Church council looking into heresy, no doubt (5)
I believe the answer is:
synod
'church council' is the definition.
(type of church assembly)
'into heresy no doubt' is the wordplay.
'into' says the answer is hidden in the clue.
'SYNOD' is hidden within 'heresy no doubt'.
'looking' acts as a link.
This may not be right. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for synod that I've seen before include "Clerical assembly" , "Ecclesiastical assembly" , "group of clergymen" , "Ecumenical council" , "Assembly of the clergy" .)
