And Nothing Heard My Scream

[Piggy]

I never claimed the bible is an entirely christian
document. You dodgedily restated my point ....

• founders of America had a biblical
  perspective

Fine. Change Xian to Judeo-Xian in what I said. It stands.

The biblical perspective of the founders can be seen
in many documents but the most obvious example is...

• When in the Course of human events, it becomes
  necessary for one people to dissolve the political
  bands which have connected them with another, and to
  assume among the powers of the earth, the separate
  and equal station to which the Laws of Nature and of
  Nature's God entitle them, a decent respect to the
  opinions of mankind requires that they should declare
  the causes which impel them to the separation.

they were entitled to govern them selves appealing to
natural law (or reason) as Nature's God entitled them
to. The reasoning is that if you can reason to the
idea that you have a right to oppress I can give you
that point. By your reasoning I have the right to
kick your royal butt and free myself of your yoke.
Yet there's more to the declaration than reason of
natural law....

• And for the support of this Declaration, with a
  firm reliance on the protection of divine
  Providence, we mutually pledge to each other our
  Lives, our Fortunes and our sacred Honor.

...if you were risking your life you wouldn't expect
that reason would protect you nor would you appeal to
it. That position is unreasonable.

This is what I meant by "standard tropes of the day". The fact that you choose to cherry-pick these commonplaces and ignore the founders' direct statements on the matter is telling.

I firmly believe that they did in fact risk their lives on the principle that reason -- human reason -- was the salvation of mankind. Aside from these little frills of phraseology, the system of governance described by the documents which form the foundation of American law rests entirely upon the principles of reason and upon the establishment of rationally considered measures to safeguard against the baser instincts of human nature.

And btw, the DoI does not carry the force of law. It was a piece of marketing copy.
