Around 1000 C.E. How did beliefs about church authority differ between west church leaders and eastern church leaders

Answer 1

Around 1000 C.E., differences in beliefs about church authority between Western church leaders (headed by the Pope) and Eastern church leaders (headed by the Patriarch of Constantinople) were a major factor contributing to the Great Schism of 1054.

West Church Leaders:
- Rome (the Pope) was considered the center of authority in the Western Church.
- The Pope claimed to have universal jurisdiction over the Church, meaning he had authority over all Christian churches and bishops.
- The Pope also claimed the ability to excommunicate other church leaders, including those in the East.
- The Latin language was used in liturgy and religious texts in the Western Church, and Latin was the primary language for church proceedings and theological discussions.
- The Western Church emphasized the importance of the Bishop of Rome as the successor of Saint Peter, and held that the Pope was the supreme authority in matters of doctrine and church governance.

Eastern Church Leaders:
- Constantinople (the Patriarch), as the political and religious capital of the Byzantine Empire, was considered the center of authority in the Eastern Church.
- Eastern church leaders believed in a shared source of authority between five major patriarchates (Rome, Constantinople, Alexandria, Antioch, and Jerusalem), where each patriarch had equal authority within their own jurisdiction.
- The Eastern Church rejected the idea of the Pope's universal jurisdiction and considered the Pope to be the "first among equals" (primus inter pares) among patriarchs.
- Greek was the primary language used in liturgy and religious texts in the Eastern Church, and Greek was the language for theological discussions and church proceedings.
- The Eastern Church placed a strong emphasis on the conciliar nature of church decision-making, where decisions were made collectively through councils (such as the ecumenical councils) involving bishops from various regions.

These differing beliefs in church authority, along with other theological, cultural, and political factors, eventually led to the Great Schism of 1054, when formal separation occurred between the Roman Catholic Church (West) and the Eastern Orthodox Church (East).
