After hearing your program, I was in favor of leaving the Pledge as it is. However, after pondering and discussing the matter since that time, I have changed my mind, for a troubling reason
that I think has gone unnoticed: the phrase "under God" makes the entire Pledge of Allegiance dangerously vague.
Most proponents take it as a statement of fact, i.e. that our nation *is* under God. Opponents object that it thus undergirds jingoism and an uncritical sense of manifest destiny. It occurred to me, as a rejoinder in the phrase's favor, that perhaps it one might interpret it not as a statement of fact but a qualification: I pledge allegiance to the flag...republic... nation *so long as* it is under God. It might go astray, in the same terms as a secularist might fear, and then it would cease to be under God or commend our loyalty.
Then someone reminded me of the existence of the postmillennialists/dominion theologians/Christian reconstructionists. Now, as a mainstream Christian, I object to this novel reworking of my religion just as much as any non-Christian, and I fear its political agenda just as much. Believing that only Christians (by their own narrow definition) can legitimately wield authority or power of any kind, they are prepared to dissemble in order to acquire it. Any loyalty to the Constitution of the U.S. is purely tactical. As soon as they can, they mean to abolish it and impose the Old Testament law in full. This, they believe, is a prerequisite to the second coming of Christ.
Now, if the phrase "under God" is not construed as a statement of fact but as a qualification, their interpretation could, and probably would, be that the United States at present is not under God at all. Their loyalty is to arrangements that don't yet exist but which they hope to bring about. Therefore, they can recite the Pledge of Allegiance alongside the rest of us, giving the impression that they respect the political arrangements under by which we have agreed to live together: but in fact, they are pledging allegiance to something else altogether! And to which most of us would be vehemently opposed.
Dropping the words "under God" would remove this mischievous back door to treason.
