Ecclesiastical differences between the Catholic Church and the Eastern Orthodox Church information
Catholic–Orthodox ecclesiastical differences
For theological differences between the two churches, see Theological differences between the Catholic Church and the Eastern Orthodox Church.
Several differences exist within the organizational structures and governance of the Catholic Church and the Eastern Orthodox Church. These are distinguished from theological differences which are differences in dogma and doctrine. A number of disagreements over matters of ecclesiology developed slowly between the Western and Eastern wings of the State church of the Roman Empire centered upon the cities of Rome (considered to have fallen in 476) and New Rome/Constantinople (also considered to have "fallen" in 1453) respectively. The disputes were a major factor in the formal East-West Schism between Pope Leo IX and Patriarch Michael I in 1054 and are largely still unresolved between the churches today.
