The split between the Western and Greek Orthodox churches was rooted in differences in belief, language, and church structure.
The initial split between the Western and Greek Orthodox churches was primarily caused by a difference in creed, or belief. While the churches held similar beliefs, linguistic, cultural, and structural differences such as the use of Latin in the West and Greek in the East, clerical celibacy, and the extent of papal authority contributed to the schism. The Great Schism of 1054 marked the formal separation, with the East becoming the Eastern Orthodox Church and the West the Catholic Church.
