Absolve yourself from plan embracing overthrow of Church (6)
I believe the answer is:
recuse
'absolve yourself' is the definition.
I can't judge whether this defines the answer.
'plan embracing overthrow of church' is the wordplay.
'plan' becomes 'ruse' (I have seen 'Cunning plan' mean 'ruse' so perhaps 'plan' could also mean 'ruse').
'embracing' is an insertion indicator.
'overthrow of' shows that the letters should be reversed in order (I've seen 'overthrows' mean this).
'church' becomes 'CE' (Church of England).
'ce' backwards is 'ec'.
'ruse' going around 'ec' is 'RECUSE'.
'from' acts as a link.
Can you help me to learn more?
(Another definition for recuse that I've seen is " Disqualify oneself as a judge in a case".)
