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

'enemies' is the definition.
('opponent' can be a synonym of 'enemy')

'old parish priest one notes regularly' is the wordplay.
'old parish priest' becomes 'opp' (this could be a standard abbreviation I've not previously seen).
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
The alternate letters of 'notes' are 'nts'.
'opp'+'one'+'nts'='OPPONENTS'

'makes' is the link.
