New book, still in shrink-wrap. Green cloth hard covers with gilt titles on the front, back and spine. Mere Christianity is a theological book by C. S. Lewis, adapted from a series of BBC radio talks made between 1941 and 1944, while Lewis was at Oxford during the Second World War. Considered a classic of Christian apologetics, the transcripts of the broadcasts originally appeared in print as three separate pamphlets: The Case for Christianity (Broadcast Talks in the UK) (1942), Christian Behaviour (1943), and Beyond Personality (1944). Lewis was invited to give the talks by the Rev. James Welch, the BBC Director of Religious Broadcasting, who had read his 1940 book, The Problem of Pain. In 1943 Great Britain, when hope and the moral fabric of society were threatened by the relentless inhumanity of global war, an Oxford don was invited to give a series of radio lectures addressing the central issues of Christianity. Over half a century after the original lectures, the topic retains it urgency. Expanded into book form, Mere Christianity never flinches as it sets out a rational basis for Christianity and builds an edifice of compassionate morality atop this foundation. As Mr. Lewis clearly demonstrates, Christianity is not a religion of flitting angels and blind faith, but of free will, an innate sense of justice and the grace of God.
