Roman Catholic Diocese of Larino
[5] In 493/494, Pope Gelasius I granted Bishop Justus permission to consecrate a basilica in honor of the Archangel Michael, which had been built in his diocese by Priscillianus and Felicissima.
His alleged remains were not brought to Larino until the 9th or 10th century[7] On 11 November 943, Pope Marinus II granted a privilege to Bishop Joannes of Benevento, which included "whatever your predecessors were seen to possess legally and reasonably by ancient law," including: "Bivinem, Asculum, Larinum, Sipontum et ecclesiam s. Michaelis archangeli in Monte Gargano cum omnibus earum pertinentiis et omnia praedia.
[9] On 26 May 969, Pope John XIII raised Benevento to the rank of archdiocese, granted its bishop Landolfus the title of archbishop with the pallium, and the right to consecrate bishops in his territory: "facultatemque consecrandi episcopos in locis, quibus olim fuerant, scilicet Sancta Agathe, Abellino, Quintodecimo, Ariano, Asculo, Bibinae, Vulturaria, Larino, Thelesia, Alifis.
Perronius was ordered to present himself at the papal court, which was living in exile in Perugia, and explain his conduct to Martin IV face-to-face.
He then left the court, without permission, and returned to Larino, where he continued his activities against the heirs of King Charles and the papacy, engaging in sedition and conspiracy.
Pope Honorius IV (1285–1287) ordered the archbishop of Benevento, on 4 April 1285, to cite Bishop Perronius to the papal court within thirty days.
[15] in a letter of 6 August 1289, Pope Nicholas IV had given Cardinal Berardus, his legate in Sicily, the mandate of finding a suitable place for Bishop Saba.
[16] Cardinal Berardus appointed Bishop Saba as administrator of the diocese of Larino, which was regarded as a vacant see, on a temporary basis (usque ad suum beneplacitum).
[19] After his death, Pope Boniface VIII granted the administratorship of the diocese of Larino to Archbishop Joannes d'Alatri of Benevento, on 8 May 1299.
On 11 April 1301, however, Pope Boniface decided to appoint the rehabilitated bishop of Fiesole, Angelo, his apostolic administrator of Larino, pastore vacantis.
[24] On 22 February (or 8 March) 1304, Pope Benedict XI appointed Pasquale,[25] one time bishop of Cassano, apostolic administrator of the diocese of Larino, on a temporary basis (usque ad Apostolicae Sedis beneplacitum).
They chose to proceed by the way of compromise, and appointed a committee composed of Archpriest Garinus and the canons Hugo Roberti, and Luca Magni Petri.
On 21 August 1976, he issued the decree "Ad apicem", creating the new ecclesiastical province entitled «Boianensis-Campobassensis», with its administrative center in Campobasso.
Based on the revisions, a set of Normae was issued on 15 November 1984, which was accompanied in the next year, on 3 June 1985, by enabling legislation.
According to the agreement, the practice of having one bishop govern two separate dioceses at the same time, aeque personaliter, was abolished.
