The government's addition of the words "under God" to the pledge of allegiance in 1954 was a mistake, which should be corrected. Under the First Amendment, our government has no business promoting or otherwise taking steps to establish religion.
I just came across a copy of a sermon delivered by a Mr. Docherty, which apparently was instrumental in prodding President Eisenhower and the Congress to revise the pledge. See http://iltpub.com/blog/a-new-birth-of-freedom/
Upon reading it, I had to lift my jaw off the floor. I can hardly imagine more compelling evidence of why "under God" does NOT belong in the pledge of allegiance than what Mr. Docherty says in his sermon.
The unnecessary insertion of an affirmation of a god in the very pledge that our government calls on its citizens to recite in affirmation of their allegiance to our republic puts atheists and other nonbelievers in a Catch 22: Either recite the pledge with rank hypocrisy or accept exclusion from one of the basic rituals of citizenship enjoyed by all other citizens. The government has no constitutional business forcing citizens to this choice on religious grounds. Yet Docherty made plain that he intended just that, proclaiming that any who "denies the Christian ethic . . . falls short of the American ideal of life." As if he knows.
