Pagan deity priest continually repelled (5)
I believe the answer is:
freya
'pagan deity' is the definition.
(Norse god)
'priest continually repelled' is the wordplay.
'priest' becomes 'fr' (abbreviation for father).
'continually' becomes 'aye' (Scottish term meaning always).
'repelled' says the letters should be written backwards.
'aye' in reverse letter order is 'eya'.
'fr'+'eya'='FREYA'
(Other definitions for freya that I've seen before include "Norwegian goddess" , "Norse love goddess" , "Female" .)
