The Syro-Malankara Catholic Church (also known as Malankara Syrian Catholic Church, Malankara Syriac Catholic Church) is an Eastern Catholic Church in full communion with the Holy See. The Church is one of the Saint Thomas Christian Churches centered in Kerala, India, which trace their origin to the evangelism of Saint Thomas the Apostle in the 1st century. Among the Eastern Catholic Churches, the Syro-Malankara Catholic Church is a major archepiscopal Church, headed by Major Archbishop and Catholicos Baselios Mar Cleemis, who was elected in 2007.
The liturgy of the Syro-Malankara Catholic Church is of the Antiochene rite, West Syrian in character. The liturgy today is celebrated in Malayalam, Syriac, English, Tamil, and Hindi.
The Church was established in 1930 when it split from the Malankara Orthodox Syrian Church, an Oriental Orthodox Church, and subsequently entered into communion with the Holy See. The Malankara Church itself had emerged out of the split within the Saint Thomas Christian community of the 16th century; previously the entire community had comprised a province of the Church of the East, or the Nestorian Church, based in Persia. However, the collapse of that Church and influence from the Portuguese, who tried to bring them under the Latin rite of the Catholic Church, led to a rift in the community. Eventually, the majority entered into communion with Rome as the Eastern Catholic Syro-Malabar Catholic Church, while the rest formed the Malankara Church and aligned with the Syrian Orthodox Church. Taking only five members of his church with him, Mar Ivanios had founded the Syro-Malankara Catholic Church, on Sept. 20, 1930. Pope Pius XI. through the Apostolic Constitution Christo Pastorum Principi of June 11, 1932, established the Syro-Malankara Hierarchy for the reunited community and erected the archiparchy of Trivandrum with the eparchy of Tiruvalla as its suffragan.The metropolitan eparchy of Trivandrum was established in 1932. Mar Ivanios was enthroned as its first metropolitan archbishop.
