Performs part of the bible (4)
I believe the answer is:
acts
I believe this is a double definition.
'performs' is the first definition.
(acting is a kind of performing)
'part of the bible' is the second definition.
('Acts' is part of 'bible')
(Other definitions for acts that I've seen before include "Cast in major play sections" , "Cast in exploits" , "exerts influence" , "[BOOK] of the 26 [BIBLE]" , "Dramatic parts" .)
