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 worshipers, 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.
But for the successful efforts of unbelievers in the past, I could not take so elastic a definition of Christianity as that. As I said before, in olden days it had a much more full-blooded sense. For instance, it included he belief in hell. Belief in eternal hell-fire was an essential item of Christian belief until pretty recent times. In this country, as you know, it ceased to be an essential item because of a decision of the Privy Council, and from that decision the Archbishop of Canterbury and the Archbishop of York dissented; but in this country our religion is settled by Act of Parliament, and therefore the Privy Council was able to override their Graces and hell was no longer necessary to a Christian. Consequently I shall not insist that a Christian must believe in hell.
