Hold first woman trailing bishop and priest (7)
I believe the answer is:
believe
'hold' is the definition.
(believing is a kind of holding)
'first woman trailing bishop and priest' is the wordplay.
'first woman' becomes 'eve' (I've seen this before).
'trailing' is a charade indicator (letters next to each other).
'bishop' becomes 'b' (abbreviation used in chess).
'and' says to put letters next to each other.
'priest' becomes 'eli' (I've seen this before).
'b'+'eli'='beli'
'eve' put after 'beli' is 'BELIEVE'.
(Other definitions for believe that I've seen before include "Have religious faith" , "Think" , "Regard as true" , "Have faith; understand" , "Swallow" .)
