[5][6][7] Gregorios was born in Pallathetta family in the Chathuruthy house at Mulamthuruthy near Cochin, India on 15 June 1848.

His devotion, humility and above all, his ability to sing the traditional Syriac hymns beautifully and perfectly, came to the notice of his uncle Malpan Geevarghese.

The uncle wanted to raise his nephew to be a priest and his family members, who knew Geevarghese's character too agreed to the Malpan's request.

In the late 1890s, many educational institutions were started by the Malankara Church under the initiative and guidance of him and Joseph Mar Dionysius.

He visited almost all the important places of Christendom and led the Passion Week services at Syrian Orthodox Church in the Holy City with accompanied members Geevarghese Dionysius of Vattasseril, Kochuparambil Paulose Koorilos and Osthatheos Sleeba (Later Patriarchal Delegate of Malankara)[13] led as guide.

On his return, he collected a certain amount from all the Parishes in Malankara and sent a Silver Cross as offering to the Holy church in Jerusalem.

Thousands of people and hundreds of priests were present at the funeral who gave testimony of the saintly Gregorios.

On the occasion of 45th death anniversary of Geevarghese Mar Gregorios, based on the decision of the episcopal synod held in 1947, Baselios Geevarghese II, Catholicos of the East and Malankara Metropolitan declared Mar Gregorios as a saint for the Malankara Syrian Church on 2 November 1947.
