Mar Gregorios believed that the church should engage in educational activity especially to facilitate primary education and English teaching without discriminating gender or religion. Accordingly he started schools at Kunnamkulam, Mulamthuruthy, Niranam, Thumpamon, Thiruvalla etc. The missionary task of the Church was also evinced by his outreach programme to the socially down trodden communities at Chennithala, Kalikunnu, Mallappally, Puthupally, Kallumkathara etc. He also organized evangelical awakening programme for non-Christians at various places like Aluva, under the leadership of the Seminary students.
A major task of Mar Gregorios was to motivate the clergy for effective ministry. With this aim, he formed the Malankara Syrian Clergy Association and took many progressive decisions and made many suggestions for the effective functioning of the priestly ministry.
