This book offers a critical appraisal of the theology of Karl Rahner with particular attention to the account of the phrase "God is love." Beginning with a review of Rahner's understanding of God and the problematic nature of God in contemporary theology, Mark Taylor uses process philosophy to define God as "essentially love of others." This work represents both a contribution to the secondary literature on Rahner and a creative effort to discern divine reality from the perspective of Christian theology.
