That is a complete fabrication....
Although who gives a shit. No one ever said merry christmas in the bible. It's not a Christian holiday. It's a commercial holiday that was fabricated in the Victorian period...
Jesus was not born in a manger, not born on December 25, there was no star, no wise men, he wasn't the son of some fictitious god.... He was just a Jew trying to reform his people (1 among many at the time).
All the other details were fabricated 40 to 80 years after his death drawing on Old Testament and common gospel sources for inspiration.
Actually his birth date was decided by a vote.
Apparently, even his so called followers don't think he was very special either.
On his birthday (hahahaha thanks Constantine) how do they celebrate it? Do they teach their kids about the true Jeus who was a brown man from the Middle East and reflect upon his legacy and teachings? Of course not, instead they celebrate the holiday with a story about a fat white man that climbs down chimneys and leaves gifts.
Easter is even more hilarious as it doesn't even involved another man at all, instead it involves a giant rabbit that hides psychedelic eggs in the yard.
The Son Of God can't even get his own holiday without having to share it as second fiddle with another fictional character.
