Is Catholicism Biblical?

Are Catholic practices in line with the Bible?

I would like to begin by saying that I have the deepest respect for Catholics and Catholicism. Having been to Catholic mass as a youth, I genuinely appreciate the sincerity and reverence some of Catholics have for God. This article is by no means meant to bash or ridicule these people. I am merely trying to point out the contradictions between Catholicism and what the Bible actually says.
