Orthodox Christianity is one of the oldest branches of Christianity, with roots tracing back to the early Christian communities. It is characterized by its adherence to the traditions and teachings of the Apostles and the early Church Fathers. The Orthodox Church emphasizes the importance of the sacraments, particularly the Eucharist, and maintains a rich liturgical life. The Orthodox Christian faith is organized into various national churches, such as the Greek Orthodox Church and the Russian Orthodox Church. These churches share core beliefs but may have different cultural practices and languages. The Orthodox community celebrates its faith through vibrant rituals, icons, and a strong sense of community.
