Phyletism
The principle of autonomy for national churches in Eastern Orthodoxy. It arose after the destruction of Constantinople in 1453 and gave autonomy to the various churches of the Byzantine Rite. Each national church was to be independent of the ecclesiastical control of the Patriarchate of Constantinople. See Byzantine Rite.
