It sure rattles carrying tea service! (9)
I believe the answer is:
eucharist
'service' is the definition.
(I've seen this before)
'it sure rattles carrying tea' is the wordplay.
'rattles' indicates anagramming the letters.
'carrying' is an insertion indicator.
'tea' becomes 'cha' (cha is a type of tea).
'it'+'sure'='itsure'
'itsure' anagrammed gives 'eurist'.
'eurist' going around 'cha' is 'EUCHARIST'.
(Other definitions for eucharist that I've seen before include "host" , "church service" , "Holy Communion" , "Mass" , "Consecrated bread" .)
