The Great Schism Documentary (1054): How Christianity Split into the Catholic and Orthodox Churches

For the first thousand years of its history, Christianity was one Church. From the ancient cities of Jerusalem, Antioch, Alexandria, Constantinople, and Rome, a shared faith spread across the Roman Empire and beyond. But beneath that unity, political rivalries, cultural differences, theological debates, and competing visions of authority were slowly driving East and West apart. In 1054, those centuries of tension reached a dramatic climax inside the Hagia Sophia in Constantinople, when a papal legate placed a bull of excommunication upon the altar. Although neither side realized it at the time, this moment would come to symbolize one of the most significant events in Christian history: The Great Schism. In this documentary, we explore the complete story of the division between the Roman Catholic Church and the Eastern Orthodox Church.
