The Catholic Church traces its origins to Jesus Christ, who is regarded by its tradition as its founder, with key establishment events around 30-33 AD. Apostolic tradition holds that Jesus appointed Peter as the leader, based on passages like Matthew 16:18.

Official Tradition

Roman Catholics maintain the Church began at Pentecost in 33 AD , when the Holy Spirit descended on the Apostles in Jerusalem, marking the birth of the universal ("catholic") Christian community.

Jesus is seen as the divine founder, selecting Peter—"the rock"—to lead it, with Peter later establishing the Roman see around 42 AD.

This view emphasizes unbroken apostolic succession through bishops, especially the Pope as Peter's successor.

Historical Development

Early Christianity spread from Jerusalem to Antioch and Rome, facing persecution until Emperor Constantine's Edict of Milan in 313 AD legalized it.

The term "Catholic Church" first appears around 110 AD from Ignatius of Antioch, denoting the universal body of believers.

By the 4th-5th centuries, councils like Nicaea (325 AD) and imperial decrees solidified Rome's primacy, shaping the institutional Church.

Protestant Perspectives

Many Protestants view the true Church as starting at Pentecost but see Roman Catholicism evolving later through traditions diverging from Scripture.

Key markers include the East-West Schism of 1054 AD, after which "Catholic" specifically meant the Western (Roman) branch.

Others point to 4th-5th century developments under popes like Leo I (440-461 AD) as the "founding" of papal supremacy.
