Perhaps Christianity does not so much need to be defended as to be accurately described. If this is the case our candidate for most accurate description and most universal intelligibility is this book. Originally a series of radio broadcasts, Mere Christianity
retains a humble conversational tone without sacrificing the essential philosophical and theological soundness and depth of Lewis's thought. 175 pp.
An Eighth Day View:
One of the most popular and beloved introductions to the concept of faith ever written, Mere Christianity has sold millions of copies worldwide.
The book brings together C. S. Lewis's legendary radio broadcasts during the war years, 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 provides an unequalled opportunity for believers and nonbelievers alike to absorb a powerful, rational case for the Christian faith.
