A question for Catholics...?

I am a Christian and through my relationship and walk with Christ over the years I have learned many things about the bible and God and other faiths/religions. And something has always been on my mind especially since my grandmother is catholic and people and friends I know are catholic..."why haven't Catholics figured out by now that Catholicism and most of its practices totally contradict what the bible says (even their own version!) and that technically it can accurately be labeled the biggest cult in the world." Its so obvious too! If any of you actually read the bible in addition to going to m you would realize that the idea of the pope, praying to Mary and the saints, and your way of baptizing is totally against what the bible says! Read it! It says all men have sinned and fallen short of the glory of God. That includes Mary! The only person that was without sin was Jesus! It also says that There is only one mediator between God and earth and that is Christ! Not Mary and not the pope who is just a man and nothing more! There is also a verse that says that you should not call anyone "father" on earth for there is only one father in heaven. And another is that you should not trust man and his teachings and traditions and that you should just trust God. All Catholicism is is traditions made by man. And a final fact is that the bible says that you should not repetitiously pray and mumble on like the heathens do. There are so many more contradictions but I think that's enough to realize something is wrong with Catholicism. So again my question is: Why do Catholics not see this as a problem when the bible clearly states it!?" Also I realize that Catholics put tradition and mans teachings above the bible...but you should realize that the bible is "God breathed" as it says and not "man breathed" as Catholicism is. It just makes me so confused, angry, and sad when people think they are doing what God wants and think they are saved but really they have become blind to the truth..which is the word of God.
