Doctrine at odds with religious beliefs, shame it unravelled (7)
I believe the answer is:
atheism
'doctrine at odds with religious beliefs' is the definition.
I can't judge whether this defines the answer.
'shame it unravelled' is the wordplay.
'unravelled' is an anagram indicator.
'shame'+'it'='shameit'
'shameit' anagrammed gives 'ATHEISM'.
Can you help me to learn more?
(Other definitions for atheism that I've seen before include "A lack of faith" , "Disbelief in a god" , "Lack of belief in the existence of God" , "displaying opposition to religion" , "Disbelief in gods" .)
