What is the difference between prudent behaviour and 'moral' behaviour?

A Christian fundamentalist who observes the proprieties and helps his neighbor only from fear of 
I will got to hell if I dont behave in this 'moral' wayhellfire is manifesting prudence rather than moral values.

 Similarly for the man with felony in his heart who behaves himself for fear of the law is similarly
behaving prudently.

What does one extrapolate from this:beware of those who  berate you with their 'moral' grandstanding.

morals = equal coherence theory (it makes sense or it is how we have been taught, we have been inducted into these 'moral' thought patterns)

Moral valuation have "no analog" with questions of scientific facts (assignment of truth values to statements about the world). Thus, in the end, moral judgment can be nothing but a reflection of what we have been taught to believe or what is inherent in us based on natural selection. Quine is paraphrased here, by one of his interlocutors, as saying the best that you can get in moral valuation are claims reflecting a kind of coherence theory, while in science you can get statements according to a kind of correspondence theory
