Here is thing.. That was 1776, this is 2007... Things are kinda different now...
The assertion was made that Christian belief was not a requirement for office holders. Clearly this was not the case during during the founding era and long after.
Things are different now. Conditions are worse. Lying sons of Belial can get elected and completely break they're sworn word. The printed word means nothing. It means what their judges say it means. Christians (what the Bible defines as a Christian) have a long tradition with covenants and constitutions and strive to honor the written word, and not misconstrue it.
