when did roman catholic and eastern orthodox 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 had lasted until the 11th century.[1] The Schism was the culmination of theological and political differences between the Christian East and West which had developed over the preceding centuries.
