Working with the church modus operandi -- religious education again (4,4)

I believe the answer is:

once more

'again' is the definition.
(synonyms)

'working with the church modus operandi religious education' is the wordplay.
'working' becomes 'on'.
'with' is a charade indicator (letters next to each other).
'the church' becomes 'ce' (abbreviation for Church of England).
'modus operandi' becomes 'mo' (common abbreviation).
'religious education' becomes 're'.
'on'+'ce'+'mo'+'re'='ONCE MORE'

(Another definition for once more that I've seen is " Again".)

I've seen this clue in The Telegraph.
