West Syriac Rite in the context of "Eastern Catholic Churches"

Maronite Cypriots are an ethnoreligious group and are members of the Maronite Catholic Archeparchy of Cyprus whose ancestors migrated from the Levant during the Middle Ages. A percentage of them traditionally speak a variety of Arabic known as Cypriot Arabic, in addition to Greek. People speaking this Arabic dialect originate from one village, specifically Kormakitis. As Eastern Catholics of the West Syriac Rite, they are in full communion with the Catholic Church of Rome.

As of 2025 the Archbishop of Cyprus was Selim Jean Sfeir, born in Rayfoun, Lebanon on 2 September 1958. He was ordained Archbishop on 19 June 2021. He succeeded Joseph Soueif, who had been installed as the Archbishop of Tripoli, Lebanon in 2020.

The Liturgy of Saint James is a form of Christian liturgy used by some Eastern Christians of the Byzantine rite and West Syriac Rite. It is developed from an ancient Egyptian form of the Basilean anaphoric family, and is influenced by the traditions of the rite of the Church of Jerusalem, as the Mystagogic Catecheses of Cyril of Jerusalem imply. It became the primary Divine Liturgy in the Church of Antioch and Church of Jerusalem in the early fifth century, soon becoming supplanted by the liturgies of Saint Basil and Saint John Chrysostom. It is still the principal liturgy of the Syriac Orthodox Church, the Malankara Orthodox Syrian Church, the Maronite Church, the Syriac Catholic Church, Syro-Malankara Catholic Church and other churches employing the West Syriac Rite. It is also occasionally used in the Eastern Orthodox Church and Melkite Catholic Church. The Malankara Mar Thoma Syrian Church uses a reformed variant of this liturgy, omitting intercession of saints and prayer for the dead.

The liturgy is attributed with the name of James the Just and patriarch among the Jewish Christians at Jerusalem.

The Malankara Mar Thoma Syrian Church, often shortened to Mar Thoma Church, and known also as the Reformed Syrian Church and the Mar Thoma Syrian Church of Malabar, is an autonomous Oriental Protestant Christian church based in Kerala, India. While continuing many of the Syriac high church practices, the church is Protestant in its theology and doctrines. It employs a reformed variant of the West Syriac Rite Divine Liturgy of Saint James, translated to Malayalam.

The Mar Thoma Church sees itself as continuation of the Saint Thomas Christians, a community traditionally believed to have been founded in the first century by Thomas the Apostle, who is known as Mar Thoma (Saint Thomas) in Syriac, and describes itself as "Apostolic in origin, Universal in nature, Biblical in faith, Evangelical in principle, Ecumenical in outlook, Oriental in worship, Democratic in function, and Episcopal in character".

The East Syriac Rite, or East Syrian Rite (also called the Edessan Rite, Assyrian Rite, Persian Rite, Chaldean Rite, Nestorian Rite, Babylonian Rite or Syro-Oriental Rite), is an Eastern Christian liturgical rite that employs the Divine Liturgy of Saints Addai and Mari and utilizes the East Syriac dialect as its liturgical language. It is one of the two main liturgical rites of Syriac Christianity, along with the West Syriac Rite (Syro-Antiochene Rite).

The East Syriac Rite originated in Edessa, Mesopotamia, and was historically used in the Church of the East—the largest branch of Christianity operating primarily east of the Roman Empire—, with pockets of adherents as far as South India, Central and Inner Asia, and a strong presence in the Sasanian (Persian) Empire. The Church of the East traces its origins to the 1st century, when Saint Thomas the Apostle and his disciples Saint Addai and Saint Mari brought the faith to ancient Mesopotamia (today's modern Iraq, eastern Syria, southeastern Turkey, and regions along the Turkish–Syrian and Iran–Iraq borders). According to traditional accounts, Thomas the Apostle is believed to have traveled as far as the Malabar coast of southwestern India. This account is not yet confirmed, as the earliest-record for an organised Christian presence in India is from the 6th century account of Alexandrian traveller Cosmas Indicopleustes.

The Saint Thomas Christians, also called Syrian Christians of India, Marthoma Suriyani Nasrani, Malankara Nasrani, or Nasrani Mappila, are an ethno-religious community of Indian Christians in the state of Kerala (Malabar region), who, for the most part, employ the Eastern and Western liturgical rites of Syriac Christianity. They trace their origins to the evangelistic activity of Thomas the Apostle in the 1st century. The Saint Thomas Christians had been historically a part of the hierarchy of the Church of the East but are now divided into several different Eastern Catholic, Oriental Orthodox, Protestant, and independent bodies, each with their own liturgies and traditions. They are based in Kerala and they speak Malayalam. Nasrani or Nazarene is a Syriac term for Christians, who were among the first converts to Christianity in the Near East.

Historically, this community was organised as the Province of India of the Church of the East, by Patriarch Timothy I (780–823 AD) in the eighth century, it was served by bishops and a local dynastic archdeacon. In the 14th century, the Church of the East declined in the Near East, due to persecution from Tamerlane. Portuguese colonial overtures to bring St Thomas Christians into the Latin Church of the Catholic Church, administered by their Padroado system in the 16th century, led to the first of several rifts (schisms) in the community. The attempts of the Portuguese culminated in the Synod of Diamper, formally subjugating them to the Portuguese Padroado and imposing upon them the Roman Rite of worship. The Portuguese oppression provoked a violent resistance among the Thomasine Christians, that took expression in the Coonan Cross Oath protest in 1653. This led to the permanent schism among the Thomas' Christians of India, leading to the formation of Puthankoor or Puthankūttukār ("New allegiance" ) and Paḻayakūṟ or Pazhayakūr ("Old allegiance") factions. The Paḻayakūṟ comprise the present day Syro-Malabar Church and Chaldean Syrian Church which continue to employ the original East Syriac Rite. The Puthankoottukar, who continued to resist the Catholic missionaries, organized themselves as the independent Malankara Church and entered into a new communion with the Syriac Orthodox Church of Antioch, inheriting from them the West Syriac Rite, replacing the old East Syriac Rite liturgy.

A use, also commonly usage (Latin: usum) and recension, within Christian liturgy is a set of particular texts or customs distinct from other practitioners of a broader liturgical ritual family, typically on the basis of locality or religious order. Especially prevalent within the Latin liturgical rites of the Middle Ages, few significant uses persisted following a general suppression of these variations by Pope Pius V in the 16th century. The word "use" is most commonly applied to distinct practices branching from the Roman Rite, though it and "recension" can be applied in variations of other ritual families, such as the Ruthenian recension of the Byzantine Rite, the Maronite Use of the West Syriac Rite and the Syro-Malabar Use of the East Syriac Rite. In the historic context of the Scottish Episcopal Church, "usage" refers to certain aspects of the Eucharistic liturgy valued by some nonjurors.
