The point of Russian orthodoxy? (5)
I believe the answer is:
north
'the point' is the definition.
(north is a kind of point)
'of russian orthodoxy?' is the wordplay.
'of' indicates the answer is hidden within the clue.
'NORTH' is hidden in the letters of 'russian orthodoxy'.
(Other definitions for north that I've seen before include "One of four bridge players" , "Compass bearing" , "PM 1770-82" , "Bridge position" , "Former PM" .)
