PatriarchatePatriarchate (πατριαρχεῖον, patriarcheîon) is an ecclesiological term in Christianity, designating the office and jurisdiction of an ecclesiastical patriarch. According to Christian tradition three patriarchates were established by the apostles as apostolic sees in the 1st century: Rome, Antioch, and Alexandria. Constantinople was added in the 4th century and Jerusalem in the 5th century. Eventually, together, these five were recognised as the pentarchy by the Council of Ephesus in 431.
Ecumenical Patriarch of ConstantinopleThe ecumenical patriarch (Οἰκουμενικός Πατριάρχης) is the archbishop of Constantinople (Istanbul) and New Rome, and primus inter pares (first among equals) among the heads of the several autocephalous churches which compose the Eastern Orthodox Church. The ecumenical patriarch is regarded as the representative and spiritual leader of the Eastern Orthodox Christians worldwide. The term ecumenical in the title is a historical reference to the Ecumene, a Greek designation for the civilised world, i.e.
EcumenismEcumenism (ɪˈkjuːməˌnɪzəm ; alternatively spelled oecumenism) - also called interdenominationalism, transdenominationalism, or ecumenicalism - is the concept and principle that Christians who belong to different Christian denominations should work together to develop closer relationships among their churches and promote Christian unity. The adjective ecumenical is thus applied to any interdenominational initiative that encourages greater cooperation and union among Christian denominations and churches.
Russian Orthodox ChurchThe Russian Orthodox Church (ROC; Russkaja pravoslavnaja cerkov’, abbreviated as РПЦ), alternatively legally known as the Moscow Patriarchate (Moskovský patriarhat), is an autocephalous Eastern Orthodox Christian church. It has 194 dioceses inside Russia. The primate of the ROC is the Patriarch of Moscow and all Rus'. The Christianization of Kievan Rus' commenced in 988 with the baptism of the Rus' Grand Prince of Kiev—Vladimir the Great—and his people by the clergy of the Ecumenical Patriarch of Constantinople.
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.
PatriarchThe highest-ranking bishops in Eastern Orthodoxy, Oriental Orthodoxy, the Catholic Church (above major archbishop and primate), the Hussite Church, Church of the East, and some Independent Catholic Churches are termed patriarchs (and in certain cases also popes – such as the Pope of Rome or Pope of Alexandria, and catholicoi – such as Catholicos Karekin II). The word is derived from Greek πατριάρχης (patriarchēs), meaning "chief or father of a family", a compound of πατριά (patria), meaning "family", and ἄρχειν (archein), meaning "to rule".
