Orthodox Eastern Church - community of Christian churches whose chief strength is in the Middle East and E Europe. Their members number over 250 million worldwide. The Orthodox agree doctrinally in accepting as ecumenical the first seven councils (see council, ecumenical) and in rejecting the jurisdiction of the bishop of Rome (the pope). This repudiation of the papal claims is the principal point dividing the Orthodox from Roman Catholics. Eastern Christians who have returned to communion with the pope are called Eastern Catholics, or Uniates; in every respect apart from this obedience to Rome, they resemble their Orthodox counterparts. This use of the terms Catholic (obeying the pope) and Orthodox (belonging to one of the Orthodox churches) is not technical, for both groups call themselves both Catholic and Orthodox (see catholic church). The word Orthodox became current at the time of the defeat (753) of iconoclasm in Constantinople. Orthodox acceptance of the seven councils resulted in the exclusion from their communion, on grounds of heresy, of the Nestorian, Jacobite, Coptic, and Armenian churches; it also involves holding a sacramental doctrine of grace ex opere operato (see grace) and of veneration of the Virgin Mary, two points differentiating the Orthodox from Protestants.

Ritual and Liturgy

The ritual that developed at the patriarchate of Constantinople—known as the Byzantine rite—gradually replaced other local rites in the Orthodox East, and after the 13th cent. became, with local variations and translations, the standard of Orthodox worship. It is sometimes called the Greek rite, because the original language was Greek, but the liturgy has been adapted into Slavonic, Arabic, Estonian, and many other languages. The liturgy is not usually celebrated daily as in the West, and it is always sung. Leavened bread is used in the Eucharist, and communion is given to laymen in both kinds (i.e., both bread and wine). Infants receive communion and confirmation. The other sacraments are similar to those of the Latin rite, except in details; e.g., confirmation is conferred by priests. The frequency of confession varies in the different self-governing churches. The church buildings are generally square, with a solid sanctuary screen covered with icons (iconostasis) (for the style, see Byzantine art and architecture). Parish priests may marry prior to ordination; monks and bishops may not marry.

Church Government

The old mode of government was the patriarchate (see patriarch), but now for the most part the churches, all of which are self-governing, are each governed by a holy synod, a board of bishops and laymen, often appointed by the government; where the head of the church is called patriarch, he is often only the moderator of the synod. The number of Orthodox churches recognizing one another as such is indefinite because of the fluid state of the relations of Orthodox bishops in countries to which communicants have emigrated.

There are many churches apart from those directly under the patriarchs. A unique, ancient church is that of Mt. Sinai, made up of the monastery of St. Catherine and its subject houses. The archbishop is also abbot. The monastic community of Mt. Athos in Greece is of special interest.

The Patriarchs and Churches

The four ancient patriarchates enjoy the highest prestige. The patriarchate of Constantinople, having the primacy of honor after Rome, was set up when the Eastern capital was established; it included Asia Minor and the Balkan Peninsula. From the time of Justinian I the emperor controlled the patriarch absolutely. The patriarch was freer under the Turks, who gave him civil and religious jurisdiction over all the Orthodox within the Turkish Empire. The patriarch of Constantinople never succeeded in establishing jurisdiction in the East comparable to that of the pope in the West. First the Russians, then the Greeks and the Balkan countries set up autonomous churches, always opposed by the patriarch, especially in the case of Bulgaria. In republican Turkey the patriarch rules a remnant only, although some modern Orthodox churches in North and South America, Australia, and N Europe are under his direct control. The Orthodox patriarchates of Alexandria and Antioch are minority churches (for the corresponding separated churches, see Copts; Jacobite Church), as is the patriarchate of Jerusalem. The patriarch represents Orthodox interests in the shrines.

There are seven national churches, each the traditional patriotic church of the people. The Church of Cyprus has been autonomous since the Council of Ephesus. The Church of Georgia is also ancient. In the 19th cent. it was absorbed by the Russian church but in 1917 resumed its autonomy. The head of the Georgian Church is titled catholicos.

The Russian Orthodox Church, the largest of the Orthodox churches, was led first by the metropolitan of Kiev, under Constantinople. The see was moved to Moscow, and in 1589 a new patriarchate was set up under the czar. The language of the ritual is Church Slavonic. In 1721, Peter the Great (Peter I) abolished the patriarchate and established a synod, which he controlled through its lay procurator. In 1917 the patriarchate was revived, just before the Bolshevik Revolution began the weakening of the whole church structure. In the disturbances of the revolution many priests and bishops were killed or exiled. Churches were plundered of their sacred vessels, and seminaries were closed. In World War II, however, the government consented (1943) to the reopening of churches and to the election of a patriarch (the first since 1925). The new patriarch and his successors were loyal to the Communist government. As the Soviet Union annexed lands after 1939, the local Orthodox churches disappeared; the same was true of Catholic churches of the Eastern rites, and thus it was announced that the Byzantine-rite Catholics of Ukraine and Ruthenia had united with the Russian Orthodox.

Under Mikhail Gorbachev, the patriarch of the Russian Orthodox Church was received (1988) at the Kremlin, the first such reception since World War II. Gorbachev oversaw a period of improved relations with the Orthodox Church, granting it legal status, returning relics seized by the state in 1920, and lifting other restrictions on worship. Since the end of the Soviet Union the church has seen enormous growth in Russia, and in 1997 it (along with other religions recognized under Soviet rule) was given special rights and legal exemptions.

The self-governing Church of Greece dates from the Greek War of Independence. It is the state church and legally much favored. The patriarch at Belgrade heads the Church of Serbia, which suffered restrictions under the Communist government of Yugoslavia and developed a strong nationalist bent in the 1990s during the breakup of Yugoslavia. The Church of Bulgaria was severed from communion by the ancient patriarchates in the 19th cent., but the Russian church recognized it. Its ruler is an exarch. The Romanian Orthodox Church has a patriarch at Bucharest; it was probably the most carefully organized of the Orthodox churches. After 1945 the government announced that the Roman Catholic dioceses of the Romanian rite had been annexed by the Orthodox church; the status of these dioceses and their property has become a source of tension in the post-Communist era.

Other Orthodox churches are minority denominations of recent creation. The Albanian Orthodox Church suffered considerably under Italian rule during World War II, as well as under Communist rule since then. The Orthodox churches of Finland and of Poland, founded after World War I, lost most of their members when the eastern sections of the countries were repossessed by the Soviet Union in World War II. The Japanese Orthodox Church became autonomous under government pressure (1939). It had its origin in a Russian mission founded in 1860.

There are a number of autonomous Orthodox groups that began in emigration. Thus in the United States there have been separate hierarchies of Greeks, Russians, and others, sometimes in communion with each other. There have been many efforts to establish a single American Orthodox church, but no union has been effected. In 1950 several Eastern Orthodox denominations joined with Protestant groups in the formation of the National Council of the Churches of Christ in the United States of America; almost all Orthodox churches in America are now members.

With the collapse of Communist rule in the countries of E Europe during the late 1980s and early 1990s, their Orthodox churches revived and gained new members. Following the establishment in 1991 of the Ukrainian Orthodox Church under the Russian patriarch, a breakaway church emerged and demanded independence from Moscow, but Constantinople refrained from endorsing the break. Constantinople's recognition in 1996 of Estonia's church as under its, instead of Russian, oversight led to strain between it and the Russian church.

Relations with Rome and the West

The relations between the Orthodox and the Western Church have been full of misunderstandings, which became grave as political and cultural ties loosened after the 5th cent. There were breaks between Constantinople and Rome in the 9th cent. (see Photius) and in 1054 (see Leo IX, Saint), but the main obstacle to reconciliation was the conduct of the Crusades, especially the Fourth Crusade (when the Crusaders seized Constantinople), since the whole of Western Christendom, most of all the pope, was inevitably blamed. In 1274 there was an attempt at reunion (Second Council of Lyons), and in 1439 another (see Ferrara-Florence, Council of); the second was repudiated (1472) by Constantinople.

In the Middle Ages the points at issue were papal authority, matters of worship and discipline, and the addition of the filioque to the Nicene Creed (see creed1). There have been fractional reunions, notably the Union of Brest-Litvosk
