Eastern Christian Traditions refer to the diverse practices and beliefs of Christianity that developed in Eastern Europe, the Middle East, and parts of Asia. This includes the Eastern Orthodox Church, which emphasizes the importance of tradition, liturgy, and the sacraments. Key figures in this tradition include the Church Fathers, who shaped theological understanding and practices. Another significant aspect is the Oriental Orthodox Churches, which separated from the Eastern Orthodox Church after the Council of Chalcedon in 451 AD. These churches, such as the Coptic Orthodox Church and the Armenian Apostolic Church, maintain unique theological perspectives and liturgical practices, reflecting their rich historical and cultural heritage.
