Cathedral cleric, second one ousted (7)
I believe the answer is:
minster
'cathedral' is the definition.
(minster is a kind of cathedral)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for minster that I've seen before include "Large church (or cathedral at York)" , "Clergyman" , "Abbey or priory church" , "Old monastic cathedral, such as York's" , "Large church (eg, York)" .)
