It is not over. Despite the lull that follows the frenzy of flying wrapping paper, the aching bellyful of cookies, and an overload of carols, Christmas does not end on Sunday. It is only the beginning of the season, of the “twelve days of Christmas” that the famous song describes. It encompasses the veneration of the magi at Epiphany, the Solemnity of Mary, Mother of God, and (in many faith traditions) the baptism of our Lord. That’s a lot of goings-on for a period most people consider a mere aftermath.

I suppose many of us experience the post-holiday blues. Maybe it wouldn’t be so bad if we saw Christmas Day as less of an ending and more of a beginning. It is the incarnation of God as flesh that is the true gift of Christmas, and that does not end when the last gift is unwrapped. Imagine the enormity of it! God, greater than any of us can imagine, makes himself small, as small as a baby in a manger, just so He can touch us, live among us, connect with us. “God became flesh because flesh is loveable.” That’s my favorite quote from author Mary Gordon’s The Company of Women. And isn’t it so? God became flesh in the most loveable way: as an infant. We can dislike grown-ups, roll our eyes at bratty toddlers and moody teens, but babies? You have to be made of some pretty stern stuff to hate a baby.

It is the unfolding of the Incarnation that we celebrate post-Christmas Day: The wise men from the East following the star to adore the newborn Savior. (They understood the magnitude of the situation.) The child’s first presentation at the temple. The evasion of Herod’s plans to kill Jesus. (Even then, the powers-that-be wanted Him dead.) All this, reminding us of the tension of God-become-flesh, for flesh is fragile, too.

This fourth week of Advent may be the end of the waiting, but it is not the end of the celebrating. We’ve only just started that. Keep it in mind. And have a blessed and merry Christmas!
