Eastern Orthodox Christianity
Eastern Orthodox Christianity is a branch of Christianity that follows the teachings and traditions of the early Christian church as established in the Eastern Roman Empire. It is characterized by its emphasis on the authority of the Bible, the importance of tradition, the veneration of saints, and the sacraments. Eastern Orthodox Christians believe in the Trinity, the divinity of Christ, and the resurrection of the dead. The church is organized into autocephalous churches, each headed by a patriarch or metropolitan, with the Ecumenical Patriarch of Constantinople considered the "first among equals." Eastern Orthodox worship is known for its rich liturgical tradition, including elaborate ceremonies, icons, and chant.
