Allegiance founded around verse of the gospels (11)
I believe the answer is:
evangelical
'allegiance founded' is the definition.
I can't tell whether this definition defines the answer.
'around verse of the gospels' is the wordplay.
'around' is an insertion indicator.
'verse of' becomes 'lica' (I am not sure about this - if you are sure you should believe this answer much more).
'the gospels' becomes 'evangel' ('evangel' can be a synonym of 'gospels').
'lica' put inside 'evangel' is 'EVANGELICAL'.
Can you help me to learn more?
(Other definitions for evangelical that I've seen before include "Fervent in advocacy" , "Crusading" , "Zealous" , "Fervent in advocating something" , "church member" .)
