The
Jacobite Syrian Christian Church, or the
Syriac Orthodox Church in India, is a Maphrianate of the Syriac Orthodox Church of Antioch based in Kerala, India and part of the Oriental Orthodox Church. It recognizes the Syriac Orthodox patriarch of Antioch and All the East as supreme head of the church. It functions autonomously within the church as an Archdiocese, administered by the Metropolitan Trustee, under the authority of the Maphrian of India, Baselios Thomas I. Following schism with the Malankara Orthodox Syrian Church, it is currently the only church in Malankara that is under the administrative supervision of Syriac Orthodox Church. The church employs the West Syriac Rite Liturgy of Saint James.
