His Grace was born to Mr.K.T.Thomas and Mrs.Aleyamma Thomas on the 3rd of April, 1938 in Kizhakkethalackal family at Puthencavu, Chengannur, Alappuzha Dist. Being the grandson of Kizhakkethalackal Thoma Kathanar and the nephew of the late Geevarghese Mar Philoxinos (Puthencavil Kochuthirumeni), His Grace thus inherited the rich priestly heritage of Kizhakkethalackal family. Kizhakkethalackal family is a branch of Mavelikara Vadakkethalakal Mahakudumbam. His Grace is 42nd in the priestly generation and the 5th bishop in the Vadakkethalackal family. The other bishops in the family are Simon Mar Dionysios, Yuakim Mar Ivanios, Abraham Marthoma and Geevarghese Mar Philoxinos.

These six schools including The Gujarat Refinery English Medium School are under The Trust of the Society of St. Basil; the founder of the Society of St. Basil was the late Geevarghese Mar Philoxinos of Puthencavu .

Being an educationist, his approach is completely ‘child oriented’ and nothing is more important to him than the welfare and all-round personality development of the students. He has novel ideas for improving teaching techniques and he inspires even the mediocre students to excel. Consequently, today there are hundreds of “his children” who are serving the society as successful doctors, engineers, teachers, researchers, executives etc.

Besides being the Metropolitan of the Diocese of Chengannur, His Grace served The Malankara Sabha in various capacities; such as the Secretary of The Holy Episcopal Synod, the Manager of the Catholicate & M.D. Schools, the President of Akhila Malankara Balasamajam, the President of Akhila Malankara Prarthana Yogam and the President of the Church Accounts Committee and the President of the Church Finance Committee.

A Coaching class for the children of classes 5th to 10th & 12th appearing for Sunday School Competitive Examinations was first introduced in this Diocese

Mar Philoxenos Research & Guidance Centre & Library, Vidyajyothi – a unique programme aiming at excellence in secular education and Philox School of Liturgical Music are three innovative ideas launched by His Grace in the diocese of Chengannur. Every year His Grace gives training to the Parish office bearers like the Vicar, the Kaikaran (Treasurer), the Secretary and the Managing Committee Members.

The “Daivavili Sangam”, a nursery for budding priests and nuns, is a unique activity of this Diocese. A Pre-Marital Counseling Programme was started in this diocese which conducts its sessions every 2nd Saturday of the month.

The Suvisesha Sangam – a fellowship of all the office bearers of the various spiritual organizations in the Diocese is the missionary wing of the Diocese.

The Parish Council is yet another innovative idea introduced by His Grace in this Diocese. The Vicar, the Kaikaran, the Secretary and the office bearers (Vice-President, Secretary & Trustee) of various spiritual organizations in a Parish constitute the Parish Council. They meet once in three months and review the functioning of the spiritual organisations in the Parishes.

The Philosophy of His Grace is “Search for Excellence” in all spheres of life.
