"Katholiken" refers to members of the Roman Catholic Church, one of the largest Christian denominations in the world. They follow the teachings of Jesus Christ and the authority of the Pope, who is based in Vatican City. The Catholic faith emphasizes the importance of the sacraments, such as baptism and communion, as essential for spiritual life. The beliefs of Katholiken are rooted in the Bible and the traditions of the Church. They celebrate various religious events, including Christmas and Easter, which commemorate significant moments in the life of Jesus. The Catholic Church also engages in charitable work and promotes social justice as part of its mission.
