Is the President a Christian?

Apparently it has been a slow news week, but attention has been paid to a Pew Research poll that found 18% of the American people generally, including 31% of Republicans, believe that Barack Obama is a Muslim.
The discussion surrounding the poll is much more interesting to me than the actual topic of the poll, but let's start with that subject.
Is the President of the United States a Muslim? I'm of two minds here.
First, who cares? When the time came to consider our Constitution over 200 years ago, there was a general outcry that the document would never be approved without an enumeration of certain rights that could not be denied to (given the ignorance of the time) white, male citizens. Over time, our forebears discovered the wisdom to extend these freedoms to all people. The first of those amendments made six sacred declarations: that the government would never be in the business of establishing a church or churches; that the government would never interfere in the rights of individuals to practice their religion; that people would be free to speak their minds; that the press would enjoy that same freedom; that people would be free to associate with whom they choose; and that the people could come to the government seeking justice when wronged. Each of these points is simple and clear. Read them sometime. The significance of the First Amendment for this discussion: It's none of your business or mine whether or not Obama has a religion, and if he does, what it is. That must necessarily be the response of any American citizen who takes our Constitution seriously. Anything less is, by definition, Unconstitutional, and therefore by definition, Un-American.
The second part of what chews on me about this is the arrogance of Obama's political opponents. The exemplary statesman, Sen. Mitch McConnell, was on Meet the Press this morning. Mediator David Gregory asked McConnell, the Senate Minority Leader, about the Pew Poll, wondering how such a misperception could arise. McConnell answered, "I have no idea." Really, Senator? I would have thought by this point that someone would have introduced a fine conservative such as yourself to Fox News, Rush Limbaugh and all of the other people who have committed their lives to convincing Amercans that Obama is lurking in their closets or under their beds, just waiting to get them like those childhood monsters that disappeard when the light was turned on. Disingenuous at best, Senator. A bald-faced lie, more likely.
McConnell went on to say, about his own opinion of Obama's faith, "I take the President at his word [that he is a Christian]." How noble. I'll tell you what, Senator, since you've been so generous with the President, then I'll take you at your word that you're a Christian, too. And I'll take Rush's word for it, too, although he's from Missouri, and just up the road from his hometown of Cape Girardeau, a Muslim father carried out an "honor killing" of his daughter for shaming the family. And, come to think of it, Rush just got married for the fourth time. Kind of violates that whole sanctity of Christian marriage being between one man and one woman (at a time?). (Whoever heard of a nearing-60 multi-millionaire suddenly feeling the need to marry a stunning blonde in her early 30's anyway?)
But I'll take your word, and Rush's, because that's all any of us can do. We take one another's word for it. You don't know what's in my heart, and I don't know what's in yours. But here's what I do know: You and/or I deny a brother or sister in Christ at our own peril.
Whether or not any person is a Christian or not is, ultimately, between that person and God. Again, meddle in that at your own peril. Deny a brother or sister in Christ at your own peril. You might Google "Bible, Jesus, Millstone" and see what you come up with. Read it carefully. And then share with 31% of the Republicans what you find.
