One bishop of Rome, like all associated with pride (7)
I believe the answer is:
leonine
'associated with pride' is the definition.
The answer and definition are different parts of speech. However, past participle verbs and adjectives occasionally mean the same thing.
'one bishop of rome like all' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'one' is 'eon' which is present in the answer.
The remaining letters 'line' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for leonine that I've seen before include "Like a big cat" , "Resembling a lion" , "verse" , "Resembling a big cat" , "Unusually courageous" .)
