Rowan Williams has a reputation, quite ill founded, for being unable to communicate clearly and accessibly which comes I think mostly from a wilful desire of many not to hear what he has to say. It is delightful to find in this book such beautiful evidence to bury that reputation as he opens up for us such a rich encounter with complex ideas about faith and the world.
This is an interpretive work, as a companion primarily to the Chronicles of Narnia but ranging widly and freely over C. S. Lewis's othewriting, much of which will be unfamiliar to the general reader, and I will admit that while I know about the Screwtape Letters and The Great Divorce it is only Narnia that I have actually read. As an interpretive work it tells us as much about the theology and world view of Rowan Williams as about C. S. Lewis, I am not suggesting that there is some great distortion going on here just that the very fact that Rowan Williams sat down to write this book, and the themes which he felt were important to include is clearly an insight into his thinking so it is all the richer for giving us a window into two minds rather than only one.
My main encounter with Narnia was the BBC TV adaptations, I then in my late teens I did made my way through most (if not all) of the books, and more recently saw the blockbuster Film versions. I am not someone with a deep knowledge of the text, a point I make to reassure you that reading this book is worthwhile even if you have only very limited knowledge of the "primary" material.
The major point that Rowan Williams makes is that Narnia remains an excellent tool for mission in a world where people are increasing interested in faith/spirituality but disinterested in "Church". The trouble is mostly they have written off Church without encountering the true potential it has - "Sharing the good news is not so much a matter of telling people what they have never heard as of persuading them that there are things they haven't heard when they think they have." (p17) It is a vehicle through which people can see and feel what faith is like freed from the assumptions and baggage that have become encrusted around organised religion.
Rowan quotes a comment from Alsan about the Dwarfs "they have chosen cunning instead of belief. Their prision is only in their own minds, yet they are in that prison; and so afraid of being taken in that they cannot be taken out" and without him making about direct reference the mind jumps to the "New Atheists" and to Darkins in particular - when they not only deny evidence for God but desperately try and manufacture evidence for God's non-existence as if it is rational to bring forward empirical evidence of the non-observation of an unknowable being?
I think this book would make an excellent Confirmation present, certainly highly preferable to the usual flurry of stuffy prayer books that accompany that event. Confirmation is often felt as an anti-climax, built up as a life changing event all too often followed by a sensation of a continuation of the horribly ordinary. A book that looks at the depths of faith and look for those depths outside the "churchy" is just the kind of thing that you need at that moment. It would also make a useful basis for a study group or lent course.
