Mere Christianity

Mere Christianity is a collection of BBC radio broadcasts by an otherwise relatively obscure Oxford literature professor during the 1940s. Combining his deep and extensive classical learning with an easy and familiar style of writing, Lewis explains in learned but plain language the basic principles of Christian theology, ethics, apologetics, what Christians believe, what they should do, and how they can defend their faith. This may be the best introduction to what Christians believe and why they believe it ever written.
