As I am sure that you are well aware, the U.S. Constitution does not demand a religious test. In fact, it prohibits it. The oath that the president takes, the only prescribed oath by an elected official in the Constitution, does not in fact mention a god or deity. Some Christian conservatives of the late 18th Century opposed the Constitution because of its' lack of religious language or a statement that we are founded upon Christianity, which we clearly are not. We are a nation founded upon humanist/Enlightenment values.
Well, the U.S. Air Force Academy in Colorado Springs, Colorado, has an oath for new cadets that states at the end, "so help me God." Now, as an official oath, this is very distinct from a president stating, "so help me God", which is unofficial, though still wrong. It is in fact a form of a religious test, or at the very least, the government taking a position on religion, which it should not and cannot do.
The Military Religious Freedom Foundation has been very big in ensuring that the military not to be used as a tool to promote the religious beliefs of certain evangelical officers and their supporters. I urge you to join me and contacting Air Force Academy Commandant Brig. Gen. Gregory J. Lengyel and urging him to ensure the government is not involved in this promotion of religion. His e-mail:
