Church members? They may be lucky (6)
I believe the answer is:
charms
'they may be lucky' is the definition.
The definition suggests an adverb but the answer is not.
'church members?' is the wordplay.
'church' becomes 'ch' (abbreviation on maps etc).
'members?' becomes 'arms' (arm is a kind of member).
'ch'+'arms'='CHARMS'
Can you help me to learn more?
(Other definitions for charms that I've seen before include "Small ornaments worn on chain or bracelet" , "Enchants" , "Congreve 'Music has ..... to soothe a savage breast'" , "Beguiles with trinkets" , "Attracts with bracelet ornaments" .)
