Loud day of religious rejoicing — no hesitation to provide a banquet (5)
I believe the answer is:
feast
'a banquet' is the definition.
(I know that banquet can be written as feast)
'loud day of religious rejoicing no hesitation' is the wordplay.
'loud' becomes 'f' (short for forte - 'loud' in music).
'day of religious rejoicing' becomes 'Easter' (religious festival).
'no' indicates named letters should be taken away.
'hesitation' becomes 'er' (sound used when hesitating).
'easter' with 'er' taken away is 'east'.
'f'+'east'='FEAST'
'to provide' is the link.
(Other definitions for feast that I've seen before include "wine and dine" , "Big meal" , "Huge nosh-up" , "Repast" , "Celebration" .)
