Catholicism evolved from early Christianity through a process of theological development and institutional growth. In the early centuries of Christianity, there were many different interpretations of scripture and theological ideas. Over time, certain ideas and practices gained wider acceptance, leading to the formation of the Catholic Church. The Church became more organized and hierarchical, with the Pope as its spiritual leader. The Church also developed sacraments, such as baptism and communion, and created a system of canon law to govern its members.
