The Archdiocese of Milan is the metropolitan see of the ecclesiastical province of Milan, which includes the suffragan dioceses of Bergamo, Brescia, Como, Crema, Cremona, Lodi, Mantova, Pavia, and Vigevano.[1][2] It has long maintained its own Latin liturgical rite usage, the Ambrosian rite, which is still used in the greater part of the diocesan territory.[3]
Among its past archbishops, the better known are Ambrose, Charles Borromeo, Pope Pius XI and Pope Paul VI.
Milan's archdiocese is the largest in Europe,[4] and the one having the most priests in the world, with, as of 2021, 2,450 priests living in the diocese, among whom 1,712 are secular priests.
History
According to the legend, the Gospel was brought to Milan by the apostle Barnabas,[5] and the first Bishop of Milan, Anathalon, was a disciple of that apostle.[6] But a diocese cannot have been established there, as such, before 200, as the dioceses of the church evolved from the civil (Roman) dioceses following the reforms of Emperor Diocletian, for the list of the bishops of Milan names only five predecessors of Mirocles, who participated at the Lateran council held in 313 in Rome. During the persecutions of the third and early fourth century, several Christians suffered martyrdom and were venerated at Milan: among them Gervasius and Protasius (first persecution of Diocletian), Victor, Nabor and Felix, and Nazarius and Celsus. The persecutions ended in 313 when the Emperors Constantine I and Licinius issued the Edict of Milan which proclaimed the religious toleration in the Roman Empire.
Among its bishops should be named Eustorgius I and Dionysius, who firmly opposed apostasy imposed by the Roman Emperor Constantius II; Dionysus was exiled to Cappadocia (355). The Arian Emperor Constans, employing violence, then imposed Auxentius on the diocese of Milan. His appointment was bitterly opposed by the orthodox Hilary of Poitiers, who wrote a diatribe In Constantiam, condemning the emperor's actions.[7] Auxentius was deposed by a Roman synod of Pope Damasus I in 372. At the death of Auxentius, Ambrose was elected bishop by the people of Milan (374-397).[8]
Among his successors was Bishop Dacius (c. 535-552). While Pope Vigilius was on his trip to Constantinople and staying in Sicily, from 545 to 546, he received information that Bishop Decius and some other bishops had broken communion with the patriarch of Constantinople, over the issue of the Three Chapters. In 537 and 538, he lived in Rome, having fled from Milan on account of the Gothic War.[9] At some point between 537 and 546, Bishop Decius made a personal visit to Constantinople. He was in Constantinople again in 550, when he and Pope Vigilius engaged in conversations with the Emperor Justinian. He was in Constantinople with Pope Vigilius, when he died early in 552; his body was repatriated.[10]
Lombards, Greeks, and others
During the Lombard invasion, many troubles were inflicted on the church in Milan. The Schism of the Three Chapters guaranteed autonomy of the Milanese Church for 38 years, since the Lombards were enemies of the Byzantines. At the siege of Milan by the Lombard Alboin, the Bishop Honoratus (568) sought refuge in Genoa, with a great number of his clergy, which returned to Milan only 70 years later under John the Good.
On 6 April 1027, Pope John XIX and a Roman council settled the long standing issue of the independence of the diocese of Milan from the aggressions of the diocese of Ravenna.[11]
Archbishop Ariberto da Intimiano (1018–1045) was excommunicated and anathematized by Pope Benedict IX on 26 March 1038, due to his stubborn opposition to the Emperor Conrad II.[12]
In the 10th century, the archbishops of Milan became a feudatory vassal of the Emperor extending his jurisdiction to all northwest Italy. The most distinguished of these was Ariberto da Intimiano (1018–45). As the power of the burghers grew, that of the archbishops waned, and with it the imperial authority which the prelate represented, and from the 12th century Milan became a Guelph town that fought the Emperor.[13] The archbishop Ottone Visconti in the 13th-century caused himself to be proclaimed perpetual lord, thus putting an end to the Republic of Milan and establishing the power of the House of Visconti who ruled the Duchy of Milan from 1277 to 1447.
On 1 November 1535, Duke Francesco II Sforza died without heir, and the fief revereted to the sovereign, the Emperor Charles V, who had reconquered Milan from the French in 1525 at the Battle of Pavia. In 1540, he granted Milan to his son, Philip.[14]
Attempts at reform
During the brief reign of Pope Stephen IX (1057–1058), who was the brother of the duke of Lorraine, Archbishop Guido of Milan held a synod in the diocese of Novara, in a place called ad Fontanetum, where the leaders of the Patari, Arialdus and Landulfus, were excommunicated. They had been promoting a reform of the clergy in the diocese, which was directed particularly against the widespread Milanese custom of clerical marriage. The uproar in Lombardy was so severe that Archbishop Guido travelled secretly to Rome, to obtain the active support of the pope. He was severely disappointed, as many in the papal court were committed reformers. Pope Stephen removed the excommunication of Arialdus.[15]
At the accession of Pope Nicholas II in 1058, the people of Milan, at their own request, were sent an Apostolic Visitator, Cardinal Peter Damiani, to restore order in their church, which was filled with simony and priestly concubinage.[16] Archbishop Guido da Velate (1045–1071) was summoned to the synod held by Pope Nicholas in Rome in April 1059. The principal topic of discussion was simony, and Guido was among many who were accused. He was able to escape from the attack.[17] He was finally caught and, in c. 1064, he was suspended from office by Pope Alexander II (1061–1073); in early 1066, he was excommunicated.[18]
After Archbishop Guido was excommunicated, the Emperor Henry IV attempted to take advantage of the situation and had his nominee, Gotofredo da Castiglione, a canon of the cathedral, elected Archbishop while Guido was still alive.[19] Pope Alexander condemned his election.[20]
Borromeo and the synod system
The figure who marked the modern history of the church of Milan was Charles Borromeo, archbishop of Milan from 1564 to 1584,[21] who was a leading figure during the Counter-Reformation and was responsible for significant reforms in the Catholic Church. He held eleven diocesan synods: in August 1564, 4 August 1568, 1772, 16 November 1774, 1778, 1779,[22]
Cardinal Carlo Borromeo also held six provincial synods, meeting in the cathedral of Milan. The bishops of the province,[23] as well as the canons of the cathedrals and of the collegiate churches, were expected to attend. The first took place in 1565; the second in 1569; the third in 1573; the fourth in 1576; the fifth in 1579; the sixth in 1582; a seventh was planned, but he died in 1584.[24] His immediate successor, Cardinal Gaspare Visconti (1584–1595), continued Borromeo's practice, with a diocesan synod of 1586, another in 1587, a third in 1589, and again in 1590, and in 1591, and finally a sixth in 1593.[25]
His pastoral efforts were followed by his successors, such as his cousin, Cardinal Federico Borromeo (1595–1631),[26] who held diocesan synods in 1596, 1602, 1603, 1604, 1606, 1608, 1611, 1613, 1614, 1622, and 1627.[27] Cardinal Cesare Monti (1632–1650) in eighteen years held a diocesan synod in 1636, 1640, and 1650.[28] Cardinal Alfonso Litta (1652–1679) in twenty-seven years held diocesan synods in 1658 and 1669.[29] and Giuseppe Pozzobonelli (died 1783).
Chapter and Cathedral
The cathedral of Milan is dedicated to the Nativity of the Virgin Mary, It is served and administered by a corporation called the Chapter, which is composed of five dignities (the Archpriest, the Archdeacon, the Primicerius, the Provost, and the Deacon), of three personalities (the Theologus, the Penitentiarius, and the Doctor Prebendatus), and twenty-two canons ordinary.[30]
Anselm da Baggio (Anselm of Lucca) had once been canon ordinary of the cathedral of Milan, before he was elected Pope Alexander II (1061–1073).[31]
Archbishop Ottone Visconti (1262–1295) attended the Second Council of Lyon in 1274 and 1275, returning to Italy in the company of Pope Gregory X. Pope Gregory visited Milan in November 1275.[32] On 20 April 1277, Archbishop Otto decreed that all canons ordinary of the cathedral Chapter had to be members of the nobility.[33] As temporal sovereign of Milan, Archbishop Ottone established a tribunal of six members in 1282, to preside over the affairs and common defense of Milan.[34] In 1284, Otto became the first archbishop of Milan to refer to his tenure dei gratia et Apostolicae Sedis ('thanks to God and the Pope'). Later in the year, he entered into a league with Rudolf, King of the Romans, who provided him with troops to defend Milan.[35] In 1287, he arranged an alliance of Milan, Pavia, Piacenza, and Brescia with Amadeus of Savoy.[36]
By order of the Executive Directory of the Cisalpine Republic, the Chapter of the cathedral of Milan was abolished on 19 May 1798. In the Concordat of 16 September 1803, signed by Pope Pius VII and Napoleon Bonaparte, First Consul of the French Republic and President of the Italian Republic, the Chapter was restored.[37]
Napoleon Bonaparte, Emperor of the French, was crowned king of Italy, the successor state of the Italian Republic, in the cathedral of Milan, by Cardinal Giovanni Battista Caprara, on 23 May 1805.[38]
In the 20th century, two Cardinal Archbishops of Milan were elected to the papacy: in 1922, Cardinal Achille Ratti was elected as Pope Pius XI, and in 1963 Cardinal Giovanni Battista Montini was elected as Pope Paul VI. The church of Milan was governed from 1979 to 2002 by Cardinal Carlo Maria Martini, who had been a favorite of the Catholic left.
Seminaries
The Major Seminary of the archdiocese has its principal seat in Venegono Inferiore. The minor seminary is located in Seveso. On 9 September 1566, Cardinal Carlo Borromeo entered into an agreement with the Society of Jesus (Jesuits) to staff his new seminary, beginning in 1567 and continuing for two years beyond his lifetime. He also issued detailed instructions for the conduct and education of the members of the seminary and its students.[39]
