Pazhayakoottukar
The Paḻayakūṟ (Pazhayakoor; Malayalam: പഴയകൂർ; English: "Old Allegiance"), also known as Romo-Syrians or Syrian Catholics of Malabar, are the Saint Thomas Christians who use the East Syriac Rite and claim apostolic origin from the Indian mission of Thomas the Apostle in the 1st century AD. The Saint Thomas Christians were originally in full communion with the Church of the East in Persia, from whom they inherited the East Syriac liturgical rite. Through the Schism of 1552, a faction of the Church of the East entered the Catholic Church.
