Church worker attacked carrying cross (6)
I believe the answer is:
sexton
'church worker' is the definition.
(I've seen this before)
'attacked carrying cross' is the wordplay.
'attacked' becomes 'seton' (I've seen this in other clues).
'carrying' indicates putting letters inside.
'cross' becomes 'x'.
'seton' going around 'x' is 'SEXTON'.
(Other definitions for sexton that I've seen before include "Church functionary" , "Church worker" , "Church employee" , "Sacristan" , "One might dig" .)
