The formal origin of the Mar Thoma Sunday School was in the year 1905. But before 1905, there were few churches who had Sunday Schools in their respective parishes in Kerala. An example would be the Church at Kandanad, where 50 elders gathered together and took a decision to promote Christian education to their children, uncompromisingly. Our forefathers and mothers realized this as a glaring need and began to engage the children by teaching them the life of Jesus Christ. Some of the English missionaries like Thomas Walker and Wordsworth inspired and energized people to promote this cause.

An advisory meeting was convened on 25 February, 1905, Saturday evening at the Maramon Convention tent (pandal) according to prior notice. The meeting was chaired by Rev. C.P Philipose. The main decision taken there was to bring all the different Sunday Schools functioning in the Marthoma community churches as an institution by the name, Malankara Marthoma Syrian Christian Sunday School Samajam.
