'Scoundrel!', scoffed minister (6)
I believe the answer is:
curate
'minister' is the definition.
('curate' can be a synonym of 'minister')
'scoundrel scoffed' is the wordplay.
'scoundrel' becomes 'cur' (I've seen this before**).
'scoffed' becomes 'ate' ('to scoff' is to eat).
'cur'+'ate'='CURATE'
(Other definitions for curate that I've seen before include "assistant rector" , "Clergyman assisting priest" , "A truce (anag)" , "Priest, a vicar's assistant" , "Junior priest in a parish" .)
