Mere Christianity is a theological book and is considered a classic of Christian apologetics, the transcripts of the broadcasts originally appeared in print as three separate pamphlets: The Case for Christianity (1942), Christian Behaviour (1943), and Beyond Personality (1944). Lewis, an Anglican, intended to describe the Christian common ground. In Mere Christianity, he aims at avoiding controversies to explain fundamental teachings of Christianity, for the sake of those basically educated as well as the intellectuals of his generation, for whom the jargon of formal Christian theology did not retain its original meaning. Clive Staples Lewis (1898-1963) was a British novelist, poet, academic, medievalist, literary critic, essayist, lay theologian, lecturer, and Christian apologist. He is best known for his fictional work, especially The Screwtape Letters, The Chronicles of Narnia, and The Space Trilogy, and for his non-fiction Christian apologetics, such as Mere Christianity, Miracles, and The Problem of Pain.
