which title is used for the leader of the roman catholic church
Catholic Church The Catholic Church, also known as the Roman Catholic Church, is the largest Christian church, with more than 1.299Â billion members worldwide.[4] As one of the oldest religious institutions in the world, it has played a prominent role in the history and development of Western civilisation.[5] The church is headed by the Bishop of Rome, who is known as the Pope. The church's doctrines are summarised in the Nicene Creed. Its central administration, the Holy See, is in the Vatican City, an enclave within Rome, Italy.
Saint Peter Saint Peter (Syriac/Aramaic: ܫܸܡܥܘܿܢ ܟܹ݁ܐܦ݂ܵܐ, Shemayon Keppa; Hebrew: שמעון בר יונה‎ Shim'on bar Yona; Greek: Πέτρος Petros; Coptic: ⲡⲉⲧⲣⲟⲥ, translit. Petros; Latin: Petrus; r. AD 30;[1] died between AD 64 and 68),[2] also known as Simon Peter, Simeon, or Simon (/ˈsaɪmən/,  pronunciation (help·info)), according to the New Testament, was one of the Twelve Apostles of Jesus Christ, leaders of the early Christian Great Church. Pope Gregory I called him repeatedly the "Prince of the Apostles".[3] According to Catholic teaching, Jesus promised Peter in the "Rock of My Church" dialogue in Matthew 16:18 a special position in the Church. He is traditionally counted as the first Bishop of Rome‍—‌or pope‍—‌and also by Eastern Christian tradition as the first Patriarch of Antioch. The ancient Christian churches all venerate Peter as a major saint and as the founder of the Church of Antioch and the Roman Church,[2] but differ in their attitudes regarding the authority of his present-day successors (the primacy of the Bishop of Rome).
