The Archdiocese of Potenza-Muro Lucano-Marsico Nuovo () is a Latin diocese of the Catholic Church in Basilicata, southern Italy.

The current archdiocese is the result of two mergers. The historical Diocese of Potenza was united with the Diocese of Marsico Nuovo in 1818 to form the Archdiocese of Potenza e Marsico Nuovo, which was elevated to an archdiocese in 1973 and made a metropolitan see in 1976. In 1986, the Diocese of Muro Lucano was merged into it to form the current archdiocese."Archdiocese of Potenza-Muro Lucano-Marsico Nuovo" Catholic-Hierarchy.org. David M. Cheney.

The Ecclesiastical Province of Potenza (Basilicata) is composed of Potenza and its five suffragan dioceses: the Archdiocese of Acerenza, the Archdiocese of Matera-Irsina, the Diocese of Melfi-Rapolla-Venosa, the Diocese of Tricarico, and the Diocese of Tursi-Lagonegro.

History The town claims that it was evangelized by Saint Peter; Saint Aruntius and his companions are said to have suffered martyrdom there under the Emperor Maximian. The legend has been destructively criticized by Francesco Lanzoni (1927).Lanzoni, pp. 285-286. Cf. Cappelletti XX (1866), pp. 467-468, on which the old Catholic Encyclopedia article is based.

The date of the establishment of the Diocese of Potenza (Potentinus) is not known. The earliest known bishop is Herculentius, who corresponded with Pope Gelasius I between 494 and 496.Kehr XI, p. 484 with nos. 1 and 2. Bishop Faustinus, who was legate in Africa c. 418–422, is claimed as a bishop of Potenza in Lucania, but was actually a bishop of Potenza in Picenum: Kehr, p. 483; cf. Cappelletti XX, p. 468.

An outstanding bishop was Gerardo della Porta (1099–1119), who was recognized as a saint, and to whom the cathedral is dedicated, along with the universal dedication to the Assumption throughout the kingdom of Naples. In 1221, Bishop Garsias limited the number of canons in the cathedral Chapter to twelve.Kamp, p. 796. In 1721, the Chapter was headed by three dignities (the Archdeacon, the Archpriest, and the Cantor) and nine canons.Ughelli VII, p. 133.

The town of Potenza was destroyed by the earthquake of 1273 (or 1278).Gaetano Moroni, Dizionario di erudizione storico-ecclesiastica, Vol. LIV (Venezia: Emiliana 1852), p. 316 col. 1. Mario Baratta, I terremoti d'Italia (Torino: Fratelli Bocca 1901), pp. 37, 798.

Potenza was destroyed by order of the Emperor Frederick II, and was rebuilt by Bishop Oberto, beginning in 1250, to be destroyed again under Charles of Anjou.Cappelletti XX, p. 467, 470.

The Cathedral, built by Bishop Oberto (attested 1250–1256),Cappelletti XX, p. 470. was restored by Giovanni Andrea Serra (1783–99), and Achille Caracciolo (1616).Catholic Encyclopedia article, Marsico Nuovo and Potenza Bishop Achille Caracciolo was also responsible for laying the cornerstone of a new seminary.D'Avino, p. 546, column 1.

In 1694, Potenza was involved in the earthquake of 8 September, which affected nearly the entire kingdom of Naples. Three hundred houses were completely destroyed, the rest suffered damage. The church of Santissima Trinità and the castello were heavily damaged. Four or five people were reported dead.Baratta, pp. 173-181, at 177. The seminary building also suffered severe damage. Bishop Agnello Rossi (1695–1707) began the reconstruction.D'Avino, p. 546, column 1.

Bishop Giovanni Andrea Serrao (1783–1799) of Potenza was assassinated on 24 February 1799.Ritzler and Seferin, Hierarchia catholica VI, p. 347, note 7. M.D.F.D. [i.e. D.

On 27 June 1818, the diocese of Potenza was united with Diocese of Marsico Nuovo to form Diocese of Potenza e Marsico Nuovo. Potenza was made a suffragan of the archdiocese of Acerenza, along with Anglona e Tursi, Tricarico, and Venosa. The diocese of Matera was suppressed and united with the archdiocese of Acerenza.Torelli, pp. 117-118, § 6.

In the earthquake of 1 February 1826, all of the public and private buildings were seriously damaged. Two or three old buildings collapsed completely. The palace of the royal Intendant, the episcopal palace, the monastery of the Riformati, and the civic hospital were reduced to a bad condition. The campanile of the cathedral lost its lead roof.Baratta, p. 353. In the earthquake of 16 December 1857, in Basilicata there were 9591 deaths, with 1411 reported wounded. In the city of Potenza alone, 22 died and 11 were injured. Aftershocks continued into the next year.Baratta, p. 429. According to Cappelletti, the city of Potenza was practically annihilated.Cappelletti XX, pp. 477-478: "...la città di Potenza fu poco men che annientata."

A diocesan synod was held in Potenza by Bishop Gaspare Cardoso, O.S.B. (1606 – 1615) on 2 April 1606.Constitutiones et decreta dioecesanae synodi Potentianae, ... editae die secundo aprilis 1606 (Romae: ex typographia Guillelmi Facciotti MDCVI). Bishop Pietro Ignazio Marolda held a diocesan synod in Potenza in 1834.Constitutiones synodales Potentinae sub excellentis et reverendis domino D. Petro Ignatio Marolda Congregationis SS. Redemptoris, sacrae theologiae doctore, et magistro equite commendatore regalis ordinis Francisci I. dei, et apostolicae sedis gratia episcopo marsicense, et potentino. Potenza: Typis Antonii Santanello, 1835.

Post-Vatican II changes On 11 February 1973, Pope Paul VI promoted the diocese of Potenza e Marsico Nuovo to the status of an archdiocese, and made it immediately subject to the papacy; it had been suffragan to the Archdiocese of Acerenza. The bishop was given the rank of archbishop, and granted the right to use the processional cross and the pallium. The College of Canons of the cathedral, as well, were given archdiocesan dignity and privileges.Acta Apostolicae Sedis 65 (Città del Vaticano 1973), pp. 131-133.

On 31 May 1973, by decree of the Congregation of Bishops of the papal curia, five parishes belonging to the Diocese of Campagna were transferred to the jurisdiction of the archdiocese of Potenza."Quo Aptius," Acta Apostolicae Sedis 65 (Città del Vaticano 1973), pp. 503-504. In 1986, the diocese of Campagna was completely suppressed.

On 8 September 1976, the Congregations transferred territory from the Diocese of Acerenza,"ab archidioecesi Acheruntina dividatur atque Potentinae et Marsicensi archidioecesi aggregetur paroecia B. Mariae Virginis a Monte Carmelo in pago vulgo Castelglorioso-Arioso." the Diocese of Rapolla, and from the Territorial Abbacy of Santissima Trinità di Cava de’ Tirreni"Quo Aptius," Acta Apostolicae Sedis 68 (Città del Vaticano 1976), pp. 675-677: "ab abbatia nullius Ss.mae Trinitatis Cavensis municipium vulgo Tramutola, idque archidioecesi Potentinae et Marsicensi adnectit." It also lost two towns to the diocese of Anglona-Tursi."ab archidioecesi Potentina et Marsicensi separentur et dioecesi Anglonensi-Tursiensi uniantur municipia vulgo Moliterno et Sarconi."

Following the Second Vatican Council, and in accordance with the norms laid out in the council's decree, Christus Dominus chapter 40,Christus Dominus 40. Therefore, in order to accomplish these aims this sacred synod decrees as follows: 1) The boundaries of ecclesiastical provinces are to be submitted to an early review and the rights and privileges of metropolitans are to be defined by new and suitable norms. 2) As a general rule all dioceses and other territorial divisions that are by law equivalent to dioceses should be attached to an ecclesiastical province. Therefore dioceses which are now directly subject to the Apostolic See and which are not united to any other are either to be brought together to form a new ecclesiastical province, if that be possible, or else attached to that province which is nearer or more convenient. They are to be made subject to the metropolitan jurisdiction of the bishop, in keeping with the norms of the common law. 3) Wherever advantageous, ecclesiastical provinces should be grouped into ecclesiastical regions for the structure of which juridical provision is to be made. Pope Paul VI ordered a reorganization of the ecclesiastical provinces in southern Italy. The decree Eo quod spirituales of 12 September 1976 created a new episcopal conference in the region called "Basilicata", to which were assigned all of the dioceses that belonged to the ecclesiastical province of Potenza, including Materana and Mons Pelusii; they had formerly belonged to the episcopal conference of "Apulia".The bull Eo quod spirituales , in: Acta Apostolicae Sedis 68 (1976), pp. 678-680. Pope Paul VI ordered consultations among the members of the Congregation of Bishops in the Vatican Curia, the Italian Bishops Conference, and the various dioceses concerned. After twenty years, problems and objections were still apparent.

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. The Vatican continued consultations which had begun under Pope John XXIII for the merging of small dioceses, especially those with personnel and financial problems, into one combined diocese.

On 30 September 1986, Pope John Paul II ordered that the dioceses of Potenza, Marsico Nuovo, and Muro Lucano be merged into one diocese with one bishop, with the Latin title Archidioecesis Potentina-Murana-Marsicensis. The seat of the diocese was to be in Potenza, and the cathedral of Potenza was to serve as the cathedral of the merged diocese. The cathedrals in Marsico Nuovo and Muro Lucano were to become co-cathedrals, and their cathedral Chapters were each to be a Capitulum Concathedralis. There was to be only one diocesan Tribunal, in Potenza, 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 suppressed dioceses of Marsico Nuovo and Muro Lucano.Acta Apostolicae Sedis 79 (Città del Vaticano 1987), pp. 764-766.

On 25 January 1998 the archdiocese of Potenza gained territory from the Archdiocese of Sant’Angelo dei Lombardi–Conza–Nusco–Bisaccia.

The cathedral Chapter of Potenza is currently (2022) composed of thirteen persons: ten canons (including a president, a vice-president, an economus, and a penitentiary) and three honorary canons. The president also serves as the parish priest of the cathedral parish.Arcidiocesi di Potenza: La diocesi

In 1990, the six bishops of the ecclesiastical province of Basilicata established a joint seminary for the training of priests, situated in Potenza.Major Seminary of Basilicata . The seminary of Potenza was closed, and its building was repurposed as the Osthello della Gioventù.Ex-seminario vescovile .
