The Malankara Orthodox Syrian Church (MOSC) also known as the Indian Orthodox Church (IOC)[10] or simply as the Malankara Church, is an autocephalous Oriental Orthodox church headquartered in Devalokam, near Kottayam, India. The church serves India's Saint Thomas Christian (also known as Nasrani) population. According to tradition, these communities originated in the missions of Thomas the Apostle in the 1st century (circa 52 AD).[14] It employs the Malankara Rite, an Indian form of the West Syriac liturgical rite.
The MOSC descends from the Malankara Church and its affiliation with the Syriac Orthodox Church. However, between 1909 and 1912, a schism over the authority of the Syriac Orthodox Patriarch of Antioch's authority resulted in the dissolution of the unified Malankara Church and establishment of the overlapping and conflicting MOSC and Jacobite Syrian Christian Church (JSCC).
Since 1912, the MOSC has maintained a catholicate, the Catholicos of the East and Malankara Metropolitan–presently Baselios Marthoma Mathews III–who is the primate of the church. The MOSC drafted and formally adopted a constitution in 1934, wherein the church formally declared the Malankara Metropolitan and the Catholicos of the East as one. The Malankara Orthodox Syrian Church asserts communion with the other Oriental Orthodox churches. However, regular legal and occasional physical confrontations between the MOSC and the Syriac Orthodox JSCC have continued despite multiple efforts to reconcile the churches.

The Malankara Orthodox Syrian Church accepts miaphysitism, which holds that in the one person of Jesus Christ, divinity and humanity are united in one (μία, mia) nature (φύσις – "physis") without separation, without confusion, without alteration and without mixing[18] where Christ is consubstantial with God the Father. Around 500 bishops within the Patriarchates of Alexandria, Antioch and Jerusalem refused to accept the dyophysitism (two natures) doctrine decreed by the 4th ecumenical council, the Council of Chalcedon in 451,[dubious – discuss] an incident that resulted in the first major split in the main body of the Christian Church. While the Oriental Orthodox churches rejected the Chalcedonian definition, the sees that would later become the Catholic Church and the Eastern Orthodox Church accepted this council.
Self-reporting roughly 2.5 million members (with external estimates of roughly 1 million) across 30 dioceses worldwide, a significant proportion of the Malankara Orthodox Syrian Church's adherents reside in the southern India state of Kerala.

Chronological diagram of Saint Thomas Christian denominations


According to tradition, Christianity first arrived in India with Thomas the Apostle during the 1st century AD, evolving into Saint Thomas Christianity over several centuries. While isolated and generally independent in administration, Indian Christians maintained contact with the Christian hierarchies of Antioch, Persia, and potentially Alexandria. The Saint Thomas Christians had relationships with the Persian Church of the East from at least the 6th century onward. The Indians inherited its East Syriac dialect for liturgical use and gradually became Syriac Christians in ritual and doctrine. They received clerical support from Persian bishops, who traveled to Kerala in merchant ships on the spice route. For much of this period, Saint Thomas Christians were under the leadership of an archdeacon (a native ecclesiastical head with temporal powers, deriving from the Greek arkhidiākonos).
During the 16th century, efforts by the Portuguese Padroado–an arm of the Catholic Church–to bring the Saint Thomas Christians under the administration of the Latin Church and attempts to Latinize the Malankara Rite led to the first of several rifts in the community. These divisions intensified following the 1599 Synod of Diamper. Saint Thomas Christians who were opposed to the Portuguese Padroado missionaries took the Coonan Cross Oath on 3 January 1653. The Dutch East India Company expolusion of the Portuguese from much of Malabar enabled the reconciliation of some Saint Thomas Christians and the Catholic Church, with this group eventually evolving into the Syro-Malabar Catholic Church, an Eastern Catholic church that adopted the Chaldean Catholic Church's East Syriac Rite and Diophysite christology.

Malankara Church

Many Saint Thomas Christian chose to remain independent from the Catholic Church. Patriarch Gregorios Abdal Jaleel, the Syriac Orthodox Archbishop of Jerusalem, witnessed the 1665 ordination of Thomas as Bishop Thoma I, who forged a renewed relationship with the Syriac Orthodox Church of Antioch and Saint Thomas Christians, which laid the foundation for adopting West Syrian liturgy and practices over the next two centuries. Those who supported the indigenous church leader of Malankara, Thoma I, and adopted West Syrian liturgies and practices and Miaphysite faith evolved into the Malankara Church.

19th century
The Arthat Padiyola declared that the administration of Malankara Church was independent and the bishops from Rome, Antioch, and Babylon had no role in the Malankara Church hierarchy, despite continued efforts to integrate the remaining independent Saint Thomas Christians into these patriarchates. In 1807, four gospels of Holy Bible in Syriac were translated to Malayalam by Kayamkulam Philipose Ramban. The Malankara Orthodox Theological Seminary in Kottayam was established in 1815 under the leadership of Pulikottil Ittup Ramban (Mar Dionysius II). The Mavelikara Synod (Padiyola) led by Cheppad Mar Dionysius rejected the suggestions put forward by Anglican missioneries and Reformation group and declared the beliefs and theology of Malankara Church were same as the Syriac Orthodox Church of Antioch.

20th century
Geevarghese Dionysius of Vattasseril, who became the Malankara metropolitan bishop in 1908, played a significant role with the other clerical and lay leaders of Malankara in re-establishing the Catholicos of the East in India in 1912. In 1909 the relations with the Syrian Orthodox Church soured, when Patriarch Ignatius Abded Aloho II who arrived in India, began demanding registered deeds granting the patriarch temporal authority over the church. Dionysius rejected the request and thus emerged two factions in the church. The faction that supported the Patriarch came to be called as "Bava Kakshi" ( Patriarch Faction) and faction that supported the Malankara Metropolitan came to be known as "Methran Kakshi" (Metropolitan Faction). The Malankara Orthodox Syrian Church wanted to retain its autocephaly, and appealed to Syriac Orthodox Patriarch of Antioch Ignatius Abdul Masih II. He enthroned Murimattathil Paulose Ivanios as Baselios Paulose I, Catholicos of the East, on the apostolic throne of St. Thomas at St. Mary's Church in Niranam on 15 September 1912.
In 1934, The Malankara Church adopted a constitution for smooth functioning of the church, parishes and institution. In 1947, Saint Gregorios of Parumala was declared as a saint by the Church. In 1952 the Official Residence of the Malankara Metropolitan and the Headquarters of Malankara Church was shifted to Devalokam from Pazhaya Seminary. In 1958, The Supreme Court declared Catholicos Baselios Geevarghese II as the legitimate Malankara Metropolitan. The two factions of the Malankara Orthodox Church rejoined. In 1964, Syriac Orthodox Patriarch of Antioch participated in the enthronement ceremony of the Catholicos and Malankara Metropolitan, Baselios Augen I. In 1995, the Supreme Court of India declared the MOSC constitution adopted in 1934 was valid.

21st century
In 2002, fresh elections were conducted in Malankara Association under the observation of Supreme Court of India. The Supreme Court declared Catholicos Baselios Mathews II is the official and legitimate Malankara Metropolitan and also declared that this decision cannot be disputed in any platform. In 2003, Vattasheril Dionysius VI was declared as a saint. In 2012, the centennial of the establishment of the church and Catholicate were celebrated with history classes and church publications. On 3 July 2017, a major verdict by the Supreme Court of India declared the MOSC legally applicable to all parishes in disputed possession between the MOSC and Jacobite Syrian Christian Church.

Hierarchy, presence and doctrine
The spiritual head of the church is the Catholicos of the East, and its temporal head is the Malankara Metropolitan. Since 1934, both titles have been vested in one person; the official title of the head of the church is "The Catholicos of the Apostolic Throne of Saint Thomas and The Malankara Metropolitan". Baselios Marthoma Paulose II was enthroned as the Malankara Metropolitan and the Catholicos of the Malankara Church on 1 November 2010 at St. Peter and St. Paul's Church, Parumala. He is the eighth Catholicose of the East in Malankara and the 21st Malankara Metropolitan.
Oriental Orthodox Churches, including the Malankara Orthodox Syrian Church, accept only the first three ecumenical councils: the First Council of Nicaea, the First Council of Constantinople, and the Council of Ephesus. The church, like all other Oriental Orthodox Churches, uses the original Nicene Creed without the filioque clause. Like the Syriac Orthodox Church, it primarily uses the liturgy of Saint James in Malayalam, Konkani, Kannada, Hindi, English and other Indian languages.

Liturgy and canonical hours
The church has used the Malankara Rite, part of the Antiochene Rite, since the 17th century. The Jacobite Church and the Maronite Church also belong to the same liturgical family. In the first half of the fifth century, the Antiochene church adopted the Liturgy of Saint James. In the 4th and 5th centuries, The liturgical language of fourth- and fifth-century Jerusalem and Antioch was Greek, and the original liturgy was composed in Greek.
After the Council of Chalcedon in 451, the Eastern Church was divided in two; one group accepted the council, and the other opposed it. Both groups continued to use the Greek version of the Saint James liturgy. The Byzantine emperor Justin (518–527) expelled the opponents from Antioch, and they took refugees in the Syriac-speaking Mesopotamia on the Roman–Persian border (modern eastern Syria, Iraq, and southeastern Turkey). The Antiochene liturgical rites were gradually translated into Syriac, and Syriac hymns were introduced.
Gregorios Abdal Jaleel came to Malankara from Jerusalem in 1665 and introduced Syriac Orthodox liturgical rites. The most striking characteristic of the Antiochene liturgy is its large number of anaphoras (celebrations of the Eucharist). About eighty are known, and about a dozen are used in India. All have been composed following the Liturgy of Saint James.
Christians of the Malankara Orthodox Syrian Church pray the canonical hours of the Shehimo at fixed prayer times seven times a day.
