To get a feel for my perspective on this: I am offended by american flags in church.
Want to know how to view our leadership? Read what Jesus and the apostles said on the subject.
Or, as one pastor once asked: Where would the early church have been if they had put their faith in rome. The US is simply the temporal government that lays claim to the territory I spend most of my time in while visiting this very temporal world.
There is a Christian flag, and there is a U. S. flag.
It's my take that neither flag reaches it's full potential in this nation, without the other.
Christianity is given freedom to fly here by our Constitution. It's observers should be safe and prosper here because of that.
The United States Founding Documents which serve us best, are best observed and enforced through the eyes of Judeo Christian ethics.
It's not a marriage made in heaven. It's a marriage made because of heaven.
As we veer away from the Judeo Christian path, the more this place will resemble hell.
