Compass of ecumenic furore regularly disrupted church (13)
I believe the answer is:
circumference
'compass' is the definition.
(thesaurus)
'ecumenic furore regularly disrupted church' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'disrupted' indicates anagramming the letters.
'church' becomes 'CE' (Church of England).
The alternate letters of 'furore' are 'frr'.
'ecumenic'+'frr'='ecumenicfrr'
'ecumenicfrr' with letters rearranged gives 'circumferen'.
'circumferen'+'ce'='CIRCUMFERENCE'
'of' acts as a link.
(Other definitions for circumference that I've seen before include "Boundary of a circle" , "Distance around circle" , "Exterior of circle" , "Earth's is circa twenty-five thousand miles" , "Perimeter of circle" .)
