There were great advantages and yet great disadvantages to "Christendom." The advantage was that there was a common language for public moral discourse with which society could discuss what was "the good." The disadvantage was that Christian morality without gospel-changed hearts often led to cruelty and hypocrisy. Think of how the small town in "Christendom" treated the unwed mother or the gay person.
