A few years ago a friend who is now a priest told me about an interesting Nativity scene figure. He's called the "caganer." Ever heard of him? Most Americans have not. He is most popular in northern Spain and southern France and in Latin American countries. He is a little, red-capped fellow, squatting in an inconspicuous corner of the scene, and he is - well - "relieving" himself. The point being that when Jesus came among us as a man he entered all that being human entails - warts and all.
The caganer is also a reminder to us not to be caught off guard when Jesus returns. Even the blind were able to recognize the healing power of Christ when he was among them. We who have eyes to see, ought - and not get caught with our pants down!
