Final answer:
The Episcopal jurisdiction of the Catholic Church in Rome, known as the Papacy, is based on the concept of the Petrine Succession, with Rome's symbolic power reinforcing papal authority over Western Christianity.
Step-by-step explanation:
The Episcopal jurisdiction of the Catholic Church in Rome, dating back to early Christian times, is known as the Papacy. This institution has its origins in the belief in the Petrine Succession.
Where the Roman archbishops (eventually known as Popes) claimed to inherit the spiritual keys to heaven from the Apostle Peter, who was vested with this authority by Christ himself.
Over time, the Pope's role evolved, influenced by the symbolic power of Rome and the city's connection to the apostolic tradition, leading to the establishment of the Pope as the leader of the Roman Catholic Church and the figurehead for Western Christianity.
By the time of the Great Schism in 1054, when the Christian Church split into western and eastern branches, the organizational structure of the Roman Catholic Church was well-established, with the Pope at the helm of a hierarchy including cardinals, archbishops, bishops, and priests.
The Catholic Church's influence grew, especially in Western Europe where Rome was seen as a holy city, and multi-faceted efforts were made to reinforce the Church's divine authority, heritage, and role in guiding the faithful.
