Dr. Richards says of him with just pride that he was “the Wyclif of the Syrian Church in Malabar.”…The Reformers calls themselves the “Mar Thomas Christians”. They are considerably Protestantized. They have no images, denounce the idea of the Eucharistic sacrifice, pray neither to the saints nor for the dead, and use the vernacular (Malayalam) for their services…If only we knew what the views of the Church of England in matters of faith are, it would be easier to estimate those of the Mar Thomas Christians.»

ISBN978-1-5246-7652-0. «Metropolitan Juhanon Mar Thoma called it "a Protestant Church in an oriental grab."...As a reformed Oriental Church, it agrees with the reformed doctrines of the Western Churches. Therefore, there is much in common in faith and doctrine between the MTC and the reformed Churches of the West. As the Church now sees it, just as the Anglican Church is a Western Reformed Church, the MTC is an Eastern Reformed Church. At the same time as it continues in the apostolic episcopal tradition and ancient oriental practices, it has much in common with the Oriental Orthodox Churches. Thus, it is regarded as a "bridging Church".»
