contrary? When did the Catholic church form?
