If you don't believe that America was founded on judeo-Christian moral principles, then you are either ignorant or biased. If necessary, I can overwhlem you with a blizzard of quotes and facts from the founding era. Care to take up the challenge of defending your pathetic revisionist position that the United States.
The Roman system did have some influence on western society and our founders, but the bible and the Reformation had BY FAR the most influence. Was the book of Isaiah written before the roman empire? Yes. Look at this verse:
For the LORD [is] our judge, the LORD [is] our lawgiver, the LORD [is] our king; he will save us. Isaiah 33:22
Looky there - the 3 branches of government!! Whadya know! Furthermore, the Roman republic was an utter FAILURE - it turned into a dictatorship because the roman senate did not truly represent the people. They were patricians. Our representative government is different than any other to precede it. Our founders read history VERY CAREFULLY and saw the horrible flaws in not only the roman system but the greek democracy as well. In Rome, the people served the State; in America the State serves the people (at least used to!).
