The catechetical heritage of the Syro-Malabar Church is as old as this Church itself. As was the case with all other Churches, among the St. Thomas Christians also there existed a system of catechesis by which faith was handed down from generation to generation. However there is no comprehensive and chronological exposition of the history of catechesis of the Syro-Malabar Church. Hence, many things have to be traced from the historical documents and living traditions of the Church.
