Do you observe Christmas because you think it's Christ's birthday? Was He born on or anytime near Dec. 25? If Jesus lived on earth today, would He celebrate Christmas at all?

We should sit up and take notice of remarks from a popular American comedian and actor, Drew Carey. At a White House correspondents' dinner on May 5, Mr. Carey directed his comments to the president and vice president and their wives, several military and civilian dignitaries and a host of Hollywood entertainers:
"I can't watch the news lately," he said. "It gets too depressing. What I do now is turn the news off, get out my Bible and turn to the book of Revelation. I start just checking things off … Got it, got it, need it, got it, need it … Red dragon, seven horns, 10 crowns, got it.
"Yeah, I read the Bible a lot, you know. It's just crazy [the way] we celebrate holidays in the United States. I found out just recently there are so many religious holidays we celebrate here in this country that have nothing to do with the Bible at all. Real famous holidays, like Christmas. Christmas has nothing to do with the Bible.
"The birth of Jesus is in the Bible, but not Christmas. The tree is not in the Bible, you know. Gifts—that's not there either. There's no place where it says, '"Celebrate my birthday," says Jesus.' It's a pagan holiday that the Romans invented that we just do. But everywhere you go, I'm telling you, I've seen this so many times, you see a nativity scene and there's baby Jesus, the manger, sheep, shepherds, Mary, Joseph and Santa Claus right in the middle. Who's he? Mary's [birthing] coach? Santa Claus has nothing to do with anything."
Drew Carey actually brought up a serious side of Christmas: that history exposes the holiday as nothing more than a pagan observance dressed up in Christian garb.
Does the question of whether Christmas is biblical or not make any difference? What must Jesus Christ think about the feel-good, commercially driven season that supposedly honors Him?
