Mar Philoxenos’s schooling began at Bishop Hodge’s High School. He has fond memories of the time he spent playing games like kabadi, thallapanthu kali, football and ball badminton. He made many friends while playing these games and he is still in contact with them. He was also an active member of the school scouts. In school, bishops academic interest was mathematics and he used to help other students in this subject.
His family was highly influential in his decisions to join the ministry. The bishop vaguely remembers the funeral of his great uncle, A M Lukose Kassisham, a Mar Thoma priest , which he attended when he was three years old. There was an unspoken desire in the family for another preist from the next generation to serve the church and society. Mar Philoxenos believes that it was his grandfather Mr A M Mathan's life and witness that influenced him greatly. His grandfather was a retired headmaster when the bishop was a child and he would encourage his grandchildren to participate actively in the church and in community life.
Though it was always on the bishop's mind to go for the ministry, he faced a dilemma, whether he should choose some other prefession. The first step in his decision to go into the ministry was when he opted for the humanities group in college, though he excelled in mathematics. He remembers how Rev. K C Mathew, principal, bishop Moore college, asked him why he took this decision, though his marks pointed in a different directions. He shared with Rev. K C Mathew the desire to entre the ministry , and rev. Mathew agreed that an undergraduate course in humanities was a good choice.
Mar Philoxenos also regularly participated in Mar Thoma students conference during his college days and these conferences were significant in guiding him toward the ministry. He developed a passion for a life of service to God and humanity. As soon as he compelled his B A in E onomis his vicar Rev. A C Zachariah told mar philoxenos that should apply for church sponsorship to pursue theological studies. He was called to appear before the selection board, which consisted of Dr. Yuhananon Mar Thoma Metropolitan, Rev. K I Oommen, Rev. V M Mathen, Rev. C G David and Retired Judge C M Mathew. He was selected to join Bishops college, Kolkatta, for doing the Bachelor of Divinity programme.
Theological studies at Bishop's college was a turning point in his life. The three years he spent at the college strengthened his commitment and gave more focus and purpose to his calling. His academic interest developed during this time under the able guidance of an eminent faculty, which included Rev. Richard Bowie, bishop Sadique ( principals), Rev.Ian Clarke, Rev. W. Westall, Ms. McGregor and Rev. Dr. YesuDas tiwari whose conversion experience, stong faith and religious background along with his caring nature , encouraged and inspired Mar Philoxenos to pursue religious studies. It was at Bishop's college that Mar Philoxenos got his first ecumenical and inter - cultural exposure. He studied along with students from other denominations and regions and was able to appreciate and respect their points of view.
Later he joined Benares Hindu University, Varanasi to pursue a post graduate and then a doctorate in philosophy. He ranked in the university for his MA in Religion and Philosophy. During this period, he also got the opportunity to pursue his Th. M and Princeton theological seminary, USA. The topic of his doctoral thesis was “The doctrine of grace in Vaishnavism and Christianity. It was not just academic interest that influenced him to take up the subject of ‘grace’. When he was studying for his pre degree, a friend, seeing a wall – hanging in the bishop’s house that read “My Grace is sufficient for yu”, asked him, with a hint of irony. “bishop replied, “it will speak for itself.” But the question did not end there for Mar Philoxenos. He took time to think over his friend’s question and this inspired him to take up this topic for his doctoral thesis. Mar Philoxenos recounts that the concept of grace is not an abstraction but a passionate conviction for him, because he has had abundant personal experience of grace at every turning point of his life. He recognizes that he has experienced the all- encompassing grace of God in all things big and small.
Mar Philoxenos was ordained as a priest of the Mar Thoma Church in 1976 by the present Metropolitan, Dr. Joseph Mar Thoma. Rev. A. I. Isaac, as he was called then, was appointed to serve as Vicar of Mar Thoma Churchs in Rajhara, Bilaspur and Nandini and Assistant Vicar of Bhilai Mar Thoma Church. It was Most Rev. Dr. Yuhanon Mar Thoma Metropolitan who sent him off with prayers and gave him crucial advice because two of the churches that Rev. Isaac was to be in charge of were facing some issues. Yuhanon Mar Thoma Said, “don’t take hasty decisions. Listen to people. God will guide you.” Rev. Isaac held strongly to this advice throughout his first tenure in Madhya Pradesh and saw all problems fade away. Held the advice of the late Metropolitan cloes tohis heart and made it a part of his ministerial style. The guidance and motivation of the then diocesan bishop Dr. Philipose Mar Chrusostom were a support and a source of strength during those early days.
His first parish posting is one that the Bishop looks back at with fond memories.. rather than limiting his ministry to the parish level, he tried to relate it maninfully with the needs of society. Many of the activities that Rev. Isaac initiated in his first posting reflect the areas that he is passionate about, like Ecumenical programs, sports to reach out to youth and participation in the concerns of the community.

Mar Philoxenos was very particular that every task or project tghat he took up was in response to the needs of the church and society. This need based approach aiming at the holistic developemt of society can be seen throughout his Episcopal ministry. Seeing the lack of educational facilities in rural north India, he started the chain of “Gram Jyoti Schools” at the primary level.

With a vision to educate the evangelists and lay people of the churches in North India, the Bishop started the Dharma Jyoti Vidya Peeth at Faridabad. This theological institution aimed at orienting students to effective ministry by training them in the rural context and gave importance to mission and developmental studies. Now this institutions is affiliated to the Senate of Serampore University and offers Bachelor of Divinity programmes. The strength of Bishop Mar Philoxenos is not only that he has a far-seeing vision, but that he is able to inspire many to share in his vision so that it becomes a reality. The centres and projects that Mar Philixenos initiated are good examples of this.
In 2001, the Bishop took change as the Diocesan Bishop of the Kottayam – Kochi Diocese and one of his priorities was the development of parishes and mission fields in the high Range.

The ecumenical exposures that influenced him include his participation in the Anglican Liturgical Consultation, the Societas Liturgica congress and the WCC General Assembly at Porto Alegre, Brazil in 2006.
