Have you read "Mere Christianity" by Lewis? Or "The Screwtape Letters"? You need not make assumptions about Lewis' Christian views, he did not hide it. He was not a Catholic, to Tolkien's dismay.
You slander someone who you would consider a powerful ally, if you actually understood what you were talking about. I fear you will have no allies at this rate.
