'getting cross belonging to church with new hymn' is the definition.
I can't judge whether this definition defines the answer.

'belonging to church with new hymn' is the wordplay.
'belonging to' becomes 'in' (I've seen this in other clues).
'church' becomes 'CE' (abbreviation for Church of England).
'with' says to put letters next to each other.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'hymn' becomes 'sing' (I've seen this in other clues).
'in'+'ce'+'n'+'sing'='INCENSING'

Can you help me to learn more?
