Pathway to the altar (5)
I believe the answer is:
aisle
'pathway to the altar' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for aisle that I've seen before include "Supermarket feature" , "way for prospective union members?" , "Supermarket section" , "Passage between pews" , "way to the altar?" .)
