A padre organised procession (6)
I believe the answer is:
parade
'procession' is the definition.
(parade is a kind of procession)
'a padre organised' is the wordplay.
'organised' indicates an anagram.
'a'+'padre'='apadre'
'apadre' is an anagram of 'PARADE'.
(Other definitions for parade that I've seen before include "Public procession or ceremonial march" , "Cavalcade or procession" , "Exhibit" , "Flaunt; ceremonial march" , "Row of shops, march" .)
