All three of these religions are very similar, for they are all sects of Christianity and are born from each other, but here are some differences. || In Roman Catholic, the clergy all have to be male and unmarried. In Eastern Orthodox, the priests still have to be male but can marry before they become priests. Bishops still cannot marry. In Protestantism, the priests and bishops can marry and women are allowed to be priests. || Another difference is the position of power. In Roman Catholic, the priest is the leader of everyone. He is the one person who has the most power. In Eastern Orthodox, there is a group of people who have the highest position. Protestantism has no hierarchy. The people of the religion have the power to pick their leader like a democracy. || One more difference is how the religions treat the sacraments. The Roman Catholic and Eastern Orthodox faiths, they conduct all the sacraments (with some distinctions) and believe it will bring them salvation. In Protestantism, they believe that the sacraments are merely for God's grace, so they are not performed with the same kind of attitude. Protestants believe that it is all symbolic, while the other religions believe in the sacrifice and truth of the sacraments.
