Catholic Church
The Catholic Church, also known as the Roman Catholic Church, is the largest Christian church, with more than 1.25 billion members worldwide. One of the oldest religious institutions in the world, it has played a prominent role in the history of Western civilisation.Headed by the Bishop of Rome, known as the Pope, its doctrines are summarised in the Nicene Creed. The Catholic Church is also notable within the Western Christian tradition for its celebration of the seven sacraments.
The Catholic Church teaches that it is the one true church founded by Jesus Christ, that its bishops are the successors of Christ's apostles, and that the Pope is the successor to Saint Peter. The Church maintains that the doctrine on faith and morals that it declares as definitive is infallible. The Latin Church, the autonomous Eastern Catholic Churches and religious institutes such as the Jesuits, mendicant orders and enclosed monastic orders, reflect a variety of theological emphases in the Church.
