Stir men in church (7)

I believe the answer is:

minster

I'm a little stuck... Click here to teach me more about this clue!

'church' is the definition.
(I know that minster is a type of cathedral)

'stir men' is the wordplay.
'stir men' can be anagrammed to 'MINSTER'.
Though, I am not sure how this is indicated.

'in' acts as a link.

Can you help me to learn more?

(Other definitions for minster that I've seen before include "Clergyman" , "Old monastic cathedral, such as York's" , "Large church (or cathedral at York)" , "Abbey or priory church" , "Large church (eg, York)" .)

I've seen this clue in The Irish Independent.
