天主教, or Catholicism, is a major branch of Christianity that believes in the teachings of Jesus Christ and the authority of the Pope. It emphasizes the importance of the sacraments, such as baptism and communion, as means of grace. Catholics gather for worship in churches and participate in the Mass, which is a central part of their faith. The religion has a rich tradition of rituals, prayers, and community service, aiming to promote love, compassion, and moral living among its followers.
