Oriental Orthodox in the context of "Holy tradition"

An icon (from Ancient Greek εἰκών (eikṓn) 'image, resemblance') is a religious work of art, most commonly a painting, in the cultures of the Eastern Orthodox, Oriental Orthodox, Catholic, and Lutheran churches. The most common subjects include Jesus, Mary, saints, and angels. Although especially associated with portrait-style images concentrating on one or two main figures, the term also covers most of the religious images in a variety of artistic media produced by Eastern Christianity, including narrative scenes, usually from the Bible or the lives of saints.

Icons are most commonly painted on wood panels with egg tempera, but they may also be cast in metal or carved in stone or embroidered on cloth or done in mosaic or fresco work or printed on paper or metal, etc. Comparable images from Western Christianity may be classified as "icons", although "iconic" may also be used to describe the static style of a devotional image. In the Greek language, the term for icon painting uses the same word as for "writing", and Orthodox sources often translate it into English as icon writing.

A crozier or crosier (also known as a paterissa, pastoral staff, or bishop's staff) is a stylized staff that is a symbol of the governing office of a bishop or abbot and is carried by high-ranking prelates of Roman Catholic, Eastern Catholic, Eastern Orthodox, Oriental Orthodox, Malankara Mar Thoma Syrian Church, Church of South India and some Anglican, Lutheran, United Methodist and Pentecostal churches.

In Western Christianity the crozier typically takes the form of a shepherd's crook, a tool used to manage flocks of sheep and herds of goats. In Eastern Christianity, the crozier has two common forms: tau-shaped, with curved arms, surmounted by a small cross; or a pair of sculptured serpents or dragons curled back to face each other, with a small cross between them.

A Christian (/ˈkrɪstʃən, -tiən/ ) is a person who follows or adheres to Christianity, a monotheistic Abrahamic religion based on the life and teachings of Jesus Christ. Christians form the largest religious community in the world. The words Christ and Christian derive from the Koine Greek title Christós (Χριστός), a translation of the Biblical Hebrew term mashiach (מָשִׁיחַ) (usually rendered as messiah in English). While there are diverse interpretations of Christianity which sometimes conflict, they are united in believing that Jesus has a unique significance. The term Christian used as an adjective is descriptive of anything associated with Christianity or Christian churches, or in a proverbial sense "all that is noble, and good, and Christ-like."

According to a 2011 Pew Research Center survey, there were 2.3 billion Christians around the world, up from about 600 million in 1910. Today, about 37% of all Christians live in the Americas, about 26% live in Europe, 24% live in sub-Saharan Africa, about 13% live in Asia and the Pacific, and 1% live in the Middle East and North Africa. Christians make up the majority of the population in 158 countries and territories. 280 million Christians live as a minority. About half of all Christians worldwide are Catholic, while more than a third are Protestant (37%). Eastern Christians, including the Eastern Orthodox, Oriental Orthodox, and Church of the East, comprise 12% of the world's Christians. Other Christian groups make up the remainder. By 2050, the Christian population is expected to exceed 3 billion due to overall total fertility rate according to Pew Research Center. According to a 2012 Pew Research Center survey, Christianity will remain the world's largest religion in 2050, if current trends continue. In recent history, Christians have experienced persecution of varying severity, especially in the Middle-East, North Africa, East Asia, and South Asia.

The Eastern Catholic Churches or Oriental Catholic Churches, also known as the Eastern-Rite Catholic Churches, Eastern Rite Catholicism, or simply the Eastern Churches, are 23 Eastern Christian autonomous (sui iuris) particular churches of the Catholic Church in full communion with the pope in Rome. Although they are distinct theologically, liturgically, and historically from the Latin Church, they are all in full communion with it and with each other. Eastern Catholics are a minority within the Catholic Church; of the 1.3 billion Catholics in communion with the pope, approximately 18 million are members of the Eastern churches. The largest numbers of Eastern Catholics are found in Eastern Europe, Eastern Africa, the Middle East, and India. As of 2022, the Syro-Malabar Church is the largest Eastern Catholic Church, followed by the Ukrainian Greek Catholic Church.

With the exception of the Maronite Church, the Eastern Catholic Churches are groups that, at different points in the past, used to belong to the Eastern Orthodox Church, the Oriental Orthodox churches, or the Church of the East; these churches underwent various schisms through history. Eastern Catholic Churches that were formerly part of other communions have been points of controversy in ecumenical relations with the Eastern Orthodox and other non-Catholic churches. The five historic liturgical traditions of Eastern Christianity, namely the Alexandrian Rite, the Armenian Rite, the Byzantine Rite, the East Syriac Rite, and the West Syriac Rite, are all represented within Eastern Catholic liturgy. On occasion, this leads to a conflation of the liturgical word "rite" and the institutional word "church". Some Eastern Catholic jurisdictions admit members of churches not in communion with Rome to the Eucharist and the other sacraments.

The Syriac Orthodox Church (Classical Syriac: ܥܺܕܬܳܐ ܣܽܘܪܝܳܝܬܳܐ ܬܪܺܝܨܰܬ݂ ܫܽܘܒܚܳܐ, romanized: ʿIdto Sūryoyto Trīṣāth Šubḥō), also informally known as the Jacobite Church, is an Oriental Orthodox denomination that originated from the Church of Antioch. The Church currently has around 1.5 million followers worldwide. The Church upholds the Miaphysite doctrine in Christology and employs the Liturgy of Saint James, associated with James the Just. Classical Syriac is the official and liturgical language of the Church.

The supreme head of the Syriac Orthodox Church is the patriarch of Antioch, a bishop who, according to sacred tradition, continues the leadership passed down from Saint Peter. Since 2014, Ignatius Aphrem II has served as the Syriac Orthodox Antiochian patriarch. The Great Church of Antioch was the patriarchal seat and the headquarters of the Church until c. 518, after which Severus of Antioch had to flee to Alexandria, Egypt. After the death of Severus, the patriarchal seat moved from Egypt to different monasteries like the Mor Bar Sauma Monastery; some patriarchs also set up headquarters in Antioch temporarily. Later, Mor Hananyo Monastery was declared as the patriarchal seat and the headquarters of the Church from c. 1160 until 1932. In 1959, the patriarchal seat and headquarters were relocated to the Cathedral of Saint George in Bab Tuma, Damascus, Syria, due to conflicts in the region.

The Patriarch of Antioch is a traditional title held by the bishop of Antioch (modern-day Antakya, Turkey). As the traditional "overseer" (ἐπίσκοπος, episkopos, from which the word bishop is derived) of the first gentile Christian community, the position has been of prime importance in Pauline Christianity from its earliest period. This diocese is one of the few for which the names of its bishops from the apostolic beginnings have been preserved. Today five churches use the title of patriarch of Antioch: one Eastern Orthodox (the Greek Orthodox Church of Antioch); one Oriental Orthodox (the Syriac Orthodox Church); and three Eastern Catholic (the Maronite, Syriac Catholic, and Melkite Greek Catholic Churches).

According to the pre-congregation church tradition, this ancient patriarchate was founded by the Apostle Saint Peter. The patriarchal succession was disputed at the time of the Meletian schism in 362 and again after the Council of Chalcedon in 451, when there were rival Melkite and non-Chalcedonian claimants to the see. Following a 7th-century succession dispute in the Melkite Church, the Maronites also began appointing a Maronite patriarch. After the First Crusade, the Catholic Church began appointing a Latin Church patriarch of Antioch, though this became strictly titular after the Fall of Antioch in 1268, and was abolished completely in 1964. In the 18th century, succession disputes in the Greek Orthodox and Syriac Orthodox Churches of Antioch led to factions of those churches entering into communion with Rome under claimants to the patriarchate: respectively the Melkite Greek Catholic patriarch of Antioch and the Syriac Catholic patriarch of Antioch. Their respective Orthodox progenitors are the Greek Orthodox patriarch of Antioch and the Syriac Orthodox patriarch of Antioch.
