III. The rights of the metropolitans under the vicariate of Anastasius are to be observed.
Therefore according to the canons of the holy Fathers, which are framed by the spirit of God and hollowed by the whole world's reverence, we decree that the metropolitan bishops of each province over which your care, brother, extends by our delegacy, shall keep untouched the rights of their position which have been handed down to them from olden times: but on condition that they do not depart from the existing regulations by any carelessness or arrogance.
