What is a good religion to compare and contrast Catholicism with?

I am writing a Report on Catholicism. Part of the report is to compare and contrast my religion of choice with another religion.What I want to know is what religion is going to effectively compare and contrast with Catholicism? Any ideas are welcome!(Thanks!) ------

Protestants. The Protestants were originally Roman Catholice, but in the 1500's, Martin Luther, a Catholic monk, led a sort of revolt against the Catholic Church, and nailed 95 theses in the door of the Catholic Church in Wittenburg, Germany. These were to protest the wickednesses in the Catholic Church. Those who followed him came to be called Lutherans. Martin Luther's break from the Catholic Church was not his idea, it was the church who excommunicated him. His'reformation'changed the entire world, as his teachings spread like wildfire. Prior to the Reformation, the world was in the'dark ages'. People could not read or write. Martin translated the Bible into German, and he opened schools to teach people to read and write. The world came out of the dark ages. This would be a very interesting topic for you. If you Google'Reformation'you will find much interesting, additional information. Best wishes. ------
