Quick Summary

Roman Catholicism traces its origins to Jesus Christ and his disciples in the 1st century CE. Tradition holds that Jesus appointed his apostle Peter as the leader of the church, and Peter is considered the first bishop of Rome and the first pope. The church developed a sophisticated theology and organizational structure, influenced by historical and cultural factors.12

Key elements of Catholic Christianity, such as doctrine, authority, and universality, are evident in the New Testament. Over centuries, the church established its authority through Scriptures, apostolic succession, and tradition. The Council of Trent (1545-1563) was a pivotal event, solidifying Catholic doctrine in response to the Protestant Reformation and reforming the church's internal life and discipline. Popes like Leo I and Gregory I played significant roles in shaping the early medieval papacy and extending Roman Catholicism's influence. Core beliefs include the Holy Trinity, the Incarnation, Passion, and Resurrection of Christ, and the importance of sacraments.3456
