Spirit-raising meeting tackling Bible – ring bishop to start ceremony (10)
I believe the answer is:
observance
'ceremony' is the definition.
(I know that ceremony can be written as observance)
'spirit-raising meeting tackling bible ring bishop to start' is the wordplay.
'spirit-raising meeting' becomes 'seance' (I've seen this in another clue).
'tackling' is an insertion indicator (to tackle is to take possession of).
'bible' becomes 'rv' (Revised Version, revision of King James Bible).
'ring bishop' becomes 'ob' (I can't justify this - if you can you should believe this answer much more).
'to start' means one lot of letters go next to another.
'seance' enclosing 'rv' is 'servance'.
'servance' put after 'ob' is 'OBSERVANCE'.
Can you help me to learn more?
(Other definitions for observance that I've seen before include "... than in the ____' (said 4)" , "ritual" , "As a rule" .)
