The Prudent Use of the Law: Does a Culture of Dignity Flow from Decency?

"Human dignity is more than the right to be left alone."  What are the limitations of Libertarianism for Christians?   Does a decent society require a religious foundation?  Surely there are atheists who are kind, but as a society, there needs to be a moral culture that gives definition for freedom.  Freedom is not the same as autonomy.  Freedom is the ability to do the good.  But who is to say what is good without a revelation that comes from a higher authority than man himself?  Perhaps government and law cannot make us good, but isn't every sin destructive to society?  So shouldn't every sin be legislated?  Hodges and Vowell speculate on how to address the law.
