Don't be so dramatic. Nobody worships C.S. Lewis; words. People quote him and often when he is quoted he sounds pretty orthodox. He never claimed to be any kind of theological expert. He was an expert in English Literature. His understanding of theology was superficial while at the same time often profound. Yet it is that kind of childlike superficial understanding of the Christian life that makes C.S. Lewis' work so appealing.
I wonder shat kind of profound understanding of theology led him to write That Hideous Strength in which the magician Merlin is resurrected to save the world at a time of crisis????
