Strict moralist (7)

Ross

I believe the answer is:

puritan

(Other definitions for puritan that I've seen before include "Dour Protestant" , "Strait-laced" , "Moralistic type" , "Person of extreme moral strictness" , "Train up (anag.)" .)

I've seen this clue in the Newsday and the King Feature Syndicate.
