Roman Catholic
The Roman Catholic Church is the largest Christian denomination in the world, with approximately 1.3 billion baptized members. It understands itself as the one Church founded by Jesus Christ on the Apostle Peter, whose episcopal succession continues in the Bishop of Rome (the Pope). Governance is hierarchical, with the Pope holding supreme authority in matters of faith and morals, exercised in communion with the college of bishops. Catholic doctrine is comprehensively articulated in the Catechism of the Catholic Church (1992) and is shaped by Scripture, Sacred Tradition, and the Magisterium—the Church's teaching authority.
