Saint even broke into two churches? Yes, that's risky (7)

'saint even broke' is the definition.
I can't judge whether this definition defines the answer.

'into two churches? yes that's risky' is the wordplay.
'two churches?' means two substitutions for 'church'.
'into' means one lot of letters goes inside another.
'church' becomes 'ch' (common abbreviation).
'church' becomes 'ce' (abbreviation for Church of England).
'yes' becomes 'y'.
'that's risky' becomes 'an' (I can't justify this - if you can you should believe this answer much more).
'ch'+'ce'+'y'='chcey'
'chcey' placed around 'an' is 'CHANCEY'.

Can you help me to learn more?
