Geography influenced the language, politics, and power centers of both the Eastern and Western Church.
The geographic locations of the Roman Catholic Church in Western Europe and the Eastern Orthodox Church in Eastern Europe and the Near East shaped their cultural development, including the languages used in religious services—Latin in the West and Greek in the East. Additionally, the differing political relationships—papal supremacy in the West and caesaropapism in the East—reflect how geographic boundaries impacted the authority and governance of the respective churches. Ultimately, geographic factors played a crucial role in creating distinct religious identities and ecclesiastical structures that contributed to the East-West Schism.
