Holy See of St.Thomas

The Malankara Orthodox Syriac Church, which is the Holy See of the East, is the See of St. Thomas, the Apostle; and its head, the Catholicos is the legitimate successor of St. Thomas. The Catholicate of the East was established at the Jerusalem Synod in 231 A.D. The headquarters of the Church was first in Edessa in Persia. This was moved to Selucia, then to Tigris and Musal. It was transferred and restored in Malankara, India in 1912. The present headquarters is at Devalokam, Kottayam, Kerala, India.  His Holiness Mor Thoma Baselius Didymos I is the current head of the Orthodox Syriac Church of East and he is the 90th successor of St. Thomas on his Apostolic Throne.
