How Are Law And Morality Related?

In the movie based on the novel "Bonfire of the Vanities" in an outburst in court, the Judge played by veteran actor Morgan Freeman explains Justice to the attendants at court. "Justice" he says "is the law, and the law is man's feeble attempt to define the principles of decency. Decency is not a con or a hustle or an angle, it's in your bones, it's what your grandmother thought you". This argument purports law to be closely related to morals or ethics. It is an argument held by Natural Law as well.  

In contemporary society, especially the West, secularism is paving the way for progressively outdating moral connotations in Law. Law under theories such as positivism argues that law be derived from existing customs and norms. There seems to be very little middle ground anymore with views being either completely radical or completely liberal.
