The Orthodox Theological Seminary, also known as Old Seminary and M. D. Orthodox Seminary, is a seminary of the Malankara Orthodox Syrian Church. It was founded in 1815 by priest-monk Pulikkottil Joseph Ittoop Ramban with the help of Colonel John Munro to serve the Malankara Syrian Church and to invite CMS missionaries to teach theology. At that time, deacons were ordained as priests without an organized theological education. After the arrival of CMS missionaries, theological education was organized for the priests.
