Friends collecting a sum for the church (5)
I believe the answer is:
chums
'friends' is the definition.
(chum is a kind of friend)
'collecting a sum for the church' is the wordplay.
'collecting a sum' becomes 'ums' (I am not sure about this - if you are sure you should believe this answer much more).
'for' says to put letters next to each other (I've seen this in other clues).
'the church' becomes 'ch' (common abbreviation).
'ums' put after 'ch' is 'CHUMS'.
Can you help me to learn more?
