Former Archbishop of Canterbury Rowan Williams offers fascinating insight into The Chronicles of Narnia, the popular series of novels by one of the most influential Christian authors of the modern era, C. S. Lewis.Lewis once referred to certain kinds of book as a "mouthwash for the imagination." This is what he attempted to provide in the Narnia stories, argues Williams: an unfamiliar world in which we could rinse out what is stale in our thinking about Christianity--"which is almost everything," says Williams--and rediscover what it might mean to meet the holy. Indeed, Lewis's great achievement in the Narnia books is just that-he enables readers to encounter the Christian story "as if for the first time." How does Lewis makes fresh and strange the familiar themes of Christian doctrine? Williams points out that, for one, Narnia itself is a strange place: a parallel universe, if you like.
