(Book: Mere Christianity by C. S. Lewis, chapter 6, “The Rival Conceptions of God”)
Did you ever notice how some people can take a perfectly innocent and neutral fact, and make it sound incriminating, just by how they phrase it? For example, here’s C. S. Lewis observing that, when we consider all religions throughout history, both Christians and atheists can find things they think are right and things they think are wrong:
If you are a Christian you do not have to believe that all the other religions are simply wrong all through. If you are an atheist you do have to believe that the main point in all the religions of the whole world is simply one huge mistake. If you are a Christian, you are free to think that all those religions, even the queerest ones, contain at least some hint of the truth. When I was an atheist I had to try to persuade myself that most of the human race have always been wrong about the question that mattered to them most; when I became a Christian I was able to take a more liberal view.
Clever, isn’t it? Notice how you can reverse the nouns and say pretty much the same thing: atheists don’t have to believe that all religions are wrong all through, and Christians do think that the main point in all other religions is simply one huge mistake (with the possible exception of Judaism, but that’s Christianity’s ancestor, so naturally they can’t call that wrong).
Here’s another way of looking at it. He could have looked at Greek mythology and Norse mythology and all the many, many gods of the past, and said, “Of all the people who have ever agreed with me about gods existing, at least the vast majority have been wrong about their gods, whereas of all the times atheists have said that someone’s god was a myth, they’ve been right the vast majority of the time. In fact, by Christian standards, there’s only one case where there’s even a possibility that the atheists might have been wrong. So from a historical perspective, theism has been wrong most of the time, and atheism has been right most of the time.”
Of course, that would also be a biased discussion of the facts. Put this version next to Lewis’ version, though, and I think you get a fair and balanced view: you get to see how liberal Christians become when they believe in gods, and you get to see the true value of being liberal minded about gods in a world where such beliefs have historically been found to be wrong at least most of the time.
