In Hebrew and Arabic, the words Amen and Amin--the most frequent conclusions of prayers--derive from cognate consonantal roots. The Greek and other versions of the Hebrew Bible continue to use the word Amen; the New Testament follows suit. The basic meaning of Amen or Amin in all three scriptures is the same, a passionate address to God: 'I entrust myself to You; I put my faith in You, I keep faith with You.' It is the cry of a person struggling to grasp and be grasped by God.

Amen: Jews, Christians, and Muslims Keep Faith with God examines faith as it is understood by Jews, Christians and Muslims; it does not aim to be a work of systematic theology or a lengthy explication of the contents of different faith traditions. It offers Jews, Christians and Muslims several approaches to faith as a category of human experience open to God: a faithful God who reaches out to grasp the faithful human being at the same time that the faithful human being reaches out to grasp a faithful God. This two-sided faith, divine and human, lies at the center of each faith tradition. The book examines faith as one might examine a gem, gazing at different facets in turn. In this process, Patrick Ryan, a Jesuit who has lived for decades in Africa as well as in the United States, shares the personal reflections of one who has tried to live a life of faith not only in the company of fellow Christians but also in the company of Jews and Muslims, friends for many years. The work as a whole, and each chapter within it, begins and ends with reflections shared with an anonymous but real person who has struggled with faith for all that time and who continues the struggle with faith even today.
