Christian de Chergé, prior of the Cistercian community at Tibhirine, Algeria, was assassinated with six of his fellow monks in 1996. De Chergé saw his monastic vocation as a call to be a person of prayer among persons who pray, that is, among the Muslim friends and neighbors with whom he and his brothers shared daily life. De Chergé's writings bear witness to an original thinker who insists on the value of interreligious dialogue for a more intelligent grasp of one's own faith. Christian Salenson shows us the personal, ecclesial, and theological foundations of de Chergé's vocation and the originality of his life and thought. He shows how the experience of a small monastery lost in the Atlas Mountains of Algeria contributes importantly to today's theological debates.
