It is funny what I read in the net sometimes. It is a well known fact, that Calvinism created a moralist society in the South of the United States, and around the world. This fact, was even mentioned in the short course on Calvinism held by the University of Geneva, in which even the guest American lecturer, pointed to that fact.
R. Scott Clark has written about this subject, pointing out that the NPP is a clear example of moralism. You can look at it here.
This is a great reversal, coming from someone who comes from a very moralist type of Reformed faith. If you don’t believe me, look at the Puritans.
