It reminds me of the conflict between the Saducees and Pharisees - even they weren’t in agreement on anything except they didn’t like Jesus. Acts 23:8 says, “For the Sadducees say that there is no resurrection, neither angel, nor spirit: but the Pharisees confess both.”
They had all kinds of fights about that issue, and that was really a much more religious society, wasn’t it? If they couldn’t agree, what makes Christians think they will all agree enough to run this nation like a religious place?
Quite so - they won’t be able to. There have been attempts made in the past - the English commonwealth and its successor, Oliver Cromwell’s protectorate, in the 1650’s for example. The aim was “Godly government”. It doesn’t work. Theocracies are very bad systems of government, because they are, by their very nature, absolutist in tone. Thats not too bad in a homogenous society. In a multicultural, multi-ethnic, multi-denominational country like the United States it would be an utter disaster.
