Mere Christianity


Mere Christianity is a 1952 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 , Christian Behaviour, and Beyond Personality. Lewis was invited to give the talks by James Welch, the BBC Director of Religious Broadcasting, who had read his 1940 book, The Problem of Pain.

Premise

James Welch, the Director of Religious Broadcasting for the BBC, read Lewis's The Problem of Pain and subsequently wrote to him the following:
I write to ask whether you would be willing to help us in our work of religious broadcasting... The microphone is a limiting, and rather irritating, instrument, but the quality of thinking and depth of conviction which I find in your book ought sure to be shared with a great many other people.
Welch suggested two potential subjects. Lewis responded with thanks and observed that modern literature, the first potential subject, did not suit him, thereby electing the latter option, the Christian Faith as Lewis saw it... Ultimately, this was the course he set upon. In the radio talks and the derived book, Mere Christianity, he articulated the congruous tenets of Christian faith.
In the preface to later editions of the book, Lewis described his intentions of avoiding contended theological doctrine, focusing instead on foundational principles and applicable derivations. Along with his use of pithy and succinct language, Lewis was able to more nearly pertain and better appeal his subject to the commonly-educated man, who comprised the vast majority of his audience. Although, he still kept the work plausibly erudite for the intellectuals of his generation, for whom the jargon of formal Christian theology did not retain its original meaning.

''The Case for Christianity'' (''Broadcast Talks'' in UK)

The core of the first section centers on an argument from morality, the basis of which is the "law of human nature", a "rule about right and wrong," which, Lewis maintained, is commonly available and known to all human beings. He cites, as an example, the case of Nazi Germany, writing:
"This law was called the Law of nature because people thought that every one knew it by nature and did not need to be taught it. They did not mean, of course, that you might not find an odd individual here and there who did not know it, just as you find a few people who are colour-blind or have no ear for a tune. But taking the race as a whole, they thought that the human idea of decent behaviour was obvious to every one. And I believe they were right. If they were not, then all the things we said about the war were nonsense. What was the sense in saying the enemy were in the wrong unless Right is a real thing which the Nazis at bottom knew as well as we did and ought to have practised? If they had had no notion of what we mean by right, then, though we might still have had to fight them, we could no more have blamed them for that than for the colour of their hair."

On a more mundane level, it is generally accepted that stealing is a violation of this moral law. Lewis argues that the moral law is like scientific laws or mathematics in that it was not contrived by humans. However, it is unlike scientific laws in that it can be broken or ignored, and it is known intuitively, rather than through experimentation. After introducing the moral law, Lewis argues that thirst reflects the fact that people naturally need water, and there is no other substance which satisfies that need. Lewis points out that earthly experience does not satisfy the human craving for "joy" and that only God could fit the bill; humans cannot know to yearn for something if it does not exist.
After providing reasons for his conversion to theism, Lewis goes over rival conceptions of God to Christianity. Pantheism, he argues, is incoherent, and atheism too simple. Eventually he arrives at Jesus Christ, and invokes a well-known argument now known as Lewis's trilemma. Lewis, arguing that Jesus was claiming to be God, uses logic to advance three possibilities: either he really was God, was deliberately lying, or was not God but thought himself to be. The book goes on to say that the latter two possibilities are not consistent with Jesus' character and it was most likely that he was being truthful.

''Christian Behaviour''

The next third of the book explores the ethics resulting from Christian belief. He cites the four cardinal virtues: prudence, justice, temperance, and fortitude. After touching on these, he goes into the three theological virtues: hope, faith, and charity. Lewis also explains morality as being composed of three layers: relationships between man and man, the motivations and attitudes of the man himself, and contrasting worldviews.
Lewis also covers such topics as social relations and forgiveness, sexual ethics and the tenets of Christian marriage, and the relationship between morality and psychoanalysis. He also writes about the great sin: pride, which he argues to be the root cause of all evil and rebellion.
His most important point is that Christianity mandates that one "love your neighbour as yourself." He points out that all persons unconditionally love themselves. Even if one does not like oneself, one would still love oneself. Christians, he writes, must also apply this attitude to others, even if they do not like them. Lewis calls this one of the great secrets: when one acts as if he loves others, he will presently come to love them.

Cultural impact

Lewis' voice became nearly as recognizable as that of Winston Churchill during World War II, when the talks were given. The book has since become among the most popular evangelical works in existence. In 2006, Mere Christianity was placed third in Christianity Today list of the most influential books amongst evangelicals since 1945. The title has influenced Touchstone Magazine: A Journal of Mere Christianity and William Dembski's book Mere Creation. Charles Colson's conversion to Christianity resulted from his reading this book, as did the conversions of Francis Collins, Jonathan Aitken, Josh Caterer, and the philosopher C. E. M. Joad.
A passage in the book also influenced the name of contemporary Christian Texan Grammy-nominated pop/rock group Sixpence None the Richer. The phrase, "the hammering process" was used by the Christian metal band Living Sacrifice for the name of their album The Hammering Process. The metalcore band Norma Jean derived the title of their song "No Passenger: No Parasite" from the section in the book in which Lewis describes a fully Christian society as having "No passengers or parasites".
