It's taken a while to persuade the Internet to upload my homily for Christmas but it can now be found by following the link. Basically the drama of Christmas speaks to us, and the re-telling of the story resonates with our experience. The coming of Christ in his Nativity should speak to us where we are and touch us where we need it. This could sound trite and rather simple... But what is more simple than a birth? And what is more necessary to new life?
