Decreed (8)
I believe the answer is:
ordained
'decreed' is the definition.
(I know that decreed can be written as ordained)
This is the entire clue.
(Other definitions for ordained that I've seen before include "Declared to be law or declared to be a priest" , "Laid down the law" , "Decreed, or appointed to priesthood" , "Elevated to the priesthood" , "Appointed to a clerical post" .)
