Catholicism is a broad term for the body of the Catholic faith, its theologies and doctrines, its liturgical, ethical, spiritual, and behavioral characteristics, as well as a religious people as a whole.

The Catholic Church, also known as the Roman Catholic Church, is the largest Christian church, with approximately 1.3 billion baptised Catholics worldwide as of 2017. As the world’s oldest continuously functioning international institution, it has played a prominent role in the history and development of Western civilisation. The church is headed by the Bishop of Rome, known as the pope. Its central administration, the Holy See, is in the Vatican City, an enclave within the city of Rome in Italy.

Catholic theology is based on the Nicene Creed. The Catholic Church teaches that it is the One, Holy, Catholic and Apostolic church founded by Jesus Christ in his Great Commission, that its bishops are the successors of Christ’s apostles, and that the pope is the successor to Saint Peter upon whom primacy was conferred by Jesus Christ.
