Many would describe Christmas as celebration of a myth: a “jolly old elf” makes the rounds of the entire world, distributing gifts to worthy children as a follow up to end of the year behavioral admonitions. Some see it as an innocuous cultural exercise that boosts the economy (sorely needed this year) and encourages giving. Others decry this despoiling of the true message of Christmas, pointing out that “Santa” rearranged spells . . .
“Satan.” In reality, Saint Nicholas was a fourth century bishop from Myra, in what is now Turkey (which Paul visited - see Acts 27:5-6):

The American Santa came through the Dutch concept of “Sinterklaas,” and was popularized through the 1822 poem “A Visit from St. Nicholas,” by Clement Moore (“‘Twas the night before Christmas . . . .”). So, even this modern story has its roots in reality. We can celebrate this guy, in context. However, the real Christmas story is about God’s unfathomable gift to humankind. As Peter says, this was no “made up myth,” but the glory of the Lord revealed to humble shepherds in an out of the way Judean pasture. As Peter, James and John later witnessed Jesus unveiled in his majestic glory on the mount of transfiguration, so these shepherds witnessed the beginning of the most profound series of events in human history, culminating in the death and resurrection of Jesus Christ some 30 + years later. These will only be eclipsed by his return in full glory, to establish his kingdom forever. The glory revealed at his birth, which we commemorate every December, is a preview of that which we will experience for eternity. Have a blessed commemoration!
