Are you kidding me! Christmas is the most set apart (holy) day on the planet. It starts with "Christmas in July" and continues well into January. The US economy may collapse (certainly many companies would) if Christmas was to suddenly vanish. No doubt there are those on this board that make there living, at least in part, off Christmas. It is embraced by athiests as well as the religious and the worldly, in various countries around the world. Yes, man has indeed created a most holy day. But this is not the first time it has happened, somebody gave us an example;

1Ki 12:28 Whereupon the king took counsel, and made two calves of gold, and said unto them, It is too much for you to go up to Jerusalem: behold thy gods, O Israel, which brought thee up out of the land of Egypt.
1Ki 12:29 And he set the one in Bethel, and the other put he in Dan.
1Ki 12:30 And this thing became a sin: for the people went to worship before the one, even unto Dan.
1Ki 12:31 And he made an house of high places, and made priests of the lowest of the people, which were not of the sons of Levi.
1Ki 12:32 And Jeroboam ordained a feast in the eighth month, on the fifteenth day of the month, like unto the feast that is in Judah, and he offered upon the altar. So did he in Bethel, sacrificing unto the calves that he had made: and he placed in Bethel the priests of the high places which he had made.
1Ki 12:33 So he offered upon the altar which he had made in Bethel the fifteenth day of the eighth month, even in the month which he had devised of his own heart; and ordained a feast unto the children of Israel: and he offered upon the altar, and burnt incense.

The sin of Jeroboam continues nearly unchallenged.
