To become truly great, one has to stand with people, not above them.
Charles de Montesquieu
This is the "means for Christian religion", as far as Montesquieu is concerned. The Christian religion upholds Jesus of Nazereth as a "moral example" and his was an example of compasssion for those that didn't "fit". America is great because it is a land of opportunity where all men have inalienable rights to pursue their goals.
Montesquieu was not a "Christian", but was a political philosopher that had a great impact on America's Founding.
"I have examined all religions, as well as my narrow sphere, my straightened means, and my busy life, would allow; and the result is that the Bible is the best Book in the world. It contains more philosophy than all the libraries I have seen."
~John Adams to Thomas Jefferson, December 25, 1813.
Christian education should not be about Scripture as an inerrant, infallible "Word of God", but as a philosophy of human nature. The law is the equalizer among men, as the law protects human nature from itself. Human nature is prone to err, as it is limited in scope, self-interested, and opinionated by one's "culture". Scientists understand "human nature" as "survival of the fittest".
Virtue is a defense for civility. Without virtue, civilization would be lost on war, revenge, and spitefulness. Self interest is not bad, it just is. This is why we need to acknowledge and identify what our self interest is about and negotiate our differences. This is where social contract can protect peace and uphold justice.
Without an understanding of human nature, which scientists still are investigating, the world cannot live in peace.
