In what year did the Eastern Orthodox Church split from the Roman Catholic Church?

• A. 1053
• B. 1054
• C. 451
• D. 313

Answer: (B)

The main idea is when the Eastern and Western branches of Christianity formally stopped sharing communion. This is commonly dated to 1054, the year the Pope’s legate and the Patriarch of Constantinople excommunicated each other, signaling a final break between the Roman Catholic and Eastern Orthodox churches. The split came after a long buildup of disagreements over authority (papal supremacy versus a collaborative patriarchate) and theology and practice, including issues like the Filioque clause. While the process had been unfolding for centuries, 1054 marks the event historians use to mark the division. By contrast, the other years reflect different moments: 451 is the Council of Chalcedon, which addressed Christology but didn’t cause the split; 313 is the Edict of Milan, which legalized Christianity in the Roman Empire; and 1053 isn’t tied to a defining rupture. So the year most associated with the split is 1054.
