MGOCSM & OCYM
Mar Gregorios Orthodox Christian Student Movement (MGOCSM) is the student wing of the Malankara Orthodox Syrian Church. The 
students and senior leaders of our church who were residing in Madras (Chennai), India in the early part of this century felt the need for an organization to bring together our students in various colleges and high schools with a view to deepening their spiritual life and to create in them a livelier sense of fellowship. So they founded the Syrian Student Conference in 1907 and first conference was convened on January 1st, 1908 at Tiruvalla, Kerala, India. Annual conferences have been a regular feature since that year. The Syrian student conference, the parent organization, assumed its present name MGOCSM in 1960. it is the oldest Christian student organization in India. its motto is Worship – Service – Study.
MGOCSM have been maintaining inter-disciplinary contacts in the academic field for along time by the formation of its wings.
