Tell Church is uplifted in ceremony (6)
I believe the answer is:
recite
'tell' is the definition.
('recite' can be a synonym of 'tell')
'church is uplifted in ceremony' is the wordplay.
'church' becomes 'ce' (abbreviation for Church of England).
'is uplifted' shows that the letters should be reversed in order.
'in' is an insertion indicator.
'ceremony' becomes 'rite' (rite is a kind of ceremony).
'ce' in reverse letter order is 'ec'.
'ec' put inside 'rite' is 'RECITE'.
(Other definitions for recite that I've seen before include "Declaim, recount" , "Speak (poem) aloud" , "Intone" , "deliver lines that have been recalled" , "Repeat aloud from memory, say poetry" .)
