Orthodox churches are Christian communities that follow the traditions and teachings of the Eastern Orthodox Church and the Oriental Orthodox Church. They emphasize the importance of the sacraments, particularly the Eucharist, and maintain a rich liturgical life. The churches are known for their beautiful icons and elaborate rituals, which reflect their deep spiritual heritage. The Orthodox Church is organized into various national and regional branches, such as the Greek Orthodox Church and the Russian Orthodox Church. Each branch has its own hierarchy and practices, but they all share core beliefs and a commitment to preserving the teachings of the early Christian church.
