The Malankara Orthodox Syrian Church is popularly known as Indian Orthodox Church in the International Orthodox Communion of Churches. This Church is believed to have been founded by the Apostle Thomas in his mission to India and the Eastern regions of the Roman Empire in the first century AD. This Indian Orthodox Church was known as Jacobite Church from 1665, until the adoption of new constitution of the church in 1934. This change was made in confirmation with its theological and traditional connections with other Orthodox church bodies of the world.
