Hypocritical, I note, following religious education (9)
I believe the answer is:
insincere
'hypocritical' is the definition.
(synonyms)
'i note following religious education' is the wordplay.
'note' becomes 'n' (abbreviation).
'following' becomes 'since' (since can mean following or after).
'religious education' becomes 'RE' (abbreviation).
'i'+'n'+'since'+'re'='INSINCERE'
(Other definitions for insincere that I've seen before include "Not genuine, feigned" , "Hollow" , "Dishonest" , "fake" , "Deceitful, not genuine" .)
