Organization of the Eastern Orthodox ChurchThe Eastern Orthodox Church, officially the Orthodox Catholic Church, is a communion composed of up to seventeen separate autocephalous (self-governing) hierarchical churches that profess Eastern Orthodoxy and recognise each other as canonical (regular) Eastern Orthodox Christian churches. Each constituent church is self-governing; its highest-ranking bishop called the primate (a patriarch, a metropolitan or an archbishop) reports to no higher earthly authority. Each regional church is composed of constituent eparchies (or dioceses) ruled by bishops.
Old BelieversOld Believers or Old Ritualists are Eastern Orthodox Christians who maintain the liturgical and ritual practices of the Russian Orthodox Church as they were before the reforms of Patriarch Nikon of Moscow between 1652 and 1666. Resisting the accommodation of Russian piety to the contemporary forms of Greek Orthodox worship, these Christians were anathematized, together with their ritual, in a Synod of 1666–67, producing a division in Eastern Europe between the Old Believers and those who followed the state church in its condemnation of the Old Rite.
SynodA synod (ˈsɪnəd) is a council of a Christian denomination, usually convened to decide an issue of doctrine, administration or application. The word synod comes from the σύνοδος ˈsinoðos, meaning "assembly" or "meeting"; the term is analogous with the Latin word concilium meaning "council". Originally, synods were meetings of bishops, and the word is still used in that sense in Catholicism, Oriental Orthodoxy and Eastern Orthodoxy. In modern usage, the word often refers to the governing body of a particular church, whether its members are meeting or not.
Tsarist autocracyTsarist autocracy (tsarskoye samoderzhaviye), also called Tsarism, was a form of absolute monarchy localised with the Grand Duchy of Moscow and its successor states the Tsardom of Russia and the Russian Empire. In it, the Tsar possessed in principle authority and wealth, with more power than constitutional monarchs counterbalanced by legislative authority, as well as a more religious authority than Western monarchs. The institution originated during the time of Ivan III (1462−1505) and was abolished after the Russian Revolution of 1917.
