Service his curate arranged (9)
I believe the answer is:
eucharist
'service' is the definition.
(I've seen this before)
'his curate arranged' is the wordplay.
'arranged' indicates anagramming the letters.
'his'+'curate'='hiscurate'
'hiscurate' anagrammed gives 'EUCHARIST'.
(Other definitions for eucharist that I've seen before include "host" , "church service" , "Holy Communion" , "Bread and wine" , "Consecrated bread" .)
