Yes, he should swear on a Bible

Dean Obeidallah has this idea that presidents should not take their oath of office with their hand on a Bible.
In an essay he wrote for CNN.com, Obeidallah says the Constitution is the document to which the president swears and that is where his hand should rest. It’s also interesting to note that this man is a former lawyer and a “political comedian.” When I read the essay I kept looking for a punch line. I didn’t see one, so I’m assuming he’s making a serious point.
Well, President Obama has just taken his second inaugural oath and it has been reported by various media around the world that he took the oath with his hand on an old Bible once used by President Abraham Lincoln.
I got to thinking about what the CNN essayist said and wondered for a moment what kind of firestorm would erupt in the conservative media had this president taken his oath on a volume other than a Bible.
Every conservative political commentator’s head would explode. Heck, many of them already have accused the president of being a closet Muslim who sympathizes with terrorists … despite his many declarations of his Christian faith. That doesn’t matter, they say. The president is lying and he really hates Christians, the nuttiest among them say.
An acquaintance of mine once said the president took his fist oath with his hand on a Quran – Islam’s holy book. I looked at him, stunned to say the least. “How do you know that?” I asked. “It’s all over the Internet,” he said with as straight a face as I’ve ever seen someone utter such bilge. I told him – in not-very-polite terms – that what he had just said was nothing but unadulterated bull corn (or a term to that effect). We haven’t spoken to each other since.
The president takes what’s been viewed commonly as a sacred oath. Thus, in my view it is appropriate for him to place his hand on a Bible if that is what he prefers. The Constitution does not require it of presidents. But I see nothing wrong with him using the Bible as an affirmation of the oath he takes to serve the United States of America.
And, let’s not forget, presidents have the option of ending the oath with the “so help me God,” which Barack Obama has done twice.
Congratulations on your second inauguration, Mr. President. God bless you.
