A creative, thoughtful, and engaging introduction to the theological quest, Catherine Keller’s much-praised volume On the Mystery is now presented in a new edition, with a new preface and teaching resources. Enlivened with stories, evocative epigrams, and her vibrant prose, Keller’s volume explores and remaps the central mysteries of Christian faith and life—God, Christ, Spirit, creation, justice, and redemption—in light of contemporary science, philosophy, and the fateful challenges we all face today. Theology is disciplined reflection on religion, yet also, Catherine Keller maintains, a personal quest for religious authenticity. Her work On the Mystery is surely the most lucid and compelling introduction to the vital insights, both critical and constructive, of process theology and how it can illumine one’s personal journey toward truth and authenticity. Written for students and lay readers, her volume seeks not to dispel the mystery but to dive into it and embrace the adventurous journey and the life it reveals in God. What emerges then is a new, open-ended quest, a path to a more authentic Christian faith and theology today.
