"- in fact, it was Tolkien that Lewis gave credit to for his reversion from atheism..."

Read Lewis's spiritual autobiography, Surprised By Joy. He specifically cites GK Chesterton, and Chesterton's book, Everlasting Man, many of the themes and arguments resurface in Lewis's Mere Christianity.

You are correct. It was both GKC's writing and 'arguments' with Tolkein, who was his collegue at Oxford at the time.

Thanks for the clarification.
