The author of this book seeks to penetrate the "heart" of Karl Rahner's theology by asking: What does it truly mean to say that Jesus Christ is the redeemer of the world? Rise presents an analysis of the fundamental conception in Rahner's theology, with special attention to the way in which Rahner combines two trajectories, the academic and the spiritual. This combination is the basis for Rahner's interpretation of the (trinitarian) doctrine of God, christology and soteriology. In the final chapter, Rise reflects on the relevance of Rahner to postmodern culture and shows that Rahner's understanding of Jesus is potentially very fruitful in an age marked by pluralism, ethical relativism and the lack of a total vision which could give life a meaning.
