Actually chistmas is a pagan holiday. The 25th is really the sun-gods birthday or the celebration of sol-ivictus birth day. Constitine included chrisitans on this holiday to push christianity and actually a majority of christian holidays where stolen from pagans.
Christmas = Christ- Pagan Mass.
Jesus birthday was never really known. As he is a mythical god and was made up. So when you use a book as metaphorical as the bible, it's a great way to confuse and trick people . Leaving the bible so open ended makes it harder to nail down facts and interpretations. Thats why you got so many different religions out of one book. Sh-t one religion used the bible to write another book. Mormanism. My opinion but I think Religion is a joke. I'm sorry but it is and if people believe in it, I got a bridge for sale in Brooklyn. God blessed it.
