Happy spring equinox!
We had a picnic today. I suppose all I will say about it is that it is like celebrating New Years, and Thanksgiving, and that God made spring and the seasons.
While Halloween is a pagan holiday, and trick or treating being a reenactment of evil spirits on a rampage and/or druids seeking donations/human sacrifices on pain of cursing: with Christmas on the other hand, every central tradition of Christmas is Christian in origin.
The date of the 25th of December is never the winter solstice: where did it come from? Yes it was not Christ's birth: it was a calculation of his conception, which was placed on either the 25th of December or the 6th of January (nothing to do with the solstice), hence the twelve days of Christmas until Epiphany. I think the Orthodox churches focus more on the 6th of January.
Incidentally, though this is not so common knowledge as what I just mentioned, the twelve days and Epiphany were celebrated before Saturnalia was moved from a summer to a winter celebration. So it is more a situation of pagan's trying to interfere with an originally Christian celebration.
The Christmas tree was set as a replacement of the thunder oak of Thor by the missionary Boniface. This is practically a biblical quote, where the evergreen (cedar in the Bible) is connected with worship, while the oak is connected with paganism. Though the oak is in one place connected with Christianity (
Isaiah 6:13).
Santa Claus is St. Nicholas, who did in fact have give gifts secretly and in at least one case put them in people's shoes. Yes it is better I believe to teach about St. Nicholas than to pretend about a made up version of him, but I have heard many strange things against Santa Claus, and many who celebrate Christmas make a point of leaving Santa Claus out. This would be to depart from the original meaning of "Santa Claus" as much or more than pretending he is some magical character who can fly.
This pretty much leaves the Yule log and mistletoe, and yes, we do not include these in our celebrations.
Pagans will have celebrations in winter; but this does not mean that winter, or the solstice, is at all pagan, or off limits to the people who follow the God who promised that the seasons would forever be under his command.
