As for politics and nationalism ... although people will argue that there is no constitutional statement that says "church and state" must remain separate, if you study history and the founding father's intent upon establishing a government that was equal to all (at least to all white men - absent women and minorities) they intentionally set to keep religion out of it because it was recognized that religion was a division as opposed to a cohesive factor. But America has always had a problem separating religion from politics. It was founded by puritans who were all about governing and dominating others.
Slightly revisionist. They strove to keep Government OUT OF RELIGION. Having come from a place where there was a state religion, they realized if there was to be freedom to worship, the government must be curtailed. It has only been in recent history with the media help that it has been turned around. (reference "1984" ) Most of our founding fathers had & stressed faith. I think it was Adams who commented that our system of government wouldn't work without Godly people. When people stop believeing in God and become their own gods, then whatever they decide to do is ok.Blah blah blah I'm starting to preach sorry.
America is not a cult.It's more like the Disneyland of the world. There are sects that combine their nationalism with their religious beliefs, but from my study of the Bible, God is neither Republican nor Democrat.
No king but Jesus is my motto. If you have the audacity to fly an American flag in church there better be one for Jesus higher on the pole...
