...decorating evergreens is in the Bible?
Yule logs? Mistletoe?
What was the exact date of the birth of Christ anyway?
Why’d they choose three days after the winter solstice?
An explanation given to me, with no proof or biblical reference, but which I like because of it's symbolism, goes like this.
The world became darker as mankind drifted farther from God, much like nights get longer as we approach the winter solstice. More darkness and less light in each day as we approach the solstice.
But with the birth of Christ, His light shone for all and world became brighter, much like days begin to get longer after the winter solstice. More light and less darkness in each day.
I like the imagery.
