Father Rory embodies sin (5)
I believe the answer is:
error
'sin' is the definition.
(I've seen this in another clue)
'father rory embodies' is the wordplay.
'embodies' indicates a hidden word.
'ERROR' is hidden in the letters of 'father rory'.
(Other definitions for error that I've seen before include "Way of operating" , "Blunder, slip" , "Blunder or mistake" , "Howler" , "Faulty judgement" .)
