Fr. Thomas Dubay, S.M. The highly regarded Dubay (Fire Within) presents a thorough and concise analysis of the critical questions and issues concerning faith and certitude in our day. Written in a very readable, inspirational and sometimes humorous style, Dubay cuts through the relativism and skepticism of our time and exposes the deepest roots of error, whether scientific or religious. He shows how anyone committed to an honest search for truth and goodness can attain a rock solid religious certitude that will not be shaken by developments in human events and academic studies.
