Pretending "Christmas" has anything to do with Jesus just because it was decided to turn a pagan holiday (Dec 25) that had ALWAYS been a pagan holiday celebrating the birth of every tom-dick-harry-pagan-'god' that's come down the pike (https://www.biblechristiansofgod.com/the-list-of-pagan-deities-born-dec-) is no different, no less a slap in God's face, than the change of His Holy 7th day Sabbath to 1st day Sun(god)-day worship by the authority (alone) of the Roman Catholic Papal church. A fact which they (the RCC) BOLDLY proclaims and takes credit for based on *no* scriptural support whatsoever.

The best exegesis on the subject you'll ever find done by Roman Catholic theologians themselves
