The Diocese of Terni-Narni-Amelia (Latin: Dioecesis Interamnensis-Narniensis-Amerina) is a Latin Church ecclesiastical territory or diocese of the Catholic Church in Umbria, central Italy. It was created in 1983, when the Diocese of Amelia was united with the Diocese of Terni and Narni. The latter had been in turn created in 1907, when the Diocese of Narni was united to the historical Diocese of Terni.[1] [2] The diocese is immediately exempt to the Holy See, not part of any ecclesiastical province.
Terni is the ancient Interamna Nahars of the Umbrians, and the cathedral, and other churches, are built on the sites of pagan temples. After the Lombard invasion, Terni belonged to the Duchy of Spoleto, and with the latter, came into the Pontifical States. It was at Terni that Pope Zacharias entered into the agreement with King Luitprand for the restitution of the cities of Bieda, Orte, Bomarzo, and Amelia to the Duchy of Rome.
It is believed that the gospel was preached at Terni by Peregrinus, about the middle of the second century. Saint Valentinus has a basilica outside the city. There were other martyrs from this city, among them saints Proculus, Ephebus, Apollonius, and the holy virgin Agape.
In the time of Totila, the Bishop of Terni, Proculus of Terni, was killed at Bologna, and Domnina of Terni and ten nuns, her companions, were put to death at Terni itself. After the eighth century Terni was without a bishop until 1217, in which year the diocese was re-established.
