Fifty years after his death, C. S. Lewis fascinates his readers still. Well established as a key figure in children's literature he is increasingly recognized as a significant Christian thinker. The authors in this volume are from a wide range of Christian traditions—testimony to the reach and significance of Lewis's legacy. The essays return to Lewis's devotional and theological works, assessing their place in his own thought and in the theology of the twentieth century. Lewis emerges as an insightful and creative theologian whose ideas continue to surprise in their sophistication and fecundity. Indeed, it is suggested that he represents a way of doing theology—"mere theology"—which suggests ways in which Christian thought may reengage the complex cultural debates of the contemporary world.
