Cleric finished with gold (6)
I believe the answer is:
pastor
'cleric' is the definition.
(thesaurus)
'finished with gold' is the wordplay.
'finished' becomes 'past'.
'with' says to put letters next to each other.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'past'+'or'='PASTOR'
(Other definitions for pastor that I've seen before include "To spar with clergyman" , "Christian minister" , "Padre perhaps" , "Old shepherd" , "Minister; shepherd" .)
