Page "Christian denomination" Paragraph 2

Christians have various doctrines about the Church, the body of faithful that they believe was established by Jesus Christ, and how the divine church corresponds to Christian denominations.

Both the Catholics and the Eastern Orthodox consider each of themselves solely to faithfully represent the One Holy Catholic and Apostolic Church to the exclusion of the other.

Protestants separated from the Catholic Church because of theologies and practices that they considered to be in violation of their interpretation of fundamental Christian doctrine.

Generally, members of the various denominations acknowledge each other as Christians, at least to the extent that they have mutually-recognized baptisms and acknowledge historically orthodox views including the Divinity of Jesus and doctrines of sin and salvation, even though doctrinal and ecclesiological obstacles hinder full communion between churches.
