Early Christian history of Porto Porto was in ancient times Portus, the chief harbour of Rome. It owes its origin to the port built by
Claudius on the right of the
Tiber, opposite
Ostia.
Trajan enlarged the basin, and in a short time there grew around it a city which eventually became independent of Ostia. Porto became a separate city in the 4th century. Between 337 and 341, a statue was erected by the
ordo et populus civitatis Flaviae Constantinianae Portuensis. It was near Porto that
Julius Nepos compelled
Emperor Glycerius to abdicate (474). During the
Gothic War the town served the Goths (537 and 549) and the Byzantines (546–552) as a base of operations against Rome. In the 9th and 10th centuries it was sacked on several occasions by the Saracens. In 849
Pope Leo IV fortified it and established there a colony of Corsicans for the defence of the coast and the neighbouring territory, but the city continued to decay. Christianity was early established there. Several martyrs of Porto are known, including
Herculanus, Hyacinthus, Martialis,
Saturninus Epictetus,
Maprilis and
Felix. The place was also famous as the probable see of
St. Hippolytus (1st half on third century). In 314 Gregorius was bishop. The great
xenodochium, or hospice, of Pammachius was built about 398. In 682, it is recorded that
Pope Leo II was consecrated by the bishops of Ostia, Porto and Velletri (the See of Albano being vacant). The bishop of Porto was one of the seven (then six, when Porto was combined with Santa Rufina)
episcopi hebdomadarii, who presided at the high altar of the Lateran Basilica in rotation during the weekdays; the system is first mentioned at the time of
Pope Stephen III (768–772), though it was certainly much older. On 1 August 1018,
Pope Benedict VIII confirmed for Bishop Benedictus all the possessions of the church of Porto, which were named in detail and included not only the entire city of Porto, but also the Isola Lycaonia and the island with the church of S. Bartholomew, and the Transtiberine region of Rome; the grant included the complete rights over people's estates who died in his jurisdiction without an heir, or intestate, or involved in a legal situation.
Diocese of Caere The
Diocese of Cære, now
Cerveteri, has been united with that of Porto since the 12th century.
Cære was an ancient city, called at first Agylla, where the sanctuaries of Rome and the Vestals were hidden during the invasion of the Gauls; the Etruscan tombs scattered about its territory are important archeologically. Cervetri had bishops of its own until the 11th century. The earliest known was Adeodatus, who participated in the first Roman synod of Pope Symmachus in 499. Bishop Petrus attended
Pope Paul I's synod of 761; Bishop Romanus was present at
Pope Eugenius II's synod of 826; other known bishops were Adrianus (853), Crescentius (869), Annisus (995), and Stephanus (1000). The last known was Benedictus, who is recorded in 1015 and 1029.
Early Christian history of Santa Rufina Santa Rufina grew up around the basilica of the Holy Martyrs Sts. Rufina and Secunda on the
Via Aurelia, from Rome; the basilica is said to have been begun by
Pope Julius I, and was finished by
Saint Damasus. In the 9th century this town was destroyed by the Saracens, and the efforts of
Pope Leo IV and
Pope Sergius III were unable to save it from total ruin: all that remains are the remnants of the ancient basilica and a chapel. The residence of the bishops of Silva Candida was on the Insula Tiberina beside the church of Sts. Adalbert and Paulinus, while that of the bishops of Porto was on the same island near the church of San Giovanni. The bishops of Silva Candida, moreover, enjoyed great prerogatives in relation with the ceremonies of the
basilica of St. Peter. In November 1037, Bishop Petrus and all his successors were granted the office of
Bibliothecarius (Librarian) of the Holy Roman Church. The first notice of it as an episcopal see dates from the 5th century: During the schism of
antipope Clement III (Wibert of Ravenna), there was a schismatic bishop Adalbert (1084–1102), who became
antipope Adalbert (1102). He was captured, brought before
Pope Paschal II, and sent to the monastery of S. Lorenzo in Aversa. Pope
Callistus II (1119–1124) united to the See of Porto the other suburbicarian See of Silva Candida or Santa Rufina. The act was confirmed by
Pope Adrian IV, and by
Pope Gregory IX. The change is dated to 1119 by Giuseppe Cappelletti. Historically, the Bishop of Porto became the second cardinal in terms of prestige, the
Bishop of Ostia being the first, and officiated on Mondays in the
Lateran Basilica; he obtained, moreover, the other rights of the Bishop of Santa Rufina, but lost jurisdiction over the Leonine City and its environs, when they were united to the city of Rome.
Recent history In 1826, Civitavecchia was separated from the
Diocese of Viterbo and Toscanella and united with that of Porto, by
Pope Leo XII. In 1854, it was made an independent see, but sharing a bishop with Corneto (Tarquinia) as the bishop of Tarquinia e Civitavecchia. In 1986, the two dioceses were united, becoming the Dioecesis Centumcellarum-Tarquiniensis, with its seat at Civitavecchia. The Cardinal Bishop of Porto Luigi Lambruschini (1847) restored the cathedral and the episcopal palace. From the 16th century, the incumbency of prelates of the see of Porto was, as a rule, of short duration, because most of the cardinal bishops opted for the
See of Ostia and Velletri when it became vacant. It was necessary, however, to be present at the consistory in which vacancies were being filled and cardinals could opt for Ostia in order of seniority. On 10 March 1961, in the apostolic letter
Ad suburbicarias dioeceses,
Pope John XXIII abolished the right of cardinal bishops to opt for other suburbicarian sees, reserving the right of appointment to the pope. By the beginning of the 20th century, it had become apparent that the suburbicarian bishops had become overburdened with the responsibilities of their curial and diocesan duties. The increase in commerce, in roads and travel, and migration to the city, as well as the increased burden of duties in the papal administration because of the number and complexity of problems affecting the Church, made some sort of relief necessary.
Pope Pius X issued a decree,
Apostolicae Romanorum Pontificium, granting the bishops of Ostia, Porto, Albano. Palestrina, and Frascati each a suffragan bishop to carry the burden of their pastoral duties in their dioceses. The pope appointed the suffragans, who had full powers inside the diocese, subject to the cardinal's approval, but not the power to ordain or consecrate, or the right to have a throne or display their coat-of-arms. Further details were added by Pope John XXIII in his apostolic letter,
Suburbicariis sedibus, defining the suffragan bishop as "Episcopus Ordinarius", with the same powers as other residential bishops, and enumerating the privileges of the cardinal bishop. In 1914, Pope Pius X took steps to restrain the irregularities in the incomes of the six cardinal suburbicarian bishops. After consulting with the curial cardinals and with their agreement, he issued the decree
Edita a Nobis, which ordered that in the future the incomes of the cardinal bishops should be placed in a single fund, administered by the Office of Economic Affairs, to which each cardinal must render an annual account. Each year, after 6,000 Lire was to be given to each suffragan bishop, the remaining money collected was to be divided into equal portions, the bishop of Ostia to receive two portions, and each of the other bishops one portion. The decree also ordered that the bishop of Ostia, when promoted to that position, should also retain his previous bishopric; the diocese of Velitrae was to be removed from his jurisdiction, and from that point the suburbicarian sees would be: Ostiensis, Portuensis et Sanctae Rufinae, Albanensis, Praenestina, Sabinensis, Tusculana, Veliterna. == Incumbents ==
