At this time of the Christian year, worship services feature narratives that stretch credulity to the limit. Whether the stories star hayseed shepherds confronted by hosts of glittering angels or desert pilgrims watching something like a dove descend upon a man in a river as a voice from heaven calls him “son,” this is the season of beholding things beyond belief. Ask some who have stopped going to church why they stopped and they may tell you that they could not pretend to believe such things any longer, while some who have stayed will tell you that is exactly the point. Faith means believing the unbelievable, they explain, but if you would rather stay home and watch the Science Channel, then good luck and God bless you. Sooner or later you will realize that the most important things in life cannot be explained.
