Eastern Orthodox Church

The Eastern Orthodox Church emerged as a dominant religious institution within the Byzantine Empire after Christianity became the state religion in the 4th century. It upheld traditional beliefs and practices, emphasizing the importance of the Church’s teachings and sacraments. The church was closely linked to the Byzantine state, with the Emperor often seen as the protector of the faith. Its organization included a hierarchy of bishops led by the Ecumenical Patriarch. Differences in theology and practice eventually led to a split with the Roman Catholic Church in 1054, marking a pivotal moment in Christian history.
