But also note that when religion becomes government, as in Europe's dark ages or in present day Middle East, it becomes, inevitably, no better than just another amplifier of man's evil. Originally, the US constitution recognized this and created the best government ever known to man. It recognized and supported religion, but didn't rule by it. That has been completely misinterpreted by liberals, who hate religion and the constitution.
Agreed, wgflyer.
The only theocracy that has any hope of surviving is one where the Lord JESUS CHRIST is sitting on the throne of power, as says the old nugget: There can be no peace without the Prince of Peace. That is, however, for a future time.
We taste of this kind of government when we allow the Saviour His proper place upon the throne of our individual lives as we accept His authority as Lord over all. This is what helps us to make the right decisions - such as, to whom shall we vote for?
Indeed, I would not like to see any religion, even mine own, become the religion of the state. I believe that our founding fathers, though not specifically Christians, but biblically-minded, saw the best government as that where, as you state, man is permitted to rule over his own affairs and conscience - rather than having some despot - as I fear we now have.
Thank you for reading.
