The Jacobite Syrian Christian Church, also known as the Malankara Syriac Orthodox Church, Malankara Jacobite Syrian Church, Malankara Jacobite Syriac Orthodox Church, or the Syriac Orthodox Church in India, is an autonomous maphrianate of the Syriac Orthodox Church of Antioch based in Kerala, India. It is headed by the catholicos of India, Mor Baselios Joseph.
According to tradition, the community traces its origin to Thomas the Apostle's mission to South India in AD 52. Over time, it became an integral part of Syriac Christendom, utilizing East Syriac liturgical practices and relying on visiting bishops for spiritual guidance, while a native archdeacon oversaw temporal affairs.
In the 16th century Portuguese missionaries enforced Latin Catholic jurisdiction, severing the Malankara Church's links to the Syriac Church and enforcing Latinized liturgical customs. Following the Council of Diamper, the community rejected Latinization through the Coonan Cross oath and re-established contact with Syriac Christians.
In subsequent centuries, the Malankara metropolitans were consecrated by delegates sent by the Syriac Antiochian patriarch, who guided the community in de-Latinizing and adopting West Syriac liturgical traditions, theology, and canonical governance. The 20th century saw the revival of the historical maphrianate, governed by the catholicos of India alongside a regional holy synod.
Headquartered at the patriarchal centre in Puthencruz, Kerala, it serves a global population of around 1 million people, through various dioceses and patriarchal vicariates in India and around the world. The church employs the West Syriac Rite, with the principal Eucharistic liturgy being the Liturgy of James the Just. Classical Syriac served as the historical language of worship, but translations throughout the 19th and 20th centuries led to the widespread adoption of Malayalam and other local languages.
Name In the aftermath of the Council of Chalcedon, which fractured the Christian Church, Emperor Justin I, who supported the council, exiled Patriarch Severus of Antioch to Egypt, for refusing to accept the council, and professing Miaphysite Christology. The Syriac Orthodox Church is the church of Antioch that continued to accept Severus as patriarch until his death in 538 AD. During this turbulent time for the church, Jacob Baradaeus was consecrated as bishop with the support of Empress Theodora and he led and revived the church. The term "Jacobite" was originally used as a derogatory word for Miaphysites from the church of Antioch.
In the aftermath of the Coonan Cross oath (1653), the Portuguese Padroado missionaries began using the term "Jacobites" to designate the indigenous Christians who were a part of the Syriac Orthodox Church under Patriarch Ignatius Abdulmasih I and Metropolitan Thoma I. Throughout the 18th and 19th centuries, members of the community were frequently referred to in colonial records and historical texts as "Jacobite Syrians," though the indigenous ecclesiastical body was officially known as the "Malankara Church." Following the 1889 reformist schism, the orthodox faction formally adopted the title "Malankara Jacobite Syrian Church" to distinguish its traditionalist identity. In 2002, the historic Puthencruz convention officially adopted the contemporary legal title "Jacobite Syrian Christian Church" in its constitutional framework.
The geographical designation "Malankara" derives from Maliankara, a coastal locality near Kodungallur where, according to local tradition, Thomas the Apostle landed in 52 AD and established one of his first churches in India. The designation "Syrian" reflects the church's Syriac heritage—an ancient Semitic Christian tradition that uses Classical Syriac, an Edessan dialect of Aramaic (the language traditionally believed to be spoken by Christ) as a sacred liturgical language—rather than a political affiliation with the modern nation-state of Syria. To prevent ongoing secular misinterpretation between the state of Syria and the Syriac heritage, the holy synod of the Syriac Orthodox Church officially adopted the English title "Syriac Orthodox Church" in 2000. However, many older churches and institutions continue to use the name "Syrian".
The term "Orthodox" derives from the Greek for "right belief," reflecting the Oriental Orthodox communion's maintenance of the apostolic faith as upheld by the ecumenical councils at Nicaea (325 AD), Constantinople (381 AD), and Ephesus (431 AD). Historically, the community has referred to itself in the local Malayalam vernacular as Sathya Suryani Sabha (സത്യ സുറിയാനി സഭ), which means "Syriac Orthodox Church," with "Sathya" being translated as "True" or "Orthodox". Additionally, some historians and linguists propose that the name Tharissa Palli—the church referenced in the 9th-century Quilon copper plates—derives from the Syriac root Trishath, meaning "upright", "true", or "orthodox".
History
Apostolic origins and early history (1st–3rd Centuries) The origin of the Malankara Church is traditionally attributed to the evangelism of Thomas the Apostle, who according to community tradition arrived at the port of Muziris (near present-day Kodungallur, Kerala) in 52 AD. Church tradition holds that St. Thomas established seven and a half churches along the Malabar Coast and ordained clergy before his martyrdom at Mylapore in 72 AD.
Historians note that early Christian communities along the Malabar Coast grew primarily along Indo-Roman and Persian maritime trade routes. Patristic writers such as Eusebius of Caesarea and St. Jerome record that Pantaenus, an Alexandrian Christian scholar, visited India around 190 AD and reported finding an established community of believers who preserved a Hebrew text of the Gospel of Matthew. During this era, indigenous believers were referred to as Nasranis (Saint Thomas Christians).
Syriac migrations and medieval expansion (4th–15th centuries) The indigenous Christian community faced a gradual decline, due to a lack of ecclessiastical structure, leaving the church vulnerable and spiritually weakened. In 345 AD, the demography and ecclesiastical structure of the Malabar church were transformed through the Knanaya migration led by the merchant St. Thomas of Cana, accompanied by a bishop, priests, and several dozen families from the Middle East. This event deepened liturgical, cultural, and administrative ties between South India and Syriac Christendom.
A second major migration occurred in the 9th century (823–825 AD), when a group of Persian merchants and clergy led by the merchant Marwan Sabrisho and two bishops, Mar Sapor and Mar Proth, arrived at the port of Kollam (Quilon). The local Venad ruler, Ayyanadikal Thiruvadikal, issued the 9th-century Quilon Syrian copper plates in 849 AD. These charters bestowed extensive civil, economic, tax-exempt, and judicial privileges upon the local Christian merchant guild and established Kollam as a major trade center. The arrival of this migration is closely associated in local tradition with the start of the Malayalam era (Kollavarsham) in 825 AD.
Throughout these centuries, the Nasranis maintained ongoing ties with the Syriac Church, operating under a dual organizational structure: local secular and civil administration was led by an archdeacon, which was a de facto hereditary role passed on through the Pakalomattom family, while spiritual hierarchy, sacraments, and liturgical traditions were sustained through ecclesiastical networks connected to the ancient sees of the east. Because they were ecclesiastically a part of the Syriac Church, they became known as Syriac Christians.
Between the 9th and 15th centuries, the Nasranis consolidated their position as an influential socio-economic and military power along the Malabar Coast. During this era, local traditions and European travel accounts record the existence of the Villarvattom Dynasty, a native Christian ruling house centered around Udayamperoor and Chendamangalam that held feudatory rights under the Second Chera Kingdom and later the Kingdom of Cochin. Operating as dominant merchant guilds they controlled major maritime trade routes, collected customs duties, and managed key port infrastructures alongside local rulers. This economic prominence earned the community high socio-feudal status, equivalent to the Nair military nobility. Local Hindu monarchs granted them hereditary honors, including the rights to carry arms, ride elephants, and use ceremonial processional insignia.
Culturally, this period saw the emergence of Karshoni—a dialect of Malayalam that was written using the Syriac alphabet—which scribes used to transcribe liturgical texts, administrative records, and prayer books, preserving native linguistic forms before the standardization of the Brahmic Malayalam script.
Western colonization and latinization (16th–17th centuries) The arrival of Vasco da Gama in 1498 introduced European colonial power dynamics to the Malabar Coast. Portuguese missionaries sought to integrate the indigenous Nasranis into the Latin rite of the Roman Catholic Church under the padroado system. This policy culminated in the Synod of Diamper in June 1599, convened by Archbishop Aleixo de Menezes of Goa. The synod severed the Malankara Church's links to the Syriac Church and enforced latinized liturgical customs.
Resistance to Portuguese latinization led to the Coonan Cross oath on January 3, 1653, at Mattancherry, where the majority of Nasranis swore a collective oath to break free from Portuguese Jesuit authority. Following the revolt, the assembly elevated Archdeacon Thomas to episcopal status as Mar Thoma I, inaugurating the office of the metropolitan of Malankara as the ecclesiastical and temporal leader of the community. The faction that accepted Catholicism evolved into the Syro-Malabar Catholic Church.
To formalize and regularize his episcopal consecration according to eastern canonical traditions, the Nasrani community made direct contact with the Patriarchate of Antioch. In 1665, Mor Gregorios Abdal Jaleel, the metropolitan of Jerusalem sent by Patriarch Ignatius Abdulmasih I, arrived in Malabar. He regularized Mar Thoma I’s episcopacy and affirmed administrative ties with the Patriarchate of Antioch, strengthening the community's adherence to Oriental Orthodox theology, and West Syriac liturgical practices.
Malankara metropolitanate and missionary relations (1685–1875)
Following the 1665 delegation, successive hierarchs delegated by the patriarchs of Antioch visited Malabar
to assist in church governance, codify liturgical traditions, and protect the community from foreign colonial influences. In 1685, a delegation led by Maphrian Mor Baselios Yeldho arrived in Kerala with Hidatyullah Ramban (later Mor Ivanios Hidatyullah) at the request of Mar Thoma II. Mor Baselios Yeldho passed away shortly after arrival at Kothamangalam, where his tomb at Marthoman Church remains a major center of pilgrimage. Mor Ivanios remained in Kerala to systematically teach theology, liturgical music, and canonical practices.
