Tree for church official (5)
I believe the answer is:
elder
This clue is a double definition.
'tree' is the first definition.
(elder is a kind of tree)
'church official' is the second definition.
(as in church elders)
'for' acts as a link.
(Other definitions for elder that I've seen before include "Tribal leader; tree" , "Senior churchman - shrub" , "Official of some Churches, or senior statesman" , "Berry-bearing shrub" , "more mature" .)
