Legend relates that a disciple of
Jesus Christ, one Bonifatius, preached the
Gospel in
Cagliari in the 1st century. His body was said to have been found in the 17th century, with an inscription identifying it as Bonifacius. The inscription, however, is a forgery, as is the disciple himself. There were probably bishops at Cagliari from an early date.
Athanasius of Alexandria speaks of previous episcopal martyrs (during the
Diocletian persecution most likely) in a letter to his contemporary, the first well-known bishop of Cagliari,
Lucifer (354–370). Cagliari remained
Roman Catholic despite the
Arianism prevalent at the time and many African bishops fled the Arian
Vandals to come to Cagliari. In 626/627,
Pope Honorius I summoned the bishop of Cagliari and some of his clergy to Rome, to discuss several pamphlets in circulation written against the bishop and clergy.
Pope Martin I (649–653) suspended the privilege granted to the bishop of Cagliari to consecrate the bishop of Torres (Sassari).
Pope John V (685-686) reasserted the pope's right to consecrate the bishop of Torres. The earliest reference to the metropolitanate of Cagliari occurs in a letter of
Pope Gregory I, dated July 599. The title "bishop" continues to be used. At the time of the
Second Council of Constantinople (681), Cagliari was already a
metropolitan see. It has been suggested that in the 10th and 11th century as the
giudicati of Sardinia became independent, the archbishop of Cagliari became the
de facto theocratic ruler of the island through the
Corona de Logu. In 1075,
Pope Gregory VII reproached
Archbishop Giacomo for wearing a beard, a fashion which had been introduced into Sardinia at an earlier date; the pope asked the
Judge Torchitorio I to oblige the clergy to abandon this custom.
Legateship and Primacy Pope Urban II (1088–1099) granted the archbishops of Pisa the papal legateship over the Church in Sardinia. This was confirmed by
Pope Innocent II in a bull of 22 April 1138. The grant was also confirmed by
Pope Eugenius III on 19 May 1146; by
Pope Anastasius IV (1153/1154); by
Pope Adrian IV (1157); and by
Pope Alexander III (1162). On 22 April 1138,
Pope Innocent II named Archbishop Baldwin of Pisa the metropolitan of the dioceses of Galtelli and Civita in Sardinia, and appointed him the primate over the province of Torres (Sassari). On 11 April 1176,
Pope Alexander III confirmed for Archbishop Hubaldus of Pisa all the privileges granted to Archbishop Baldwin, and in addition to the primacy of Torres added the primacy of Cagliari and Arborea. These expanded privileges were confirmed by
Lucius III in 1181,
Urban III in 1186,
Clement III in 1188,
Celestine III in 1192,
Innocent III in 1198, and
Honorius III in 1216. Archbishop Federico Visconti of Pisa (1254–1277),
totius Sardiniae primas, visited Sardinia, for the purpose of exercising his Primacy, legation and right of visitation. In 1409 the title of Primas was reassumed by the Archbishop of Cagliari, Antoninus Dexart, whence arose a controversy between those sees, which dragged on into the 20th century.
Territorial structure and changes A memorandum in the Aragonese archives of the beginning of the 14th century details the ecclesiastical structure of the island. The archdiocese of Cagliari supervised the dioceses of Dolia, Sulcis, and Suelli "et est Pisanorum". In 1420, territory was added from the suppressed
Diocese of Suelli. On 11 September 1495,
Pope Alexander VI suppressed the diocese of Galtelli with the bull "Sacrosancta Romana Ecclesia", and its territory was united to the archdiocese of Cagliari. In 1503, territory was added from the suppressed
Diocese of Dolia. By the end of the 15th century, the suffragan diocese of Sulcis was in trouble. The population of the town had nearly disappeared, and the bishop and cathedral canons had transferred their residences to Iglesias. This change was formalized by
Pope Julius II in a bull of 8 December 1503. On 7 July 1503,
Pope Alexander VI had appointed Giovanni Pilares bishop of Sulcis or Iglesias. Due to the shortage of funds, Pope Julius planned to unite the diocese with the archdiocese of Cagliari, when the see became vacant. Archbishop Pietro Pilares resigned the archbishopric on 9 January 1514, and
Pope Leo X appointed Joannes Pilares his successor as archbishoip of Cagliari. Joannes was allowed to retain the diocese of Sulcis for life. That arrangement continued for more than two centuries, until
Pope Clement XIII issued the bull "Universi Christiani Populi" on 25 June 1763, restoring the diocese of Sulcis under the title of Iglesias. Iglesias was appointed a suffragan of Cagliari. Archbishop Francisco Esquivel (1605–1624) established the diocesan clerical seminary 1622. On 8 November 1824, territory was removed from the archdiocese of Cagliari to form the
Diocese of Ogliastra. On 25 March 1926,
Pope Pius XI appointed Cardinal Gaetano Bisleti his papal legate for the ceremonies of the rededication of the church of Our Lady
de bono aere in Bono. The pope also sent a gold crown, with which the statue of the Virgin was to be crowned. On 25 April 1926, the church was declared a
minor basilica.
Pope Paul VI became the first
Pope to visit Sardinia in 1,650 years when he made his visit to Cagliari Cathedral, which is a
minor basilica.
Pope John Paul II paid a visit later.
Pope Benedict XVI visited in September 2008 while
Pope Francis visited in 2013. ==Bishops==
