The headline of this post by Cynthia Tucker says all that should need to be said about President Obama's religious faith:
Not that it’s anyone’s business, but Obama is a Christian
Most people would focus on the second half, but the most important point is the first. As defined by Article VI of the U.S. Constitution:
The Senators and Representatives before mentioned, and the members of the several state legislatures, and all executive and judicial officers, both of the United States and of the several states, shall be bound by oath or affirmation, to support this Constitution; but no religious test shall ever be required as a qualification to any office or public trust under the United States.
President Obama's religion is no one's business. If he were an atheist, that would be no one's business. That Democrats continually play into the right wing game by going out of their way to prove their religious faith is a continuing problem. When asked about religion, all politicians should be able to say that their beliefs are private. It would be nice to see them refer to Article VI of the U.S. Constitution. It also would be nice to see more people stand up against the very idea that being called a Muslim is a smear. If asked directly whether the president really is a Muslim, the best response the White House could give is the Charlie Chaplin response: President Obama does not have that honor.
But Tucker also has some pointed words about the whole subject:
One of the ugliest things about American public life is the loud, showy religiosity that passes for profound Christian faith — the belligerent and frequently bigoted nonsense that comes from people like Pat Robertson and Franklin Graham. The New Testament is pretty clear about the practices of a real Christian: Matthew 6:6 and 7:16.
