Horse belonging to fruity girl in a gospel scene (5,2,6)

'a gospel scene' is the definition.
(location in the Christian Gospels)

'horse belonging to fruity girl' is the wordplay.
I cannot quite understand how this works, but
'horse' could be 'mount' (mount is a kind of horse) and 'mount' is found in the answer.
'girl' could be 'olive' and 'olive' is found in the answer.
'belonging to' could be 'of' ('of' can mean 'belonging to' or 'owned by') and 'of' is found in the answer.
A single letter 's' remains which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).

'in' acts as a link.
