“The central Christian belief is that Christ’s death has somehow put us right with God and given us a fresh start. Theories as to how it did this are another matter. A good many different theories have been held as to how it works; what all Christians are agreed on is that it does work. I will tell you what I think it is like. All sensible people know that if you are tired and hungry a meal will do you good. But the modern theory of nourishment — all about the vitamins and proteins — is a different thing. People ate their dinners and felt better long before the theory of vitamins was ever heard of: and if the theory of vitamins is someday abandoned they will go on eating their dinners just the same. Theories about Christ’s death are not Christianity: they are explanations about how it works.” (C.S. Lewis, Mere Christianity)
Try telling that to a theologian.
Lewis keeps it simple. And on this particular point, I’m thankful.
