The late Lewis, Oxford professor, scholar, author, and Christian apologist, presents the listener with a case for orthodox (conforming to the Christian faith) Christianity. Lewis employs logical arguments that are eloquently expressed. He describes those doctrines that four major denominations (Anglican, Methodist, Presbyterian, and Roman Catholic) would have in common, e.g., original sin, the transcendent Creator God, and the divinity of Jesus as well as His atonement and bodily resurrection.
Mere Christianity (along with The Screwtape Letters) is the most popular of C. S. Lewis’s works of nonfiction, with several million copies sold worldwide. Heard first as radio addresses and then published as three separate books -- The Case for Christianity, Christian Behavior, and Beyond Personality -- this book brings together Lewis’s legendary broadcast talks of the war years, talks in which he set out simply to "explain and defend the belief that has been common to nearly all Christians at all times."
It is a collection of scintillating brilliance which remains strikingly fresh for the modern reader, and which confirms C. S. Lewis’s reputation as one of the leading Christian writers and thinkers of our age.
