You try to impose silence on us by the authority of Gelasius, by the same authority we close your mouth:

Nulla presumptione statum parrochiarum qui perpetue etatis firmitate durauit, patimur immutari, quia nec negligentia pontificum, nec temporalis obiectio, que per incuriam forte generatur, neque ignauia faciente consensus adhibitus, nec subripiente supplicatione preceptio diuellere potest semel diocesim constitutam.

<Gratianus> § Set qualiter hec distinguantur auctoritates in causa monachorum inuenietur <C.17 q.3>
