I believe the answer is:

right reverend

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

'back' is the definition.
Both the definition and answer are adjectives.
Perhaps there's a link between them I don't understand?

'churchman heard ceremony run non-stop with curtains at the' is the wordplay.
I cannot quite understand how this works, but
'churchman' could be 'rev' (abbreviation for Reverend) and 'rev' is found within the answer.
'run' could be 'r' (cricket abbreviation) and 'r' is present in the answer.
'stop' could be 'end' ('end' can be a synonym of 'stop') and 'end' is found in the answer.
an anagram of 'the' is 'hte' which is located in the remaining letters.
This explanation may well be incorrect...
