Surly fellow took in cleric (6)
I believe the answer is:
curate
'cleric' is the definition.
(I've seen this before)
'surly fellow took' is the wordplay.
'surly fellow' becomes 'cur' (I've seen this in another clue).
'took' becomes 'ate' (eating is a kind of taking).
'cur'+'ate'='CURATE'
'in' is the link.
(Other definitions for curate that I've seen before include "Churchman" , "Junior priest in a parish" , "one wearing dog-collar" , "A truce for the church minister" , "Junior church minister" .)
