Greek Orthodox vs. Roman Catholics: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on March 1, 2024
Greek Orthodox is Eastern Christian, with autocephalous churches; Roman Catholics are Western Christian, under the Pope's authority.
Key Differences
Greek Orthodox churches are led by a group of autocephalous patriarchs and bishops, emphasizing collective decision-making. In contrast, Roman Catholics recognize the Pope as the supreme religious authority, centralizing leadership in the Vatican.
Greek Orthodox liturgy is traditionally in ancient Greek and involves a highly ceremonial service, with significant emphasis on icons. Roman Catholics, however, conduct mass in local languages, and their rituals, while also ceremonial, are less reliant on icons.
The Greek Orthodox Church, part of Eastern Christianity, developed in the Eastern Roman Empire, maintaining many ancient Christian traditions. The Roman Catholic Church evolved in Western Europe, adapting to various cultural and historical influences distinct from the East.
Greek Orthodox theology emphasizes mysticism and theosis (deification), with a focus on experiential faith. Roman Catholics, while sharing many core Christian beliefs, place more emphasis on doctrinal teachings and the role of the Church in interpreting Scripture.
The Greek Orthodox Church has historically been associated with Greek and Eastern European cultures, influencing its practices and customs. Roman Catholics have a broader global presence, with a significant impact on Western culture and international politics.
