Christ in Christmas

On the way home from work on Friday, we were discussing a radio show JtM had heard that week. It was about keeping the "Christ" in Christmas. From the way the discussions were going, it sounded as if the speakers were more interested in making sure people said "Merry Christmas" rather than "Happy Holidays" and that no one write Xmas.

I wonder, though, are there better ways to keep Christ in Christmas? Alternative giving, feeding the homeless, caring for children, telling your friends about the transformative power of grace? Are there ways to keep Christ in Christmas?
