MSizer,
Regarding your remark,
"I don't care if I don't accept the divinity of Jesus, I'm celebrating christmas however I want, jesus or no jesus."
Aren't you aware that Christmas has NOTHING to do with a Christ? It was a huge pagan holiday that was celebrated all over the world, many centuries before the mythical Jesus was invented—back to Neolithic times! There was a very important reason why the world was united in this celebration; it was the Winter Solstice, Dec 21, which marked the end of winter and the first day that the Sun would rise higher each day in the sky. This day heralded the planting of crops so food would be again plentiful.
It was a time of incredible merriment, involving gift giving, singing carols, and decorating with candles and shiny ornaments. In Rome, for example, slaves got to switch places with their masters.
After many centuries, the party-pooping Christians gained power, and they wanted to get rid of this pagan celebration. Even Christ disapproved of this heathen holiday, as the Bible clearly attests, when Jesus scolds anyone who puts up a "Christmas" tree:
"Thus saith the Lord, learn not the way of the heathen...For the customs of these people are vain; for one cutteth a tree out of the forest, the work of the hands of the workman, with the axe. They deck it with silver and gold; they fasten it with nails and with hammers, that it move not." (Jeremiah 10:2-6)
This Sun day celebration was far too big an event to sweep away, so the sneaky Christians took it over and made it a celebration of the Son (of God), instead of the Sun.
Fortunately, to this day, most of the traditions and symolism from this glorious old celebration are still all around us. The evergreen tree, the wreath (symbolizing the round sun), the candles and lights on trees and houses (symbolizing the warmth of the sun), caroling, gift giving, and many more.
So enjoy your Solstice celebration this year and be sure to remind your Christian friends to remove their pagan tree from their homes!
