So why pretend you have reasoned your way out of the faith? In fact, of all religions, Catholicism is most reasonable.
Sez you. I found that having three G-ds is kinda polytheistic (yeah yeah yeah, I've heard the old three-in-one thing before, and I didn't buy it then, either).
Furthermore, you literally pray to people (saints, Mary, etc). It's like you are worshiping them, too, especially Mary.
