Unquestionable doctrine (5)

Ross

I believe the answer is:

dogma

(Other definitions for dogma that I've seen before include "Principles laid down by authority as true" , "Incontrovertible set of principles" , "Item of belief" , "Inflexible principles" , "Religious doctrine proclaimed as true without proof" .)

I've seen this clue in the Wall Street Journal and The Guardian.
