Outspoken bit in Anglican didacticism (6)
I believe the answer is:
candid
'outspoken' is the definition.
(I know that outspoken can be written as candid)
'bit in anglican didacticism' is the wordplay.
'bit' says the answer is hidden in the clue (I've seen 'bit of' mean this).
'CANDID' can be found hidden inside 'in anglican didacticism'.
(Other definitions for candid that I've seen before include "Frank - open" , "Open and truthful" , "Frank - unbiased" , "'Forthright, open (6)'" , "Frank, forthright" .)
