The term "Melkite" , also written "Melchite", refers to various Byzantine Rite Christian churches and their members originating in the Middle East. The word comes from the Syriac word malkoyo , and the Arabic word Malakī (, meaning "royal", and by extension, "imperial"). When used in an ecclesiastical sense, it refers specifically to the Melkite Greek Catholic Church as an ethnoreligious group.
Melkites view themselves as the first Christian community, dating the Melkite Church back to the time of the Apostles. This first community is said to have been a mixed one made up of individuals who were originally Greek, Greco- Macedonian, Roman, Syriac, and Jewish.
Hellenistic Judaism and the Judeo-Greek "wisdom" literature popular in the late Second Temple era amongst both Hellenized Jews (known as Mityavnim) and gentile Greek proselyte converts to Judaism played an important part in the formation of the Melkite tradition.
After the Islamic conquests of the Levant in the 7th century, the Melkite community started incorporating Arabic language in the liturgical traditions as the Middle East became gradually Arabized. The term Melkite was originally used as a pejorative term after the acrimonious division that occurred in Eastern Christianity after the Council of Chalcedon (451). It was used by non-Chalcedonians to refer to those who backed the council and the Byzantine Emperor (malko and its cognates are Semitic words for "king"). "It was only towards the end of the fifth century that it took the name of Melkite". The Melkites were generally Greek-speaking city-dwellers living in the west of the Levant and in Egypt, as opposed to the more provincial Syriac- and Coptic-speaking non-Chalcedonians. The Melkite Church was organised into three historic patriarchates — Alexandria, Antioch and Jerusalem — in union with the Patriarch of Constantinople. After the Council of Chalcedon, over the ensuing centuries those Churches which rejected this council recognised different patriarchs in Alexandria ( Coptic Orthodox Church) and Antioch ( Syriac Orthodox Church). The Nubian kingdom of Makuria (in modern Sudan) in contrast to their Non-Chalcedonian Ethiopian Orthodox neighbours, was also Chalcedonian, from c. 575 until c. 710 and still had a large Melkite minority until the 15th century.
From 1342, Roman Catholic clergy were based in Damascus and other areas, and worked toward a union between Rome and the Orthodox. At that time, the nature of the East-West Schism, normally dated to 1054, was undefined, and many of those who continued to worship and work within the Melkite Church became identified as a pro-Western party. In 1724, Cyril VI (Seraphim Tanas) was elected in Damascus by the Synod as Patriarch of Antioch. Considering this to be a Catholic takeover attempt, Jeremias III of Constantinople imposed a deacon, the Greek monk Sylvester to rule the patriarchate instead of Cyril. After being ordained a priest, then bishop he was given Turkish protection to overthrow Cyril. Sylvester's heavy-handed leadership of the church encouraged many to re-examine the validity of Cyril's claim to the patriarchal throne.
The newly elected Pope Benedict XIII (1724–1730) also recognised the legitimacy of Cyril's claim and recognized him and his followers as being in communion with Rome. From that point onwards, the Melkite Church was divided between the Greek Orthodox ( Greek Orthodox Church of Antioch), who continued to be appointed by the authority of the Patriarch of Constantinople until the late 19th century, and the Greek Catholics ( Melkite Greek Catholic Church), who recognize the authority of the Pope of Rome. However, it is now only the Catholic group who continue to use the title Melkite; thus, in modern usage, the term applies almost exclusively to the Arabic-speaking Greek Catholics from the Middle East.
Some typically Grecian "Ancient Synagogal" priestly rites and hymns have survived partially to the present, notably in the distinct church services of the Melkite and Greek Orthodox communities of the Hatay Province of Southern Turkey, Syria and Lebanon. Members of theses communities still call themselves Rûm which literally means "Roman" or "Asian Greek" in Arabic (that is, those of the (Eastern) Roman Empire, what English speakers often call "Byzantine"). The term "Rûm" is used in preference to "Ionani" or "Yāvāni" which means "European-Greek" or Ionian in Classical Arabic and Biblical Hebrew.
