when did the orthodox and catholic church split
East–West Schism The Eastâ€“West Schism, also called the Great Schism and the Schism of 1054, was the break of communion between what are now the Catholic Church and Eastern Orthodox churches, which has lasted since the 11th century.[1]
Hierarchy of the Catholic Church Three other of the pope's offices stem directly from his office as bishop of the Church of Rome. As the Latin Church owes its identity and development to its origins in the liturgical, juridical, and theological patrimony of Rome, the bishop of Rome is de facto the patriarch of the Latin Church. According to no less than Pope Benedict XVI, there has been much 'confusion' between the pope's primacy as patriarch of the western church and his primacy as first patriarch among equals, that this "failure to distinguish" between the roles and responsibilities of these two distinct positions lead in time to the "extreme centralization of the Catholic Church" and the schism between East and West.[31]
