I had a friend recently point me to the work of Andrew Sullivan by way of The Dish. Feel free to stop now and just go read through the site; it's really, really good. He's heard me speak on Creative Theology and pointed me to this article, The Voice of God in Human Form, a piece on Bach.
The article is a reflection on the book, Music in the Castle of Heaven, which is now on my reading list.
I can't get over the closing line...
We are made in the image of God, the Bible tells us; in the same way, our music is a distant echo of Paradise.
