Construction worker with church official (6)
I believe the answer is:
welder
'construction worker' is the definition.
(I've seen this in another clue)
'with church official' is the wordplay.
'with' becomes 'w' (short for with).
'church official' becomes 'elder' (as in church elders).
'w'+'elder'='WELDER'
(Other definitions for welder that I've seen before include "Skilled worker who fuses metals using heat" , "Torch-bearer" , "Joiner of metals" , "Metal joiner" , "metalworker" .)
