What was the Great Schism? What factors brought it on? According to the New World Encyclopedia “The Great Schism, also called the East-West Schism, divided Christendom into Western (Latin) and Eastern (Greek) branches, which then became the Roman Catholic Church and the Eastern Orthodox Church, respectively. Usually dated to 1054, the Schism was the result of an extended period of tension and sometimes estrangement between then Latin and Greek Churches. The break became permanent after the sack of Byzantium Constantinople by Western Christians in 1204 during the Fourth Crusade.”
