Oriental Orthodoxy by country

Oriental Orthodox Churches are the churches descended from those that rejected the Council of Chalcedon in 451. Despite the similar name, they are therefore a different branch of Christianity from the Eastern Orthodox. Oriental Orthodoxy consists of several autocephalous and autonomous jurisdictions holding a single set of beliefs and united in full communion. However, they each have their own separate rites, and there are significant differences between their respective practices. Thus, there is more internal diversity of practice among the Oriental Orthodox than among the Eastern Orthodox.
