So, the day is finally here. It’s Christmas (unless you are part of an old-calendar Orthodox parish).

In shopping-mall liturgy, today marked the end of Christmas — which began just before Halloween with the running of the first cable-TV holiday movies. If you are part of a congregation that is into things like Christian tradition (or Charles DIckens), then the season has just started. In a way, old-school Christmas is rather nice — since the advertising tsunami has passed by.

I realize that some people have been greeting friends and family with “Merry Christmas” — or “Happy Christmas,” for Brits — for weeks now. Others have been more careful and stuck with “Happy Holidays.” Some of us old-school folks waited, you know, until Christmas to start saying, “Merry Christmas.”

But is this choice actually POLITICAL, in this age in which everything can be interpreted as a statement against or in favor of you know what and you know who?

What about on Twitter? What language did you use?

Yes, it’s time for another Ryan Burge chart.

Thank you, President Trump!

Because of you, my family was able to celebrate and say "Merry Christmas" this holiday season. That's something we haven't been able to do since ... last Christmas.

As GetReligion readers probably heard, the president congratulated himself in a Christmas Eve tweet: "People are proud to be saying Merry Christmas again. I am proud to have led the charge against the assault of our cherished and beautiful phrase. MERRY CHRISTMAS!!!!!"

So much winning — and Christmas spirit!

But personally, I identified with the response of Ed Stetzer, executive director of the Billy Graham Center at Wheaton College, to Trump's tweet: "So, was this a thing that I missed? Were some of you really ashamed of saying Merry Christmas before the election? Or afraid to? Teach me — are you proud and more bold now? What?" (See Stetzer's Twitter timeline for some excellent feedback that he received.)

Here's the deal, though: Trump's emphasis on Christmas — like his "Make America Great Again" slogan — has tapped into something deeper than saying Merry Christmas, as a nice PBS Newshour segment noted Monday night.

I recall that when I interviewed Robert Jeffress, one of Trump's key evangelical advisers, earlier this year, I asked about the Christmas issue.

Jeffress told me:

People say, 'Well, what’s the big deal about Merry Christmas? I think President Trump understands that Christianity has been marginalized in our country. For the two years I’ve known him, he’s talked about that quite a bit, the marginalization of Christianity. He certainly believes that people of all faiths or no faith ought to have the right to practice whatever faith they have. But he’s noticed the decline of Christianity in America, and that concerns him.

Real war on Christmas or not (for what it's worth, the Washington Post's opinion Twitter account thought Dec. 25 was a great day to question Jesus' existence), Trump's Christmas focus seems to have resonated with much of his evangelical Christian base.

Merry, well, happy, uh, Trump-era SOMETHING from Twitter, care of Ryan Burge

Happy Trump-idays! The real reason for so much winning and saying 'Merry Christmas' this season
