One last thing on Christmas, and then I'll shut up about it:
My mom falls into the category of "mostly secular." The most Jesus ever came up on the actual Holiday is once in a picture book about a tree that eventually became the Cross that my mother read to using year.
Nevertheless, a major part of Christmas for our family growing up was a little thing this church in Missouri puts on called "Journey to Bethlehem." . It's a little,tour leading to the Nativity, basically, with Angels and shepards and Herrod and 3 wise men and all that. In recent years, I've even become an almost-friend of an individual there who has played the innkeeper since it started(as a kid, I would try to play little pranks on him, and he would get me right back).
I still go every year that I can. Once I took my niece and nephew in law(who are Christian), but usually, it's just myself and Squirrel.
I know the places they get the gospel wrong. I don't even come close to believing the central contention of the story they tell.
It doesn't matter one hit to me. It's part of my Christmas tradition, whether I believe a word of it or not, and yeah, I'd be very upset if it went away one day.
And that pretty much sums up Christmas for me. The personal and family narrative far outweigh the meta-narrative.
