This book is meant to bequeath the legacy of a man who lived not simply as a priest of a particular church denomination, but as a person to whom the priestly vocation is considered to be a calling for the human community. The book unravels the radical concerns of the late Rev. M.A. Thomas not only as the Founder-Director of the Ecumenical Christian Centre, Bangalore but also as one who beckons the reader to join him in the ecumenical pilgrimage which is indeed a quest for the unknown.
