What are the key differences between the 3 branches of Christianity?

The key differences between the three branches of Christianity - Catholicism, Protestantism, and Eastern Orthodoxy - lie in their beliefs, practices, and organizational structures. Catholicism recognizes the authority of the Pope and emphasizes sacraments and tradition. Protestantism emphasizes individual interpretation of the Bible and salvation through faith alone. Eastern Orthodoxy places importance on tradition, icons, and the authority of the Patriarch. These differences have led to distinct theological and cultural differences among the branches.
