Answer: (A)

The Great Schism is about a fundamental split in Christianity that led to two separate branches: the Western Roman Catholic Church and the Eastern Orthodox Church. It culminated in a formal separation in 1054, driven by disputes over who should lead the church (the pope’s authority), theological disagreements such as the addition of the filioque clause to the Creed, and deep cultural and political differences between Latin-speaking Western Europe and Greek-speaking Byzantium. The result was a lasting division that shaped religious life, law, and identity in Europe and the surrounding regions for centuries, with separate liturgies, governance, and traditions in each tradition. This separation also influenced broader historical currents, including later conflicts and the enduring distance between East and West.
