Church always provides festive food and drink (5)
I believe the answer is:
cheer
'festive food and drink' is the definition.
(I've seen this before)
'church always' is the wordplay.
'church' becomes 'ch' (common abbreviation).
'always' becomes 'eer' (poetic way of saying ever).
'ch'+'eer'='CHEER'
'provides' is the link.
(Other definitions for cheer that I've seen before include "Inspirit" , "Give comfort or support to" , "Shout applause and support" , "Shout of encouragement" , "party refreshment?" .)
