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.

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

, 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 Jesus (AD 30 or 33), also referred to as Jesus Christ, Jesus of Nazareth, and many Names and titles of Jesus in the New Testament, other names and titles, was a 1st-century Jewish preacher and religious leader. He is the Jesus in Chris ...
. 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

Most of these churches were originally part of the Orthodox East, but have since been reconciled to the Latin 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

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.

"True Orthodox" churches

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 Egypt their presence is negligible.

and Orthodox Patriarch Athenagoras I has awoken the nearly 1,000-year hopes for Christian unity. Since the lifting of excommunications during the Paul VI and Athenagoras I meeting in Jerusalem there have been other significant meetings between Popes and Ecumenical Patriarchs of Constantinople. One of the most recent meetings was between Benedict XVI and Bartholomew I, who jointly signed the ''Common Declaration''. It states that "We give thanks to the Author of all that is good, who allows us once again, in prayer and in dialogue, to express the joy we feel as brothers and to renew ''our commitment to move towards full communion''". In 2013 Patriarch Bartholomew I attended the installation ceremony of the new Catholic Pope, Francis, which was the first time any Ecumenical Patriarch of Constantinople had ever attended such an installation. In 2019, Primate of the OCU Metropolitan of Kyiv and All Ukraine Epiphanius stated that "theoretically" the Orthodox Church of Ukraine and the Ukrainian Greek Catholic Church could in the future unite into a united church around the Kyiv throne.

, 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"; 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.


Migration trends

There has been a significant Christian migration in the 20th century from the Near East. Fifteen hundred years ago Christians were the majority population in today's Turkey, Iraq, Syria, Lebanon, Jordan, Palestine and Egypt. In 1914 Christians constituted 25% of the population of the Ottoman Empire. At the beginning of the 21st century Christians constituted 6–7% of the region's population: less than 1% in Turkey, 3% in Iraq, 12% in Syria, 39% in Lebanon, 6% in Jordan, 2.5% in Israel/Palestine and 15–20% in Egypt. As of 2011 Eastern Orthodox Christians are among the wealthiest Christians in the United States. They also tend to be better educated than most other religious groups in America, having a high number of graduate (68%) and post-graduate (28%) degrees per capita.

Today Arab Christians still play important roles in the Arab world, and Christians are relatively wealthy, well educated, and politically moderate.
