Hell, with a group of religious folk creating chaos (8)
I believe the answer is:
disorder
'chaos' is the definition.
(I've seen this before)
'hell with a group of religious folk' is the wordplay.
'hell' becomes 'dis' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'a group of religious folk' becomes 'order' (eg an order of monks).
'dis'+'order'='DISORDER'
'creating' acts as a link.
(Other definitions for disorder that I've seen before include "breach of the peace" , "[MAYHEM] ?" , "Commotion" , "Confused state" , "Although it's only a minor ailment" .)
