Lol it's so deeply ingrained right in front of everyone's nose. Magic Santa, magic reindeer, magic elves and that's just the stuff before propaganda like Rudolph and Frosty came around.
God forbid I get a Harry Potter book on Christmas and being magical thinking into this mess.
The first references we have to Christmas trees are in 16th century Germany. They probably didn't come directly from any pagan traditions seeing as Germany had been Christian for multiple centuries at that point.
I’ll do you one better: Why is Easter a fertility celebration? None of the accounts of Jesus’ resurrection directly tie it to fertility. These became popular as Christians became exposed to cultures that had spring fertility festivals.
The religious celebration of Christmas includes Advent wreaths, church services, and traditionalist music (Joy to the World, Silent Night, etc.) Everything else is the secular celebration.
I'm french and I have always been told that our Gaullish ancestors had festivities going on at that date already and the roman empire made sure to destroy our culture and traditions by replacing our celebrations. They also built churches on the exact same spots as our previous cult places. Like, they even built a new city (Tours) from scratch to make Amboise become irrelevant. Christmas was part of the violence inflicted to our ancestors
One of the main reasons to believe that the birth date of Jesus is not reliable is because we have historical records of when there were censuses, and they tended to not to be in the winter months for fairly obvious practical reasons. There is no record of one occurring in December or anywhere near that time around the supposed date of his birth, so how could Jesus have been born on the way to a census if there wasn't one in December?
The only option is that the date of the birth is out by about 10 years (there was a census in December 10 years earlier) or the month of his birth is out by about 6 months. Which of those two options we don't know but we definitely know he wasn't and couldn't be born at the date that the bible says. The reason people go for the summer birth hypothesis is it's easier to understand how the date could have been moved six months a lot less easy to understand how people could have thought he was 10 years younger than he actually was.
Between the stroke-induced brain damage and the religion-induced brain damage, Sorbo is pretty much at the point where we should wrap him, put in a bow and throw him in the nearest dumpster.
