Seeing that immoral act, committed by church? (5)
I believe the answer is:
since
'seeing that' is the definition.
('seeing that' means 'since' or 'because')
'immoral act committed by church?' is the wordplay.
I cannot really understand how this works, but
'act' could be 'sin' (sin is a kind of act) and 'sin' is present in the answer.
'church?' could be 'ce' (Church of England) and 'ce' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for since that I've seen before include "Seeing that" , "in the past" , "From that time one" , "Because; ago" .)
