Last characters in church to feel godly or saintly (4)
I believe the answer is:
holy
'saintly' is the definition.
(both can mean religious)
'last characters in church to feel godly' is the wordplay.
'last characters in' says to take the final letters.
The final letters of 'church to feel godly' are 'HOLY'.
'or' is the link.
(Other definitions for holy that I've seen before include "Dedicated to God" , "Sacred" , "Charlemagne was the first" , "Sanctified" , "Hallowed" .)
