Sybil's husband in charge of church with ceremonial rights … (7)

I believe the answer is:

basilic

'church with ceremonial rights' is the definition.
(alternative term for basilica)

'sybil's husband in charge' is the wordplay.
'sybil's husband' becomes 'basil' (ref to Basil and Sybil Fawlty from Fawlty Towers).
'in charge' becomes 'ic'.
'basil'+'ic'='BASILIC'

'of' is the link.

I've seen this clue in The Guardian.
