Appeals for weapons to be given to church (6)
I believe the answer is:
charms
'appeals' is the definition.
('charm' can be a synonym of 'appeal')
'weapons to be given to church' is the wordplay.
'weapons' becomes 'arms' ('arm' can be a synonym of 'weapon').
'to be given to' means one lot of letters go next to another.
'church' becomes 'ch' (common abbreviation).
'arms' after 'ch' is 'CHARMS'.
'for' is the link.
(Other definitions for charms that I've seen before include "Delights" , "Enchants" , "Congreve 'Music has ..... to soothe a savage breast'" , "''Music hath . . . . . . to soothe a savage breast''" , "Attracts with bracelet ornaments" .)
