As I opened window 10, I had to squint to see a small angelic figure holding a book-the traditional Christian symbol for Matthew, the gospel writer. Although Christmas conjures images of angels, the Matthew sign isn't an angel. His symbol is a human being with wings.
I had a hard time finding window nine, an elusive little door hidden in the bushes outside of the cathedral. When I opened it, there was a picture of one of the most famous of Jesus' stories: The Parable of the Prodigal Son (Luke 15:11-32).
