Catholicate of the East The Malankara Orthodox Syrian Church was founded by one of the twelve apostles of Jesus Christ, St. Thomas, who came to India in A.D. 52. At least from the fourth century, the Indian Church entered into a close relationship with the Persian or East Syrian Church. From the Persians, the Indians inherited The East Syrian language and liturgies, and gradually came to be known as Syrian Christians. In the seventeenth century, the Church came into relationship with the Antiochene Church, which again caused splits. As a result of this relationship, the Church received West Syrian liturgies and practices. The Church entered into a new phase of its history by the establishment of the Catholicate in 1912.
The Church is in communion with the other Oriental Orthodox Churches namely, Syriac, Alexandrian, Armenian, Eritrean and Ethiopian Orthodox Churches. The Church is in good ecumenical relationship with the Eastern Orthodox, Roman Catholic and Protestant Churches.
