Eastern Orthodoxy

A Greek Orthodox Church (Greek: Ἑλληνορθόδοξη Ἐκκλησία, romanized: Ellinorthódoxi Ekklisía, IPA: [elinorˈθoðoksi ekliˈsia]) is any of three classes of Christian churches, each associated in some way with Greek Christianity, Levantine Arabic-speaking Christians or more broadly the rite used in the Eastern Roman Empire:

• The broader meaning refers to "the entire body of Orthodox (Chalcedonian) Christianity, sometimes also called 'Eastern Orthodox', 'Greek Catholic', or generally 'the Greek Church'".
• A second, narrower meaning refers to "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". In this sense, the Greek Orthodox Churches are the Ecumenical Patriarchate of Constantinople and its dependencies, the Patriarchates of Alexandria, Antioch and Jerusalem, the Church of Greece and the Church of Cyprus.
• The third meaning refers to the Church of Greece, an Eastern Orthodox Church operating within the modern borders of Greece.

In Christian iconography, Christ Pantocrator (Ancient Greek: Χριστὸς Παντοκράτωρ, lit. 'Christ the Almighty') is a specific depiction of Christ. Pantocrator or Pantokrator, literally 'ruler of all', but usually translated as 'almighty' or 'all-powerful', is derived from one of many names of God in Judaism.

The Pantokrator is largely an Eastern Orthodox, Eastern Catholic or Eastern Lutheran theological conception and is less common under that name in Latin Catholicism and Western Lutheranism. In the West, the equivalent image in art is known as Christ in Majesty, which developed a rather different iconography. Christ Pantocrator has come to suggest Christ as a benevolent, though also stern and all-powerful, judge of humanity.

A pastor (abbreviated to "PsPr", "Pstr.", "Ptr." or "Psa" (both singular), or "Ps" (plural)) is the leader of a Christian congregation who also gives advice and counsel to people from the community or congregation. In Lutheranism, Catholicism, Eastern Orthodoxy, Oriental Orthodoxy and Anglicanism, pastors are always ordained. In Methodism, pastors may be either licensed or ordained.

The New Testament typically uses the words "bishops" (Acts 20:28) and "presbyter" (1 Peter 5:1) to indicate the ordained leadership in early Christianity. However, the word "pastor" (ποιμήν/poimēn) is only used one time to describe church leadership in the New Testament in Ephesians 4:11 which says, "that some would be apostles, some prophets, some evangelists, some pastors and teachers" (NRSV). Peter instructs church leadership using the verb, "to tend the flock' (lit. 'to shepherd,' ποιμαίνω/poimainō) of God that is in your charge, exercising the oversight (1 Peter 5:2 NRSV). The words "bishop" and "presbyter" were sometimes used in an interchangeable way, such as in Titus 1:5-6. However, there is ongoing dispute between branches of Christianity over whether there are two ordained classes (presbyters and deacons), or three (bishops, priests, and deacons). The first view is affirmed by some Presbyterians. On the other hand, Christians of the Roman Catholic, Persian, Eastern Orthodox, Oriental Orthodox, Moravian, Scandinavian Lutheran, Anglican, Old Catholic and other Presbyterian traditions maintain the latter view, with all but the Presbyterians affirming the doctrine of apostolic succession.

The Apostolic Autocephalous Orthodox Church of Georgia (Georgian: საქართველოს სამოციქულო ავტოკეფალური მართლმადიდებელი ეკლესია, romanized: sakartvelos samotsikulo avt'ok'epaluri martlmadidebeli ek'lesia), commonly known as the Georgian Orthodox Church or the Orthodox Church of Georgia, is an autocephalous Eastern Orthodox church in full communion with the other churches of Eastern Orthodoxy. It is Georgia's dominant religious institution, and a majority of Georgian people are members. The Orthodox Church of Georgia is one of the oldest churches in the world. It asserts apostolic foundation, and that its historical roots can be traced to the early and late Christianization of Iberia and Colchis by Andrew the Apostle in the 1st century AD and by Saint Nino in the 4th century AD, respectively. As in similar autocephalous Eastern Orthodox Christian churches, the church's highest governing body is the holy synod of bishops. The church is headed by the Patriarch of All Georgia, Ilia II, who was elected in 1977.

Eastern Orthodox Christianity was the state religion throughout most of Georgia's history until 1921, when the country, having declared independence from Russia in 1918, was occupied by the Red Army during the Soviet invasion of Georgia, becoming part of the Soviet Union. The current Constitution of Georgia recognizes the special role of the Georgian Orthodox Church in the country's history, but also stipulates the independence of the church from the state. Government relations are further defined and regulated by the Concordat of 2002.

Apostolic succession is the method whereby the ministry of the Christian Church is considered by some Christian denominations to be derived from the apostles by a continuous succession, which has usually been associated with a claim that the succession is through a series of bishops. Those of the Catholic, Eastern Orthodox, Oriental Orthodox, Church of the East traditions maintain that a bishop's orders are neither regular nor valid without consecration through apostolic succession. These traditions do not always consider the episcopal consecrations of all of the other traditions as valid.

This series was seen originally as that of the bishops of a particular see founded by one or more of the apostles. According to historian Justo L. González, apostolic succession is generally understood today as meaning a series of bishops, regardless of see, each consecrated by other bishops, themselves consecrated similarly in a succession going back to the apostles. According to the Joint International Commission for Theological Dialogue Between the Catholic Church and the Orthodox Church, "apostolic succession" means more than a mere transmission of powers. It is succession in a church which witnesses to the apostolic faith, in communion with the other churches, witnesses of the same apostolic faith. The "see (cathedra) plays an important role in inserting the bishop into the heart of ecclesial apostolicity", but once ordained, the bishop becomes in his church the guarantor of apostolicity and becomes a successor of the apostles.

Sola scriptura (Latin for 'by scripture alone') is a Christian theological doctrine held by most Protestant Christian denominations, in particular the Lutheran and Reformed traditions, that posits the Bible as the sole infallible source of authority for Christian faith and practice. Sola scriptura is a formal principle of many Protestant Christian denominations, and one of the five solae theorized in the early 20th Century in attempts to characterize common ground in disparate Protestant theologies.

The Catholic Church considers it heresy and generally the Orthodox churches consider it to be contrary to the phronema of the Church. While the scriptures' meaning is mediated through many kinds of subordinate authority—such as the ordinary teaching offices of a church, the ecumenical creeds, councils of the Catholic Church, or even personal special revelation—sola scriptura in contrast rejects any infallible authority other than the Bible.

Orthodoxy (from Ancient Greek ὀρθοδοξία (orthodoxía) 'righteous/correct opinion') is adherence to a purported "correct" or otherwise mainstream- or classically accepted creed, especially in religion.

Orthodoxy within Christianity refers to acceptance of the doctrines defined by various creeds and ecumenical councils in antiquity, but different Churches accept different creeds and councils. Such differences of opinion have developed for numerous reasons, including language and cultural barriers. In the Christian world, Eastern Orthodoxy and Oriental Orthodoxy are sometimes referred to simply as "the Orthodox" or "Orthodoxy".

The Church of the East (Classical Syriac: ܥܕܬܐ ܕܡܕܢܚܐ ʿĒḏtā d-Maḏenḥā) or the East Syriac Church, also called the Church of Seleucia-Ctesiphon, the Persian Church, the Assyrian Church, the Babylonian Church, the Chaldean Church or the Nestorian Church, is one of three major branches of Eastern Nicene Christianity that arose from the Christological controversies in the 5th century and the 6th century, alongside that of Miaphysitism (which came to be known as the Oriental Orthodox Churches) and Chalcedonian Christianity (from which Catholicism, Eastern Orthodoxy and Protestantism would arise).

Having its origins in Mesopotamia during the time of the Parthian Empire, the Church of the East developed its own unique form of Christian theology and liturgy. During the early modern period, a series of schisms gave rise to rival patriarchates, sometimes two, sometimes three. In the latter half of the 20th century, the traditionalist patriarchate of the church underwent a split into two rival patriarchates, namely the Assyrian Church of the East and the Ancient Church of the East, which continue to follow the traditional theology and liturgy of the mother church. The Chaldean Catholic Church based in Iraq and the Syro-Malabar Church in India are two Eastern Catholic churches which also claim the heritage of the Church of the East.

The highest-ranking bishops in Eastern Orthodoxy, Oriental Orthodoxy, the Roman Catholic Church (above major archbishop and primate), the Hussite Church, Church of the East, and some Independent Catholic Churches are termed patriarchs (and in certain cases also popes – such as the pope of Rome or pope of Alexandria).

The word is derived from Greek πατριάρχης (patriarchēs), meaning "chief or father of a family", a compound of πατριά (patria), meaning "family", and ἄρχειν (archein), meaning "to rule".

In certain Christian denominations, holy orders are the ordained ministries of bishop, priest (presbyter), and deacon, and the sacrament or rite by which candidates are ordained to those orders. Churches recognizing these orders include the Catholic Church, the Eastern Orthodox (ιερωσύνη [hierōsynē], ιεράτευμα [hierateuma], Священство [Svyashchenstvo]), Oriental Orthodox, Anglican, Assyrian, Old Catholic, Independent Catholic and some Lutheran churches. Except for some Lutherans and some Anglicans, these churches regard ordination as a sacrament (the sacramentum ordinis).

Denominations have varied conceptions of holy orders. In some Lutheran and Anglican churches the traditional orders of bishop, priest and deacon are bestowed using ordination rites contained within ordinals. The extent to which ordination is considered sacramental in these traditions has, however, been a matter of some internal dispute. Baptists are among the denominations that do not consider ministry as being sacramental in nature and would not think of it in terms of "holy orders" as such. Historically, the word "order" (Latin ordo) designated an established civil body or corporation with a hierarchy, and ordinatio meant legal incorporation into an ordo. The word "holy" refers to the church. In context, therefore, a holy order is set apart for ministry in the church. Other positions, such as pope, patriarch, cardinal, monsignor, archbishop, archimandrite, archpriest, protopresbyter, hieromonk, protodeacon and archdeacon, are not sacramental orders but specialized ministries.
