The Diocese of Delhi was carved out of the outside Kerala Diocese of the Malankara Orthodox Syrian Church in the year 1975. The Diocese in the National Capital Region had been functioning as the backbone of the Church right from the time of its inception. The Diocese has been blessed in terms of the able leadership it has received time and again and the sincerity of its people, who living away from their homeland, have left no stone unturned in their pursuit of the growth of the Church in the regions where it was never been known.

The Diocese was first entrusted to the pioneering visionary and a world renowned scholar, the late lamented Dr. Paulos Mar Gregorios, of blessed memory, whose tireless and bold leadership was quintessential in leaving his imprint in the early stages of Church. The growth of the Church, especially in terms of the large number of parishes and institutions, had been the result of Mar Gregorios’ tireless efforts. At present what the Diocese boasts of can be attributed to the great vision of the late lamented Job Mar Philoxenos, the second Metropolitan of the Diocese of Delhi.

The Diocese of Delhi is amongst the thirty dioceses of the Malankara Orthodox Syrian Church that spans both India and abroad. The Malankara Orthodox Syrian Church is an autocephalous, autonomous and indigenous church that belongs to the family of Oriental Orthodox churches. It traces its origin to the evangelical activity of St. Thomas, the Apostle of the Lord Jesus Christ in the 1st century (52 AD). The Church is headed by the Catholicos of the East and the Malankara Metropolitan; presently it is His Holiness Baselios Marthoma Paulose II. The Diocese of Delhi is under the spiritual and temporal authority of its current metropolitan, His Grace Dr. Youhanon Mar Demetrios.
