Eastern Orthodox Church

The Eastern Orthodox Church, also called the Orthodox 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 Roman Catholic Church—the Pope—but the Ecumenical Patriarch of Constantinople is recognized by them as ''primus inter pares'' ("first among equals"), which may be explained as a representative of the church. 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 Eastern and Southeastern Europe. The Eastern Orthodox Church officially calls itself the Orthodox Catholic Church.

Eastern Orthodox theology is based on holy tradition, which incorporates the dogmatic decrees of the seven ecumenical councils, the Scriptures, and the teaching of the Church Fathers. The church teaches that it is the one, holy, catholic and apostolic church established by Jesus Christ in his Great Commission, and that its bishops are the successors of Christ's apostles. It maintains that it practices the original Christian faith, as passed down by holy tradition. Its patriarchates, reminiscent of the pentarchy, and other autocephalous and autonomous churches, reflect a variety of hierarchical organisation. It recognizes seven major sacraments, of which the Eucharist is the principal one, celebrated liturgically in synaxis. The church teaches that through consecration invoked by a priest, the sacrificial bread and wine become the body and blood of Christ. The Virgin Mary is venerated in the Eastern Orthodox Church as the God-bearer, honored in devotions.

The churches of Constantinople, Alexandria, Jerusalem, and Antioch—except for some breaks of communion such as the Photian schism or the Acacian schism— shared communion with the Church of Rome until the East–West Schism in 1054. The 1054 schism was the culmination of mounting theological, political, and cultural disputes, particularly over the authority of the pope, between those churches. Before the Council of Ephesus in AD 431, the Church of the East also shared in this communion, as did the various Oriental Orthodox Churches before the Council of Chalcedon in AD 451, all separating primarily over differences in Christology.

The Eastern Orthodox Church is the primary religious denomination in Belarus, Bulgaria, Cyprus, Georgia, Moldova, Montenegro, North Macedonia, Romania, Russia, Serbia, Ukraine, and Greece; in the latter case it is additionally responsible for governing the autonomous region of the monastic community of Mount Athos. The majority of Eastern Orthodox Christians live mainly in Southeast and Eastern Europe, Siberia, and the Russian Far East. Roughly half of Eastern Orthodox Christians live in the post-Soviet states, mostly Russia. There are also communities in the former Byzantine regions of Africa, the Eastern Mediterranean, and in the Middle East, which are decreasing due to forced migration driven by increased religious persecution. Eastern Orthodox communities are also present in many other parts of the world, particularly North America, Western Europe, and Australia, formed through diaspora, conversions, and missionary activity.

Name and characteristics

Definition

The Eastern Orthodox Church is defined as the Eastern Christians which recognize the seven ecumenical councils and usually are in communion with the Ecumenical Patriarchate, the Patriarchate of Alexandria, the Patriarchate of Antioch, and the Patriarchate of Jerusalem. The Eastern Orthodox churches "are defined positively by their adherence to the dogmatic definitions of the seven cumenicalcouncils, by the strong sense of not being a sect or a denomination but simply continuing the Christian church, and, despite their varied origins, by adherence to the Byzantine rite." Those churches are negatively defined by their rejection of papal immediate and universal supremacy. The seven ecumenical councils recognized by the Eastern Orthodox churches are: Nicaea I, Constantinople I, Ephesus, Chalcedon, Constantinople II, Constantinople III, and Nicaea II. Those churches consider the Quinisext Council "shar sthe ecumenical authority of Constantinople III. "By an agreement that appears to be in place in the asternOrthodox world, possibly the council held in 879 to vindicate the Patriarch Photius will at some future date be recognized as the eighth cumenicalcouncil" by the Eastern Orthodox Church.

Western Rite Orthodoxy exists both outside and inside Eastern Orthodoxy. Within Eastern Orthodoxy, it is practised by a vicariate of the Antiochian Orthodox church.

Name

In keeping with the church's teaching on universality and with the Nicene Creed, Eastern Orthodox authorities such as Raphael of Brooklyn have insisted that the full name of the church has always included the term "Catholic", as in "Holy Orthodox Catholic Apostolic Church".

The official name of the Eastern Orthodox Church is the "Orthodox Catholic Church". It is the name by which the church refers to itself and which is issued in its liturgical or canonical texts. Eastern Orthodox theologians refer to the church as catholic. This name and longer variants containing "Catholic" are also recognized and referenced in other books and publications by secular or non-Eastern Orthodox writers. The catechism of Philaret (Drozdov) of Moscow published in the 19th century is titled: ''The Longer Catechism of the Orthodox, Catholic, Eastern Church'' ().

The common name of the church, "Eastern Orthodox Church", is a shortened practicality that helps to avoid confusions in casual use.

From ancient times through the first millennium, Greek was the most prevalent shared language in the demographic regions where the Byzantine Empire flourished, and Greek, being the language in which the New Testament was written, was the primary liturgical language of the church. For this reason, the eastern churches were sometimes identified as "Greek" (in contrast to the "Roman" or "Latin" church, which used a Latin translation of the Bible), even before the Great Schism of 1054. After 1054, "Greek Orthodox" or "Greek Catholic" marked a church as being in communion with Constantinople, much as "Catholic" did for communion with the Catholic Church. In Hungarian, the church is still commonly called "Eastern Greek" (). This identification with Greek, however, became increasingly confusing with time. Missionaries brought Eastern Orthodoxy to many regions without ethnic Greeks, where the Greek language was not spoken. In addition, struggles between Rome and Constantinople to control parts of Southeastern Europe resulted in the conversion of some churches to the Catholic Church, which then also used "Greek Catholic" to indicate their continued use of the Byzantine rites. Today, many of those same churches remain, while a very large number of Eastern Orthodox are not of Greek national origin, and do not use Greek as the language of worship.

"Eastern", then, indicates the geographical element in the church's origin and development, while "Orthodox" indicates the faith, as well as communion with the Ecumenical Patriarchate of Constantinople. There are additional Christian churches in the east that are in communion with neither the Catholic Church nor the Eastern Orthodox Church, who tend to be distinguished by the category named "Oriental Orthodox". While the Eastern Orthodox Church continues officially to call itself "Catholic", for reasons of universality, the common title of "Eastern Orthodox Church" avoids casual confusion with the Roman Catholic Church.

Orthodoxy

The first known use of the phrase "the catholic Church" (''he katholike ekklesia'') occurred in a letter written about 110 AD from one Greek church to another ( Ignatius of Antioch to the Smyrnaeans). The letter states: "Wheresoever the bishop shall appear, there let the people be, even as where Jesus may be, there is the universal atholikeChurch." Thus, almost from the beginning, Christians referred to the Christian Church as the "one, holy, catholic (from the Greek καθολική, 'according to the whole, universal') and apostolic Church". The Eastern Orthodox Church claims that it is today the continuation and preservation of that same early church.

A number of other Christian churches also make a similar claim: the Roman Catholic Church, the Anglican Communion, the Assyrian Church and the Oriental Orthodox. In the Eastern Orthodox view, the Assyrians and Orientals left the Orthodox Church in the years following the Third Ecumenical Council of Ephesus (431) and the Fourth Ecumenical Council of Chalcedon (451), respectively, in their refusal to accept those councils' Christological definitions. Similarly, the churches in Rome and Constantinople separated in an event known as the East–West Schism, traditionally dated to the year 1054, although it was more a gradual process than a sudden break.

To all these churches, the claim to catholicity (universality, oneness with the ancient Church) is important for multiple doctrinal reasons that have more bearing internally in each church than in their relation to the others, now separated in faith. The meaning of holding to a faith that is true is the primary reason why anyone's statement of which church split off from which other has any significance at all; the issues go as deep as the schisms. The depth of this meaning in the Eastern Orthodox Church is registered first in its use of the word " Orthodox" itself, a union of Greek ''orthos'' ("straight", "correct", "true", "right") and '' doxa'' ("common belief", from the ancient verb δοκέω-δοκῶ which is translated "to believe", "to think", "to consider", "to imagine", "to assume").

The dual meanings of ''doxa'', with "glory" or "glorification" (of God by the church and of the church by God), especially in worship, yield the pair "correct belief" and "true worship". Together, these express the core of a fundamental teaching about the inseparability of belief and worship and their role in drawing the church together with Christ. The Bulgarian and all the Slavic churches use the title ''Pravoslavie'' (Cyrillic: Православие), meaning "correctness of glorification", to denote what is in English ''Orthodoxy'', while the Georgians use the title ''Martlmadidebeli''.

The term "Eastern Church" (the geographic east in the East–West Schism) has been used to distinguish it from western Christendom (the geographic West, which at first came to designate the Catholic communion, later also the various Protestant and Anglican branches). "Eastern" is used to indicate that the highest concentrations of the Eastern Orthodox Church presence remain in the eastern part of the Christian world, although it is growing worldwide. Orthodox Christians throughout the world use various ethnic or national jurisdictional titles, or more inclusively, the title "Eastern Orthodox", "Orthodox Catholic", or simply "Orthodox".

What unites Orthodox Christians is the catholic faith as carried through holy tradition. That faith is expressed most fundamentally in scripture and worship, and the latter most essentially through baptism and in the Divine Liturgy.

The lines of even this test can blur, however, when differences that arise are not due to doctrine, but to recognition of jurisdiction. As the Eastern Orthodox Church has spread into the west and over the world, the church as a whole has yet to sort out all the inter-jurisdictional issues that have arisen in the expansion, leaving some areas of doubt about what is proper church governance. Moreover, as in the ancient church persecutions, the aftermath of persecutions of Christians in communist nations has left behind some issues of governance and lapse piety that have yet to be completely resolved.

All members of the Eastern Orthodox Church profess the same faith, regardless of race or nationality, jurisdiction or local custom, or century of birth. Holy tradition encompasses the understandings and means by which that unity of faith is transmitted across boundaries of time, geography, and culture. It is a continuity that exists only inasmuch as it lives within Christians themselves. It is not static, nor an observation of rules, but rather a sharing of observations that spring both from within and also in keeping with others, even others who lived lives long past. The church proclaims the Holy Spirit maintains the unity and consistency of holy tradition to preserve the integrity of the faith within the church, as given in the scriptural promises.

The shared beliefs of Orthodoxy, and its theology, exist within holy tradition and cannot be separated from it, for their meaning is not expressed in mere words alone. Doctrine cannot be understood unless it is prayed. Doctrine must also be lived in order to be prayed, for without action, the prayer is idle and empty, a mere vanity, and therefore the theology of demons.

Catholicity

The Eastern Orthodox Church considers itself to be both orthodox and catholic. The doctrine of the Catholicity of the Church, as derived from the Nicene Creed, is essential to Eastern Orthodox ecclesiology. The term ''Catholicity of the Church'' ( Greek ) is used in its original sense, as a designation for the universality of the Christian Church, centered around Christ. Therefore, the Eastern Orthodox notion of catholicity is not centered around any singular see, unlike the Catholic Church which has one earthly center.
