Bishop with no more to consecrate (5)
I believe the answer is:
bless
'consecrate' is the definition.
('bless' can be a synonym of 'consecrate')
'bishop with no more' is the wordplay.
'bishop' becomes 'b' (abbreviation used in chess).
'with' is a charade indicator (letters next to each other).
'no more' becomes 'less' (I've seen this in other clues).
'b'+'less'='BLESS'
'to' is the link.
(Other definitions for bless that I've seen before include "Glorify" , "Sanctify" , "Give benediction" , "Call on God to favour" , "Endow; praise" .)
