If it's truth you're looking for then celebrate in the fall when he was born. :dizzy:
Naw...no need to celebrate His bday on a specific date...
And not with unleavened bread...that's for Passover as Paul said...
And certainly not with all the other stuff like Christmas Ham...can you imagine?
"Hey baby Jesus Happy birthday on what was mithra's solstice party...here is some ham you can eat next to the tree we cut and brought inside to decorate with gold and silver...if you were good a man dressed in red will reward you with earthly riches...have some sugar and alcohol..."
