I think Jesus would be very disappointed at the way we scurry around, buying, exchanging, and then returning gifts for something else.

What? The early Christians were supposed to like, lie low during Saturnalia? Besides, before the Emperor Constantine joined up, he was a follower of the Cult of Mithra, the Bull God, which was very popular throughout the empire, especially with the military. Mithra's birthday was ... you guessed it ... like right around now.
The Christianity of Western Europe was Roman Catholicism. Notice that word "Roman?" The Pope is the "Pontifex Maximus." Julius Caesar held the same title. So what? It would be incredibly naïve for any Christian of whatever denomination to think that this classical heritage counts for naught.
Christianity is our living link to the wonders of ancient civilizations. Deal with it, anti-papists!
