True enough but at the same time Christians should be encouraged to detach themselves from, for lack of a better term, the 'spirit of America', which many still believe is somehow synonymous with Christianity itself.
I see in the church today this false idea that the ideals of American revolution and ideology of human liberty somehow overlap with the way of Christ laid out in the Gospel, but actually one may as well be mixing Christianity and Mormonism.
The United States as a political community is a kind of Civil Religion, based in the mythic Greek worldview, as Shining City that has emerged, through man's reason and willpower, out of the darkness of monarchical superstition, to allow man to live in the light of liberty to basically think and do whatever he pleases, including ruling himself by the stated powers of his own collective human will (democracy / republicanism) . Everything about it is anti-Gospel and anti-Christ... (and indeed the American Founders and Framers explicitly rejected the deity of Jesus Christ).... they just use the word "God" a lot. It's actually quite disturbing how hooked into Americanism the church is.
I don't think we need to actually do anything about it except realize all the America stuff is meaningless. We have a similar regard for America as Judah might have had while living in Babylonian exile. Yes, we obey our authorities, accepting that God has placed them there, but we don't live in this fairytale that we share in the same object of veneration or spiritual values, as Christians today try to impose upon pagan America.
Have no doubt about it, the United States, in fact in the West, was based on Judeo/Christian values. They didn't always get it right, but it has far better for
people in America and the West than in other parts of the world.
"The Book That Made Your World," by Vishal Mangalwadi, gives many examples of how the West and the United States were developed from Judeo/Christian values found in the Bible.
Vishal Mangalwadi, born and raised in India, shows how British Colonialism and the Christian values they brought, made life better for Indians wherever they were able to. I thought this was strange until I started reading how live was like where the Hinduism and Islam were the primary religions of the culture, and how untouchability did so much harm to people over the centuries. He writes about how
when he was young and went to England the first time and saw how much better life was there than in India. As he shows, it wasn't because the English oppressed India, but rather the Bible which centered around the culture, changed people for the better. He points out that the first hospital and first schools were built by Christian missionaries. In fact, he shows how wherever colonialism developed in various Asian nations, life got better.
Outside of Christianity, it was rare that the people would go to help strangers not part of their culture. Yet, Christians went to all parts of the world and made things better for people who were strangers to them.
Even after WWII, Japanese POW's were shocked at how Japan treated their POW's, and how well they were treated here in the States. Why did they treat them so well? They learned that it was how they were raised in Christianity.
Even today with our nation rejecting God, we still have Jews and Christians bringing aid to other people of the world.
We may be a country where many of the Founding Fathers were deists, but even they were influenced by the Bible in the culture they lived in. They may have rejected Christian religion itself, but the values found in the Bible, were still ingrained in them.
