Catholicos is a title used by Eastern and Oriental Orthodox Churches to denote the head of a Church or a dignitary of the highest order. There are two perspectives from each of two churches. One is that of the Malankara Orthodox Syrian Church (Indian Orthodox Church). The other represents the viewpoint of the Syriac Orthodox Church and its local body, the Malankara Jacobite Syrian Orthodox Church. Each of these primates administer approximately 2 million faithful. The Syriac Orthodox Church, including the Indian Orthodox Church, includes perhaps 2.5 million members worldwide.
