To the op: I'm catholic and I'll answer your questions with questions of my own. Why do you care about another religion other then your own? Are the explanations of your own religion not enough to explain Catholicism for you? If you wish to learn about different religions (Catholicism for that matter) all you need to do is take a college intro class on religions studies.
Who knows, you may get lucky like me and have an atheist teach it; boy did I enjoy that class. (Don't misunderstand, I meant to say the teacher was awesome)
