I read somewhere that Dec 25 is the first day AFTER the winter solstice where the sunrise was noticeably earlier than the day before—thus indicating the swing back from the dark.
I an not saying this is why Christmas is on that day. But rather, if you were going to celebrate the end of the darkness, Dec 25 is a good day to do that.
AMEN!
A way to WELCOME the LIGHT OF THE WORLD.
