By "3 branches" I am assuming that you mean the three branches of the US government. The branches are the legislative, judicial, and executive branch. The legislative branch makes the laws, the judicial branch makes sure that the laws are constitutional and is also the Supreme Court, and the exectutive branch is the President, the Vice President, and the cabinet members.
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.
