Heavenly church tallies, somehow (9)
I believe the answer is:
celestial
'heavenly' is the definition.
('celestial' can be a synonym of 'heavenly')
'church tallies somehow' is the wordplay.
'church' becomes 'ce' (abbreviation for Church of England).
'somehow' is an anagram indicator.
'tallies' with letters rearranged gives 'lestial'.
'ce'+'lestial'='CELESTIAL'
(Other definitions for celestial that I've seen before include "Relating to the heavens" , "Heavenly" .)
