Refers to the branch of Christianity characterized by a uniform, highly developed ritual canon and organizational structure with doctrinal roots based in the teachings of the Apostles of Jesus Christ in the first century, in the Alexandrian school of theology, and in Augustinian thought. In this religious branch, faith is considered an acceptance of revelation; revelation appears as doctrine. In juridical terms, it refers to the branch of Christianity distinguished as a unified, monolithic sacramental system under the governance of papal authority. Throughout much of its history, the seat of the Pope has been in Rome, thus "Roman Catholicism" is often used to distinguish this concept from the Orthodox Catholic church.
