Catholic ChurchThe Catholic Church, also known as the Roman Catholic Church, is the largest Christian church, with 1.3 billion baptized Catholics worldwide It is among the world's oldest and largest international institutions, and has played a prominent role in the history and development of Western civilization. The church consists of 24 sui iuris churches, including the Latin Church and 23 Eastern Catholic Churches, which comprise almost 3,500 dioceses and eparchies located around the world.
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.
AutocephalyAutocephaly (ɔːtəˈsɛfəli; from αὐτοκεφαλία, meaning "property of being self-headed") is the status of a hierarchical Christian church whose head bishop does not report to any higher-ranking bishop. The term is primarily used in Eastern Orthodox and Oriental Orthodox churches. The status has been compared with that of the churches (provinces) within the Anglican Communion. In the first centuries of the history of the Christian church, the autocephalous status of a local church was promulgated by canons of the ecumenical councils.
Latin ChurchThe Latin Church (Ecclesia Latina) is the largest autonomous (sui iuris) particular church within the Catholic Church, whose members constitute the vast majority of the 1.3 billion Christians in communion with the Pope in Rome. The Latin Church is one of 24 churches sui iuris in communion with the pope; the other 23 are referred to as the Eastern Catholic Churches, and have approximately 18 million members combined. The Latin Church is directly headed by the Pope in his role as the Bishop of Rome, whose cathedra as a bishop is located in the Archbasilica of Saint John Lateran in Rome, Italy.
Byzantine EmpireThe Byzantine Empire, also referred to as the Eastern Roman Empire, was the continuation of the Roman Empire primarily in its eastern provinces during Late Antiquity and the Middle Ages, when its capital city was Constantinople. It survived the fall of the Western Roman Empire in the 5th century AD and continued to exist until the fall of Constantinople to the Ottoman Empire in 1453. During most of its existence, the empire remained the most powerful economic, cultural, and military force in the Mediterranean world.
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.
Serbian Orthodox ChurchThe Serbian Orthodox Church (Srpska pravoslavna crkva) is one of the autocephalous (ecclesiastically independent) Eastern Orthodox Christian churches. The majority of the population in Serbia, Montenegro and the Republika Srpska entity of Bosnia and Herzegovina are members of the Serbian Orthodox Church. It is organized into metropolitanates and eparchies, located primarily in Serbia, Bosnia and Herzegovina, Montenegro, and Croatia. Other congregations are located in the Serb diaspora.
Primus inter paresPrimus inter pares is a Latin phrase meaning first among equals. It is typically used as an honorary title for someone who is formally equal to other members of their group but is accorded unofficial respect, traditionally owing to their seniority in office. Historically, the princeps senatus of the Roman Senate was such a figure and initially bore only the distinction that he was allowed to speak first during debate. Also, Constantine the Great was given the role of primus inter pares.
Eastern OrthodoxyEastern Orthodoxy, otherwise known as Eastern Orthodox Christianity or Byzantine Christianity, is one of the three main branches of Chalcedonian Christianity, alongside Roman Catholicism and Protestantism. Like the Pentarchy of the first millennium, the mainstream (or "canonical") Eastern Orthodox Church is organised into autocephalous churches independent from each other. In the 21st century, the number of mainstream autocephalous churches is seventeen; there also exist autocephalous churches unrecognized by those mainstream ones.
Episcopal seeAn episcopal see is, in a practical use of the phrase, the area of a bishop's ecclesiastical jurisdiction. Phrases concerning actions occurring within or outside an episcopal see are indicative of the geographical significance of the term, making it synonymous with diocese. The word see is derived from Latin sedes, which in its original or proper sense denotes the seat or chair that, in the case of a bishop, is the earliest symbol of the bishop's authority. This symbolic chair is also known as the bishop's cathedra.
