cardinal points

I'm a little stuck... Click here to teach me more about this clue!

'north and south say' is the definition.
I can't judge whether this definition defines the answer.

'church chief indicates' is the wordplay.
'church chief' becomes 'cardinal' (I can't explain this - if you can you should give a lot more credence to this answer).
'indicates' becomes 'points' ('point' can be a synonym of 'indicate').
'cardinal'+'points'='CARDINAL POINTS'

Can you help me to learn more?

(Other definitions for cardinal points that I've seen before include "major directions" , "key directions" .)
