Cause of the Schism: The Struggle for Papal Authority
A primary cause of the Great Schism of 1054 was a fierce power struggle over church leadership: the Western Pope claimed supreme authority over all Christians, while the Eastern Patriarch of Constantinople shared power with other bishops and the Byzantine emperor, as covered in Pengi Social Studies Grade 7, Chapter 1: The Byzantine Empire. When the Pope demanded submission and Eastern bishops refused, mutual excommunication sealed the split between the Roman Catholic and Eastern Orthodox churches.
Key Concepts
A primary cause of the split was a fierce power struggle over church leadership. In the West, the Pope claimed supreme authority over all Christians, arguing that as the successor to Saint Peter, he held power over kings and other bishops. In contrast, the East was led by the Patriarch of Constantinople, who shared authority with other bishops and recognized the Byzantine emperor as the guardian of the faith.
The Eastern bishops rejected the Pope's claim to absolute power. They believed in a council based leadership structure rather than a single monarchy within the church. When the Pope sent representatives to Constantinople to demand submission, it resulted in mutual excommunication , sealing the break between the two churches.
