I believe that when Conservativism was being formulated as a political philosophy by Burke and others, some of the early Conservatives were not Christians (or Jews). BUT they nevertheless recognized that the type of society they wanted needed to be predicated on the morality and values that could only be found within the Judeo-Christian tradition. Therefore, as good Conservatives, they embraced the moral foundations of the Faith, even though they had no faith themselves.
The people who embrace the view of the world as a random place are just inviting chaos and anarchy.
For the sake of your soul, you should have faith.
For the sake of a just society, you should at least act like you have faith.
Actually the whole equality of man idea was more from the enlightenment thinkers than Christianity. The enlightenment thinker were mostly deists. So were some of our most prominent founding fathers(Thomas Jefferson, Ben Franklin, etc.).
That’s not to say that the enlightenment thinkers weren’t influence by Christianity but I’ve always thought that saying America is a judao/Christian society doesn’t tell the whole truth. We are truly a Roman/Greco, Judeo/Christian, Enlightenment Society. Of course that doesn’t roll of the tongue as good.
