The Roman Catholic diocese of Ferentino existed until 1986, when it was united into the new diocese of Frosinone-Veroli-Ferentino.
History
It is said, by Ferdinand Ughelli, that in the time of Emperor Constantine, in the 1st third of the fourth century, Ferentino had its own bishop; but the first bishop known by name is Bassus, at the end of the 5th century. Bishop Redemptus (about 570) is mentioned in the Dialogues of Gregory the Great, but Redemptus was bishop of Ferentum in Tuscany, not Ferentinum in Latium. Pope Gregory also refers to a Bishop Boniface, but he was a bishop of Ferentum in Tuscany.
Diocesan reorganization
The Second Vatican Council, in order to ensure that all Catholics received proper spiritual attention, decreed the reorganization of the diocesan structure of Italy and the consolidation of small and struggling dioceses, in particular those with financial and personnel problems. It also decreed that the natural population units of people, together with the civil jurisdictions and social institutions that compose their organic structure, should be preserved as far as possible as units.
On 18 February 1984, the Vatican and the Italian State signed a new and revised concordat. 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. This applied to the dioceses of Veroli and Frosinone. The Vatican therefore continued consultations which had begun under Pope John XXIII for the merging of dioceses. On 30 September 1986, Pope John Paul II ordered that the dioceses of Veroli, Frosinone, and Ferentino be merged into one diocese with one bishop, with the Latin title Dioecesis Frusinatensis-Verulana-Ferentina. The seat of the diocese was to be in Frosinone, whose cathedral was to serve as the cathedral of the merged dioceses. The cathedrals in Veroli and Ferentino were to become co-cathedrals, and the cathedral Chapters were each to be a Capitulum Concathedralis. There was to be only one diocesan Tribunal, in Frosinone, and likewise one seminary, one College of Consultors, and one Priests' Council. The territory of the new diocese was to include the territory of the former dioceses of Veroli, Frosinone, and Ferentino.
