"Mere Christianity" is the most popular of C. S. This book brings together Lewis's legendary radio broadcast talks in which he set out simply "to explain and defend the belief that has been common to nearly all Christians at all times". Rejecting the boundaries that divide Christianity's many denominations, "Mere Christianity" is Lewis's term for the essential Christian message--the theological core on which diverse Christian traditions can stand together.

In the classic Mere Christianity, C.S. Lewis, the most important writer of the 20th century, explores the common ground upon which all of those of Christian faith stand together. Bringing together Lewis' legendary broadcast talks during World War Two from his three previous books The Case for Christianity, Christian Behavior, and Beyond Personality, Mere Christianity provides an unequaled opportunity for believers and nonbelievers alike to hear this powerful apologetic for the Christian faith.
