Benedictus III, papa (855–858)

Pope Benedict III writes to Vitalis, the patriarch of Grado, conferring upon him the pallium.

At the Synod of Rome, convened in order to settle the conflict between the patriarchs of Aquileia and Grado, Pope John XIX condemns Patriarch Poppo’s invasion of Grado, revokes his earlier privilege according to which he was given ecclesiastical jurisdiction over the “island of Grado”, and confirms the metropolitan status of the Patriarchate of Grado.

Following the Synod of Rome, convened to resolve the recently rekindled conflict between the patriarchs of Aquileia and Grado, Pope Benedict IX writes to Urso, the patriarch of Grado, informing him of the Synod’s decision to support the cause of his church against the Aquileian Patriarch Poppo, who had recently launched a second military invasion of Grado before his untimely death; the pope confirms the metropolitan status together with the ecclesiastical and secular jurisdictions of the Patriarchate of Grado, dubbed “New Aquileia” for the very first time in an authentic papal document.
