building on the foundation of the founding fathers

As we see our nation changing and dividing, I think 'maybe if we just taking one step back and a deep breath.' This political civil war, although not fought with guns, is truly crippling our nation. Are we like so many civilizations in history: it will take a common enemy to unite us? Apparently that is not the case or someone hasn't made the case strongly enough. Our nation has been at war for over three years [this time] and the chasm is widening, although we continue to move, in a 'national' direction. [Isn't that term bipartisan a piece of grammar?]
I am neither Republican nor Democrat, so I get mail from both sides. I am not a political matahari, but in listening and reading, I find so little actual difference. The Republicans use the word "faith" in a very general, vague way in which it can apply to any religion, as; we are a nation that is free to worship as an individual sees fit, because your leaders say so. The Democrats say believe what you want or nothing at all, 'just believe me,' your trustworthy representative. I have trouble hearing any real difference. And don't even get me started on the NAFTA Highway. I am fully convinced Bill Clinton did more to rally the Republican Party than any Republican in American History!
Now, on with my rant. I have read articles and posts that declare our founding fathers to be everything from devout Christians to deists to plotting Illuminati. For the sake of argument, because as history continues to be "re-evaluated" which I simply refer to as rewritten, there will be no way to verify convincingly.
If in fact our founding fathers were devout Christian men that based their decisions regarding morals and values upon the Bible, how did we come to have a revolution?
The same scriptures that justify and defend our nation's leaders and render us to be law abiding tax paying citizens were in their Bible, also. Romans 13:1, 2 is in the King James Version of the Bible, and it was practically still "hot off the press!" I also checked with another Version claimed to be used at that time . . . Geneva 1599? It doesn't read much differently. What about paying taxes in "rendering unto Caesar, that which is Caesar's?"
If these men were the devout Christians that many say, how did the Boston Tea Party and the Revolutionary War become a good idea? And if they were deists, would they really have fought with the fervor that they did for an abandoned universe? And if they were plotting Illuminati, aka: powerful members of the freemasons, their membership is dwindling.
My concern and question is: What will happen in America if we reclaim the foundation of the founding fathers? If high taxes and loss of liberty were reason to revolt in the 1700's, what will be the cause in this century? Has the definition of treason become more subjective or less subjective in our Act of Patriotism?
Regardless of their religion, regardless of our politics . . . if George W. and Thomas J. and John H. were here today, what would they advise?

Except the LORD build the house, they labor in vain that build it: except the LORD keep the city, the watchman wakes but in vain.
