Worshippers finally addressed God and dispersed (7)
I believe the answer is:
sprayed
'dispersed' is the definition.
(spraying is a kind of dispersing)
'worshippers finally addressed god' is the wordplay.
'finally' indicates one should take the final letters.
'addressed god' becomes 'prayed' (to pray is to address God).
The final letter of 'worshippers' is 's'.
's'+'prayed'='SPRAYED'
'and' acts as a link.
(Other definitions for sprayed that I've seen before include "showered" , "Sprinkled" , "Sent out liquid in very small drops" .)
