Now if once we allow people
to start spiritualising and refining, or as they might say deepening, the sense of the word Christian, it too will speedily become a useless word. In the first place, Christians themselves will never be able to apply it to anyone. It is not for us to say who, in the deepest sense, is or is not close to the spirit of Christ. We do not see into mens hearts. We cannot judge, and are indeed forbidden to judge. It would be wicked arrogance for us to say that any man is, or is not, a Christian in this refined sense. And obviously a word which we can never apply is not going to be a very useful word. As for the unbelievers, they will no doubt cheerfully use the word in the refined sense. It will become in their mouths simply a term of praise. In calling anyone a Christian they will mean that they think him a good man. But that way of using the word will be no enrichment of the language, for we already have the word good. Meanwhile, the word Christian will have been spoiled for any really useful purpose it might have served.
We must therefore stick to the original, obvious meaning. The name Christians was first given at Antioch (Acts 11:26) to the disciples, to those who accepted the teaching of the apostles. There is no question of its being restricted to those who profited by that teaching as much as they should have. There is no question of its being extended to those who in some refined, spiritual, inward fashion were far closer to the spirit of Christ than the less satisfactory of the disciples. The point is not a theological or moral one. It is only a question of using words so that we can all understand what is being said. When a man who accepts the Christian doctrine lives unworthily of it, it is much clearer to say he is a bad Christian than to say he is not a Christian.
I hope no reader will suppose that mere Christianity is here put forward as an alternative to the creeds of the existing communionsas if a man could adopt it in preference to Congregationalism or Greek Orthodoxy or anything else. It is more like a hall out of which doors open into several rooms. If I can bring anyone into that hall I shall have done what I attempted. But it is in the rooms, not in the hall, that there are fires and chairs and meals. The hall is a place to wait in, a place from which to try the various doors, not a place to live in. For that purpose the worst of the rooms (whichever that may be) is, I think, preferable. It is true that some people may find they have to wait in the hall for a considerable time, while others feel certain almost at once which door they must knock at. I do not know why there is this difference, but I am sure God keeps no one waiting unless He sees that it is good for him to wait. When you do get into your room you will find that the long wait has done you some kind of good which you would not have had otherwise. But you must regard it as waiting, not as camping. You must keep on praying for light: and, of course, even in the hall, you must begin trying to obey the rules which are common to the whole house. And above all you must be asking which door is the true one; not which pleases you best by its paint and panelling. In plain language, the question should never be: Do I like that kind of service? but Are these doctrines true: Is holiness here? Does my conscience move me towards this? Is my reluctance to knock at this door due to my pride, or my mere taste, or my personal dislike of this particular door-keeper?
When you have reached your own room, be kind to those who have chosen different doors and to those who are still in the hall. If they are wrong they need your prayers all the more; and if they are your enemies, then you are under orders to pray for them. That is one of the rules common to the whole house.
FOREWORD
As a young man, C. S. Lewis had served in the awful trenches of World War I, and in 1940, when the bombing of Britain began, he took up duties as an air raid warden and gave talks to men in the Royal Air Force, who knew that after just thirteen bombing missions, most of them would be declared dead
or missing. Their situation prompted Lewis to speak about the problems of suffering, pain, and evil, work that resulted in his being invited by the BBC to give a series of wartime broadcasts on Christian faith. Delivered over the air from 1942 to 1944, these speeches eventually were gathered into the book we know today as Mere Christianity.
This book, then, does not consist of academic philosophical musings. Rather, it is a work of oral literature, addressed to people at war. How strange it must have seemed to turn on the radio, which was every day bringing news of death and unspeakable destruction, and hear one man talking, in an intelligent, good-humored, and probing tone, about decent and humane behavior, fair play, and the importance of knowing right from wrong. Asked by the BBC to explain to his fellow Britons what Christians believe, C. S. Lewis proceeded with the task as if it were the simplest thing in the world, and also the most important.
