The Lecture that is here reproduced was delivered at the Battersea Town Hall on Sunday March 6, 1927, under the auspices of the South London Branch of the National Secular Society. It is issued in booklet form at the request of many friends. It should be added that the author alone is responsible for the political and other opinions expressed.
As your Chairman has told you, the subject about which I am going to speak to you tonight is ‘Why I am not a Christian’. Perhaps it would be as well, first of all, to try to make out what one means by the word ‘Christian’. It is used these days in a very loose sense by a great many people. Some people mean no more by it than a person who attempts to live a good life. In that sense I suppose there would be Christians in all sects and creeds; but I do not think that that is the proper sense of the word, if only because it would imply that all the people who are not Christians—all the Buddhists, Confucians, Mohammedans, and so on—are not trying to live a good life. I do not mean by a Christian any person who tries to live decently according to his lights. I think that you must have a certain amount of definite belief before you have a right to call yourself a Christian. The word does not have quite such a full-blooded meaning now as it had in the times of St Augustine and St Thomas Aquinas. In those days, if a man said that he was a Christian it was known what he meant. You accepted a whole collection of creeds which were set out with great precision, and every single syllable of those creeds you believed with the whole strength of your convictions.
What is a Christian?
Nowadays it is not quite that. We have to be a little more vague in our meaning of Christianity. I think, however, that there are two different items which are quite essential to anybody calling himself a Christian. The first is one of a dogmatic nature—namely, that you must believe in God and immortality. If you do not believe in those two things, I do not think that you can properly call yourself a Christian. Then, further than that, as the name implies, you must have some kind of belief about Christ. The Mohammedans, for instance, also believe in God and in immortality, and yet they would not call themselves Christians. I think you must have at the very lowest the belief that Christ was, if not divine, at least the best and wisest of men. If you are not going to believe that much about Christ, I do not think you have any right to call yourself a Christian. Of course there is another sense which you find in Whitaker’s Almanack and in geography books, where the population of the world is said to be divided into Christians, Mohammedans, Buddhists, fetish worshippers, and so on; and in that sense we are all Christians. The geography books count us all in, but that is a purely geographical sense, which I suppose we can ignore. Therefore I take it that when I tell you why I am not a Christian I have to tell you two different things; first, why I do not believe in God and in immortality; and, secondly, why I do not think that Christ was the best and wisest of men, although I grant Him a very high degree of moral goodness.
