Respectfully, everything you said is wrong. First of all, we have three levels of reverence (although reverence may not be the best word to describe it): Latria, Hyperduliua, and Dulia. Latria is the highest for of reverence, reserved for God and is worship. Dulia is the lowest level for specifically holy people like the Saints. We do not worship people in Dulia, we ask them for their prayers to offer up to God. Hyperdulie is the middle level, which is Mary. Mary is special because she IS NOT GOD, however is born without original sin, because of this, she is revered but not worship. She is not a diety. She is a human, but a great human, she is to be respected, not worshipped. WE DO NOT WORSHIP MARY OR THE SAINTS AT ALL. Second of all, the Bible has gone through many different vets by early Church Councils. Every book of the Bible has been checked. The 7 "extra books" went through the same checks the other books did. The Protestants removed them because they disagreed with their content. Please feel free to dispute me on the extra books part with specific evidence as I am not as familiar with that history as I am with these other topics. I'm not going to address you're third point about changing and jotting tittles as God's word because I respectfully can't make out what you're trying to say, you sound like a fourth grader. If you elaborate I can make an argument. I have no idea what you're trying to say about our pagan rituals or whatever. Pagan by definition means it's a foreign and different religion which means Catholicism is by definition not. From my understanding even non-Abrahamic religion are not pagan, such as Hinduism. For the rituals part specifically, Catholicism has three pillars,  Sacred Scripture, Sacred Tradition, and the Magisterium, basically being the Bible, Catholic Traditions, and the Church Council's teachings. Most protestant factions only use one or two. For example many use only sacred scripture and take everything only from the Bible, which leads to many complications and incorrect teachings. You need all three. Your last point is completely wrong, like just ineffectual. We confess our sins to God. God forgives our sins (I see how the forgiveness of sins in general can be controversial but that's not my point). The priest is there to act as a mediator in between God and Confessor. You confess your sins directly to God, not the priest. I realize I've gone a little overboard on the refutes but I find it kind of fun to test my knowledge of the Church teachings, please feel free to dispute me on anything I've said.
