The Eastern Catholic Church refers to a group of 23 particular churches that are in full communion with the Roman Catholic Church. These churches follow various Eastern Christian traditions, including liturgical practices, theology, and spirituality, while recognizing the authority of the Pope in Rome. They maintain their unique identities and customs, which are rooted in the early Christian communities of the East. Each Eastern Catholic Church has its own hierarchy and governance, often led by a patriarch or major archbishop. Examples include the Melkite Greek Catholic Church and the Syro-Malabar Catholic Church. Together, they contribute to the rich diversity of the global Catholic Church while preserving their distinct cultural heritages.
