In my opinion, even the best of churches have forgotten their part in making America. They actually believe that there’s some kind of constitutional restriction on political speech from the pulpit and can’t even consider the possibility that they themselves planted the seeds of the American revolution.
This country only works if people have a basic sense of morality. I would argue that all moral authority comes from a power greater than Man. I would conclude that the Church’s reluctance to exert influence in the public square is a major reason our society is in decline.
