A potential danger to the rest of us (given the right circumstances), is:
[1] Any tyrannical (top-down) mentality who would claim to be the sole, and final spokesperson for God in spiritual matters.
[2] Anyone who actually believes that it's true.
America's Framers didn't. That's why we got a Republic - a bottoms up form of government, undergirded by an impartial rule of law (not by the fluctuating, changing rules of biased, partial men).
