It's Christmas time and many of us are enjoying family traditions, food and fellowship, but something greater is going on in the spiritual realm. Philip Yancey put it this way: "On earth, a baby was born, a king got wind of it, a chase ensued. In heaven, the Great Invasion had begun: a daring raid by the ruler of the forces of good into the universe's seat of evil." Join Michael, SJ and their wives Robin and Sherry as they discuss Christmas and its significance to us all.
