The Eastern Orthodox Church, also called the Orthodox Church and officially the Orthodox Catholic Church, is the second-largest Christian church, with approximately 220 million baptized members. It operates as a communion of autocephalous churches, each governed by its bishops via local synods. The church has no central doctrinal or governmental authority analogous to the head of the Catholic Church—the pope, although the Ecumenical Patriarch of Constantinople is recognized by them as primus inter pares. As one of the oldest surviving religious institutions in the world, the Eastern Orthodox Church has played a prominent role in the history and culture of Western Asia, the Caucasus, and Eastern and Southeastern Europe.
The 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.
Eastern Christianity comprises Christian traditions and church families that originally developed during classical and late antiquity in Western Asia, Asia Minor, Eastern Europe, Southeastern Europe, the Caucasus, Northeast Africa, the Fertile Crescent and the Malabar coast of South Asia, and ephemerally parts of Persia, Central Asia and the Far East. The term does not describe a single communion or religious denomination.
The term Greek Orthodox Church has three meanings. The broader meaning designates "the entire body of Orthodox (Chalcedonian) Christianity, sometimes also called 'Eastern Orthodox,' 'Greek Catholic,' or generally 'the Greek Church'". The narrower meaning designates "any of several independent churches within the worldwide communion of (Eastern) Orthodox Christianity that retain the use of the Greek language in formal ecclesiastical settings". The third is the Church of Greece, the Eastern Orthodox church operating within the modern borders of Greece.
The Patriarch of Antioch is a traditional title held by the bishop of Antioch. As the traditional "overseer" of the first gentile Christian community, the position has been of prime importance in Pauline Christianity from its earliest period. This diocese is one of the few for which the names of its bishops from the apostolic beginnings have been preserved. Today five churches use the title of patriarch of Antioch: one Oriental Orthodox ; three Eastern Catholic ; and one Eastern Orthodox.
The Greek Orthodox Patriarchate of Antioch, also known as the Antiochian Orthodox Church and legally as the RūmOrthodox Patriarchate of Antioch and All the East, is an autocephalous Melkite Greek Orthodox church within the wider communion of Eastern Orthodox Christianity and one of the historic Pentarchies. Headed by the Eastern Orthodox patriarch of Antioch, it considers itself the successor to the Christian community founded in Antioch by the Apostles Peter and Paul, and is the primary denomination of Arab Christians.
The Serbian Orthodox Church is one of the autocephalous Eastern Orthodox Christian churches.
The Bulgarian Orthodox Church, legally the Patriarchate of Bulgaria, is an autocephalous Eastern Orthodox jurisdiction based in Bulgaria. It is the oldest Slavic Orthodox church, with some 6 million members in Bulgaria and between 1.5 and 2 million members in a number of other European countries, Asia, the Americas, Australia, and New Zealand. It was recognized as autocephalous in 1945 by the Ecumenical Patriarchate of Constantinople.
The term Melkite, also written Melchite, refers to various Eastern Christian churches of the Byzantine Rite and their members originating in the Middle East. The term comes from the common Central Semitic root m-l-k, meaning "royal", and by extension "imperial" or loyal to the Byzantine Emperor. The term acquired religious connotations as denominational designation for those Christians who accepted imperial religious policies, based on Christological resolutions of the Council of Chalcedon (451).
The Catholic Church is the fourth largest religious congregation in Bulgaria, after Eastern Orthodoxy, Islam and Protestantism. Its roots in the country date to the Middle Ages and are part of the worldwide Catholic Church, under the spiritual leadership of the Pope in Rome.
The Macedonian Orthodox Church – Archdiocese of Ohrid, or simply the Macedonian Orthodox Church (MOC) or the Archdiocese of Ohrid (AO), is an autocephalous Eastern Orthodox church in North Macedonia. The Macedonian Orthodox Church claims ecclesiastical jurisdiction over North Macedonia, and is also represented in the Macedonian diaspora. The primate of the Macedonian Orthodox Church is Stefan Veljanovski, the Metropolitan of Skopje and Archbishop of Ohrid and Macedonia.
Eastern 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 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. Autocephalous churches choose their own primate. Autocephalous churches can have jurisdiction (authority) over other churches, some of which have the status of "autonomous" which means they have more autonomy than simple eparchies.
Religion in Bulgaria has been dominated by Christianity since its adoption as the state religion in 864. The dominant form of the religion is Eastern Orthodox Christianity within the fold of the Bulgarian Orthodox Church. During the Ottoman rule of the Balkans, Islam spread to the territories of Bulgaria, and it remains a significant minority today. The Catholic Church has roots in the country since the Middle Ages, and Protestantism arrived in the 19th century; both of them remain very small minorities. Today, a significant part of the Bulgarians are not religious, or believers who do not identify with any specific religion, and Bulgaria has been the cradle of some new religions, notably the Neo-Theosophical movement of Dunovism.
The History of the Eastern Orthodox Church is the formation, events, and transformation of the Eastern Orthodox Church through time.
In North Macedonia, the most common religion is Eastern Orthodox Christianity, practiced mainly by ethnic Macedonians, Serbians, Vlakhs, and Romanis. The vast majority of the Eastern Orthodox in the country belong to the Macedonian Orthodox Church, which declared autocephaly from the Serbian Orthodox Church in 1967.
In AD 1453, the city of Constantinople, the capital and last stronghold of the Byzantine Empire, fell to the Ottoman Empire. By this time Egypt had been under Muslim control for some seven centuries. Jerusalem had been conquered by the Rashidun Caliphate Muslims in 638, won back by Rome in 1099 under the First Crusade and then reconquered by Saladin's forces during the siege of Jerusalem in 1187. Later in the seventh Crusade, it was taken back by the Catholics once again. It was conquered by the Ottomans in 1517. Orthodoxy, however, was very strong in Russia which had recently acquired an autocephalous status; and thus Moscow called itself the Third Rome, as the cultural heir of Constantinople. Under Ottoman rule, the Greek Orthodox Church acquired power as an autonomous millet. The ecumenical patriarch was the religious and administrative ruler of the entire "Greek Orthodox nation", which encompassed all the Eastern Orthodox subjects of the Empire.
By the 10th century, Christianity had spread throughout much of Europe and Asia. The Church in England was becoming well established, with its scholarly monasteries, and the Roman Church and the Eastern Orthodox Church were continuing their separation, ultimately culminating in the Great Schism.
Christianity became the official religion of the Roman Empire when Emperor Theodosius I issued the Edict of Thessalonica in 380, which recognized the catholic orthodoxy of Nicene Christians in the Great Church as the Roman Empire's state religion. Most historians refer to the Nicene church associated with emperors in a variety of ways: as the catholic church, the orthodox church, the imperial church, the imperial Roman church, or the Byzantine church, although some of those terms are also used for wider communions extending outside the Roman Empire. The Eastern Orthodox Church, Oriental Orthodoxy, and the Catholic Church all claim to stand in continuity from the Nicene church to which Theodosius granted recognition.
Christianity is the predominant religion in Serbia. The Constitution of Serbia defines it as a secular state with guaranteed religious freedom. Eastern Orthodox Christians comprise 84.5% of country's population with 6,079,396 members. The Serbian Orthodox Church is the largest and traditional church of the country, adherents of which are overwhelmingly Serbs. Public schools in Serbia allow religious teaching, most commonly with the Serbian Orthodox Church. Serbian public holidays include the religious celebrations of Eastern Orthodox Christians. Other Orthodox Christian communities in Serbia include Montenegrins, Romanians, Macedonians and Bulgarians. The Catholic Church is prominent in north Vojvodina amongst the Hungarian minority. Protestantism is most largely found in Slovak populations within Bački Petrovac and Kovačica. Christianity first arrived in Serbia in the 9th century. It became state-religion in the 9th century when Serbia began to identify as a Christian country. In a 2011 census, 91.22% of Serbians identified as Christian.
