The Eastern Orthodox Church is a Christian body whose adherents are largely based in the Middle East (particularly Syria, Lebanon, Jordan, Israel, and Palestine) and Turkey, Eastern Europe and the Caucasus (Georgia, Abkhazia, Ossetia etc.), with a growing presence in the Western world. Eastern Orthodox Christians accept the decisions of the first seven ecumenical councils.

Eastern Orthodox Christianity identifies itself as the original Christian church (see early centers of Christianity) founded by Christ and the Apostles, and traces its lineage back to the early Church through the process of apostolic succession and unchanged theology and practice. Distinguishing characteristics of the Eastern Orthodox Church include the Byzantine Rite (shared with some Eastern Catholic Churches) and an emphasis on the continuation of Holy Tradition, which it holds to be apostolic in nature.

The Eastern Orthodox Church is organized into self-governing jurisdictions along geographical, national, ethnic or linguistic lines. Eastern Orthodoxy is thus made up of fourteen or sixteen autocephalous bodies. Smaller churches are autonomous and each have a mother church that is autocephalous.

All Eastern Orthodox are united in doctrinal agreement with each other, though a few are not in communion at present, for non-doctrinal reasons. This is in contrast to the Catholic Church and its various churches. Members of the latter are all in communion with each other, parts of a top-down hierarchy (see primus inter pares).

The Eastern Orthodox reject the Filioque clause as heresy, in sharp contrast with the majority of Catholics. Yet some Catholics who are not in communion with the Catholic Church side with the Eastern Orthodox here and reject this teaching, putting them in theological disagreement with the others.

It may also be noted that the Church of Rome was once in communion with the Eastern Orthodox Church, but the two were split after the East–West Schism and thus it is no longer in communion with the Eastern Orthodox Church.

It is estimated that there are approximately 240 million Eastern Orthodox Christians in the world.[note 2] Today, many adherents shun the term "Eastern" as denying the church's universal character. They refer to Eastern Orthodoxy simply as the Orthodox Church.[8]

Oriental Orthodoxy refers to the churches of Eastern Christian tradition that keep the faith of the first three ecumenical councils of the undivided Christian Church: the First Council of Nicaea (AD 325), the First Council of Constantinople (381) and the Council of Ephesus (431), while rejecting the dogmatic definitions of the Council of Chalcedon (451). Hence, these churches are also called the Old Oriental churches. They comprise the Coptic Orthodox Church, the Eritrean Orthodox Tewahedo Church, the Ethiopian Orthodox Tewahedo Church, the Syriac Orthodox Church and the Armenian Apostolic Church.

Oriental Orthodoxy developed in reaction to Chalcedon on the eastern limit of the Byzantine Empire and in Egypt, Syria and Mesopotamia. In those locations, there are also Eastern Orthodox patriarchs, but the rivalry between the two has largely vanished in the centuries since the schism.

Historically, the Church of the East was the widest reaching branch of Eastern Christianity, at its height spreading from its heartland in Persian-ruled Assyria to the Mediterranean, India, and China. Originally the only Christian church recognized by Zoroastrian-led Sassanid Persia (through its alliance with the Lakhmids, the regional rivals to the Byzantines and its Ghassanid vassal), the Church of the East declared itself independent of other churches in 424 and over the next century became affiliated with Nestorianism, a Christological doctrine advanced by Nestorius, Patriarch of Constantinople from 428 to 431, which had been declared heretical in the Roman Empire. Thereafter it was often known, possibly inaccurately, as the Nestorian Church in the West. Surviving a period of persecution within Persia, the Church of the East flourished under the Abbasid Caliphate and branched out, establishing dioceses throughout Asia. After another period of expansion under the Mongol Empire, the church went into decline starting in the 14th century, and was eventually largely confined to its founding Assyrian adherent's heartland in the Assyrian homeland, although another remnant survived on the Malabar Coast of India.

In the 16th century, dynastic struggles sent the church into schism, resulting in the formation of two rival churches: The Chaldean Catholic Church, which entered into communion with Rome as an Eastern Catholic Church, and the Assyrian Church of the East. The followers of these two churches are almost exclusively ethnic Assyrians. In India, the local Church of the East community, known as the Saint Thomas Christians, experienced its own rifts as a result of Portuguese influence.

The Assyrian Church of the East emerged from the historical Church of the East, which was centered in Mesopotamia/Assyria, then part of the Persian Empire, and spread widely throughout Asia. The modern Assyrian Church of the East emerged in the 16th century following a split with the Chaldean Church, which later entered into communion with Rome as an Eastern Catholic Church.

The Church of the East was associated with the doctrine of Nestorianism, advanced by Nestorius, Patriarch of Constantinople from 428 to 431, which emphasized the disunion between the human and divine natures of Jesus. Nestorius and his doctrine were condemned at the Council of Ephesus in 431, leading to the Nestorian Schism in which churches supporting Nestorius split from the rest of Christianity.

Many followers relocated to Persia and became affiliated with the local Christian community there. This community adopted an increasingly Nestorian theology and was thereafter often known as the Nestorian Church. As such, the Church of the East accepts only the first two ecumenical councils of the undivided Church—the First Council of Nicaea and the First Council of Constantinople—as defining its faith tradition, and rapidly took a different course from other Eastern Christians.

The Church of the East spread widely through Persia and into Asia, being introduced to India by the 6th century and to the Mongols and China in the 7th century. It experienced periodic expansion until the 14th century, when the church was nearly destroyed by the collapse of the Mongol Empire and the conquests of Timur. By the 16th century it was largely confined to Iraq, northeast Syria, southeast Turkey, northwest Iran and the Malabar Coast of India (Kerala). The split of the 15th century, which saw the emergence of separate Assyrian and Chaldean Churches, left only the former as an independent sect. Additional splits into the 20th century further affected the history of the Assyrian Church of the East.

The Saint Thomas Christians are an ancient body of Christians on the southwest coast of India who trace their origins to the evangelical activity of Thomas the Apostle in the 1st century.[9] By the 5th century the Saint Thomas Christians were part of the Church of the East, or Nestorian Church. Until the middle of the 17th century and the arrival of the Portuguese, the Thomas Christians were all one in faith and rite. Thereafter, divisions arose among them, and consequently they are today of several different rites.

The twenty-three Eastern Catholic Churches are in communion with the Holy See at the Vatican despite being rooted in the theological and liturgical traditions of Eastern Christianity. These churches were originally part of the Orthodox East, but have since been reconciled to the Roman Church.

Many of these churches were originally part of one of the above families and so are closely related to them by way of ethos and liturgical practice. As in the other Eastern churches, married men may become priests, and parish priests administer the mystery of confirmation to newborn infants immediately after baptism, via the rite of chrismation; the infants are then administered Holy Communion.

The Syro-Malabar Church, which is part of the Saint Thomas Christian community in India, follows East Syriac traditions and liturgy. Other Saint Thomas Christians of India, who were originally of the same East Syriac tradition, passed instead to the West Syriac tradition and now form part of Oriental Orthodoxy (some from the Oriental Orthodox in India united with the Catholic Church in 1930 and became the Syro-Malankara Catholic Church). The Maronite Church claims never to have been separated from Rome, and has no counterpart Orthodox Church out of communion with the Pope. It is therefore inaccurate to refer to it as a "Uniate" Church. The Italo-Albanian Catholic Church has also never been out of communion with Rome, but, unlike the Maronite Church, it resembles the liturgical rite of the Eastern Orthodox Church.

The Church of the Cross of the Lord is located in Kremenets and is part of the Ukrainian Lutheran Church, which uses the Byzantine Rite.

In addition to these four mainstream branches, there are a number of much smaller groups which originated from disputes with the dominant tradition of their original areas. Most of these are either part of the more traditional Old Believer movement, which arose from a schism within Russian Orthodoxy, or the more radical Spiritual Christianity movement. The latter includes a number of diverse "low-church" groups, from the Bible-centered Molokans to the anarchic Doukhobors to the self-mutilating Skoptsy. None of these groups are in communion with the mainstream churches listed above, aside from a few Old Believer parishes in communion with the Russian Orthodox Church Outside Russia. There are also national dissidents, where ethnic groups want their own nation-church, such as the Macedonian Orthodox Church and the Montenegrin Orthodox Church; both are domiciles of the Serbian Orthodox Church. There are also some Reformed Churches which share characteristics of Eastern Christianity, to varying extents.

Starting in the 1920s, parallel hierarchies formed in opposition to local Orthodox churches over ecumenism and other matters. These jurisdictions sometimes refer to themselves as being "True Orthodox". In Russia, underground churches formed and maintained solidarity with the Russian Orthodox Church Outside Russia until the late 1970s. There are now traditionalist Orthodox in every area, though in Asia and the Middle East their presence is negligible.

Protestant Eastern Christianity comprises a collection of heterogeneous Protestant denominations which are mostly the result of Protestant Churches adopting reformational variants of Orthodox Christian liturgy and worship.[10][11] Some others are the result of reformations of Orthodox Christian beliefs and practices, inspired by the teachings of Western Protestant missionaries.[12] Denominations of this category include the Ukrainian Lutheran Church, St. Thomas Evangelical Church of India, Believers Eastern Church, Evangelical Orthodox Church, etc.

Byzantine Rite Lutheranism arose in the Ukrainian Lutheran Church around 1926.[2] It sprung up in the region of Galicia and its rites are based on the Liturgy of Saint John Chrysostom.[6][7] The church suffered persecution under the Communist régime, which implemented a policy of state atheism.[13]

At a meeting in Balamand, Lebanon, in June 1993, the Joint International Commission for the Theological Dialogue between the Catholic Church and the Orthodox Church declared that these initiatives that "led to the union of certain communities with the See of Rome and brought with them, as a consequence, the breaking of communion with their Mother Churches of the East … took place not without the interference of extra-ecclesial interests";[18] and that what has been called "uniatism" "can no longer be accepted either as a method to be followed nor as a model of the unity our Churches are seeking" (section 12).

At the same time, the Commission stated:

• 3) Concerning the Eastern Catholic Churches, it is clear that they, as part of the Catholic Communion, have the right to exist and to act in response to the spiritual needs of their faithful.
• 16) The Oriental Catholic Churches who have desired to re-establish full communion with the See of Rome and have remained faithful to it, have the rights and obligations which are connected with this communion.
• 22) Pastoral activity in the Catholic Church, Latin as well as Oriental, no longer aims at having the faithful of one Church pass over to the other; that is to say, it no longer aims at proselytizing among the Orthodox. It aims at answering the spiritual needs of its own faithful and it has no desire for expansion at the expense of the Orthodox Church. Within these perspectives, so that there will be no longer place for mistrust and suspicion, it is necessary that there be reciprocal exchanges of information about various pastoral projects and that thus cooperation between bishops and all those with responsibilities in our Churches, can be set in motion and develop.
