The central core of the Christian faith is either absolute truth or it is nonsense. Being absolute, the truths which it proclaims also claim to be eternal. If they were not absolute, if they were not eternal, they would not be worth believing. Scientific knowledge, on the other hand, is relative, relative to what at any given moment happens to have been found out about the natural world. A religion which is in constant process of revision to square with science’s ever-changing picture of the world might well be easier of belief, but it is hard to believe that it would be worth believing.
