'historical ignorance' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'in church around since reformation' is the wordplay.
'church' becomes 'ce' (Church of England).
'around' indicates putting letters inside.
'reformation' is an anagram indicator.
'in'+'ce'='ince'
'since' is an anagram of 'nscie'.
'ince' going around 'nscie' is 'INSCIENCE'.
