What was a central argument during the Great East-West Schism?

The central argument during the Great East-West Schism, which occurred in 1054, primarily revolved around the authority of the Pope. This schism marked a significant division between the Roman Catholic Church in the West and the Eastern Orthodox Church. The Western Church upheld the Pope as the supreme authority over all Christians, claiming that he held direct succession from Saint Peter. In contrast, the Eastern Church rejected this notion, favoring a conciliar model of governance where the patriarchs and bishops collectively made decisions without a single figure holding absolute power over the Church.

The disagreements extended beyond mere authority; they were also influenced by theological, cultural, and political factors. However, the authority of the Pope was a cornerstone issue that symbolized broader divisions in ecclesiastical leadership and governance. Other aspects, such as the role of the laity, transubstantiation, and church funding, certainly played roles in ecclesiastical debates during this period, but they did not capture the essence of the split like the dispute over papal authority did. This central argument ultimately prompted long-lasting schisms that shaped the future of Christianity.
