The Orthodox Faith refers to the branch of Christianity that follows the traditions and teachings of the early Church. It is characterized by its adherence to the seven ecumenical councils and the importance of the sacraments, particularly the Eucharist. The Orthodox Church emphasizes the continuity of faith and practice from the time of the apostles. The Eastern Orthodox Church is the largest group within the Orthodox Faith, comprising various national churches, such as the Greek Orthodox and Russian Orthodox churches. Worship in the Orthodox tradition often includes rich liturgical practices, icons, and a strong sense of community, reflecting its historical roots and theological beliefs.
