The Diocese of Acerno was a Roman Catholic diocese based in Acerno, a distance of 68 km (42 mi.) from Naples in southern Italy, with the bishop's seat in Acerno Cathedral. Created in the 11th century, in 1818, the diocese was granted in perpetual administratorship to the archbishops of Salerno. In the reorganization of ecclesiastical provinces in 1986, Acerno was suppressed, to create the Archdiocese of Salerno-Campagna-Acerno.
History
The cathedral of Acerno was originally dedicated in honor of S. Peter, but, like nearly all the cathedrals in the kingdom of Naples, came to be dedicated as well to the Virgin Mary, in this case under the title of the Annunciation. The cathedral was administered by a Chapter, which was led by four dignities, the Archdeacon, the Primicerius, the Treasurer, and the Cantor; the office of Cantor later disappeared. The original number of canons is uncertain, but by 1792 they numbered eighteen.
Bishop Giovanni Serrano, O.F.M.Observ., held a diocesan synod in Acerno in 1626, announcing at the Vatican during his ad limina visit in 1626 that he did not contemplate holding another.
In 1792, the town of Acerno had a population of around 2,000 people. In the town was one religious house of men, the Conventual Franciscans. The bishop preferred to reside in Monte Corvino, some 19 km to the southwest. In the town of Picenzia, an area of some 600 families, there was a collegiate church dedicated to S. Peter, which was headed by an Archpriest, a Primicerius, and a Treasurer, with two chaplains.
In May 1805, Napoleon had himself crowned King of Italy. After the Battle of Austerlitz on 2 December, a French army was sent to occupy the kingdom of Naples. On 23 January 1806, Ferdinand IV fled to Sicily, and on 14 February the French occupied Naples. Napoleon's brother, Joseph Bonaparte, was declared king on 30 March 1806, and after he was transferred to Spain, General Joachim Murat was declared King of Naples on 1 August 1808. In 1809, France annexed the Papal States, and Pope Pius VII was deported. Under such conditions, neither nomination to vacant dioceses by the king, nor confirmation by the pope, took place.
After Napoleon
Following the extinction of the Napoleonic Kingdom of Italy, the Congress of Vienna authorized the restoration of the Papal States and the Kingdom of Naples. Since the French occupation had seen the abolition of many Church institutions in the Kingdom, as well as the confiscation of most Church property and resources, it was imperative that Pope Pius VII and King Ferdinand IV reach agreement on restoration and restitution.
A concordat was finally signed on 16 February 1818, and ratified by Pius VII on 25 February 1818. Ferdinand issued the concordat as a law on 21 March 1818. The re-erection of the dioceses of the kingdom and the ecclesiastical provinces took more than three years. The right of the king to nominate the candidate for a vacant bishopric was recognized, as in the Concordat of 1741, subject to papal confirmation (preconisation). On 27 June 1818, Pius VII issued the bull De Ulteriore, in which he reestablished the metropolitan archbishopric of Salerno, with five suffragan dioceses, the diocese of Capaccio e Vallo, diocese of Policastro, diocese of Potenza e Marsico Nuovo, and diocese of Nusco.
The See of Acerno was granted to the archbishop of Salerno as its perpetual administrator. In 1920, the diocese of Acerno had seven parishes, seven churches, and sixteen secular priests.
On 4 August 1973, the Archbishop of Salerno and Perpetual Administrator of the diocese of Acerno, Gaetano Pollio (1969-1984) was also named bishop of Campagna, thereby serving as bishop of three dioceses at one and the same time, aeque personaliter.
Diocesan reorganization
The Second Vatican Council (1962–1965), 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. It also recommended the abolition of anomalous units such as exempt territorial prelatures.
