I have one question -How does one truly defend and uphold inalienable rights endowed us by the Creator when one does not consider the Creator to exist?
In my opinion -this belief and acknowledgment of the Creator in context with the people and the role of government is truly what separates America and our form of government from all the others.
You are of course referring to the one mention of a creator in our founding documents. In my opinion, Jefferson was looking for a way to de-legitimize the authority of the British crown over the colonies, and he hit upon this construction. (Not that it would have made much difference if we had lost the war).
It's also interesting that the British state, made up of people who were nearly all believers in a traditional, trinitarian Christianity based on an inerrant Bible, were opposed to a loose association of colonial leaders - some clearly deists and others with their own freelanced views of God and the Bible - and God, if he indeed took a side, was apparently on the latter.
Which leads to another question. If God wants people to be free citizens, and if He intends them to have inalienable rights which no state can extinguish, why did nations based on that "endowment" not come into being with the start of the Christian era? What was it about the founding generations of Americans that made them different, not just from all other nations but from all preceding Christian nations??
