The Malankara Orthodox Syrian Church is an ancient Christian denomination based in India, primarily in the state of Kerala. It traces its roots to the arrival of St. Thomas the Apostle in the 1st century AD, who is believed to have established Christianity in the region. The church is part of the larger Oriental Orthodox communion and follows the West Syrian liturgical tradition. The church emphasizes the importance of the sacraments, particularly the Eucharist, and maintains a rich tradition of worship and spirituality. It is governed by a hierarchy of bishops, with the Catholicos of the East serving as its spiritual leader. The Malankara Orthodox Syrian Church also engages in various social and educational initiatives to serve its community.
