A lesson from Justice Scalia on the most important event in human history

Ed Hartnett passes along this story about Justice Scalia that reveals much about him as a man of faith, as a student, and as a teacher:

He spoke at Seton Hall on our Charter Day -- essentially the school's birthday --  about his experience as a history student at Georgetown. He recalled a professor who asked him, "what was the most important event in history?"  He answered with several significant events that he had learned about as a history major. The professor responded "no" to each answer. Finally, he gave up, and the professor provided the answer, "the Incarnation." 

Professor Hartnett gets the effect of this just right: "The lesson stayed with him, and the story stayed with me."
