They are organized similar to the Catholic Church since they originally were from the same church organization. After the separation of the Roman Empire (East and West) and Attila's move into Italy, Rome became the powerhouse for the Eastern Side and the Pope, who use to just represent Rome as the Patriarch, became the leading power of the East. Anyhow, the Orthodox church with the Byzantine Empires capitol being in Constantinople had there leading patriarch in Constantinople, since that was the strongest church in their area of influence. After the expansion of the Orthodox side of the Christain faith to the Rusk lands, the main areas of the faith of the Rusk was split between Kiev, Novos..., and later Moscow. Once Moscow took both of these areas over, it became where the most powerful of the Russian Patriarchs resided, the Patriarch of Moscow. With the advent of the Russian Empire this Patriach more or less became the figurehead of the Orthodox faith in Russia's area of influece. However after the destruction of many of the churches by the Soviet State, the church leadership became less centralized. Therefore the leadership of the church today has yet to ascertain a complete leader but the Moscovian Patriarch is the leader by default. At this time as in the Catholic Church in the Reframation, it is having a large sum of divisions in the church because of church policies. An example of this is the Moscow Patriarch having dispute with a leader in the south of Russia on some of their interpretations of the Bible and Orthodox stuff. One example of this would be the belief that only Orthodox people can marry in the Orthodox church and the Church's blessing.
