Pope Boniface IV (Latin : Bonifatius IV; 550-8 May 615 [lower-alpha 1] ) was the bishop of Rome from 608 to his death. Boniface had served as a deacon under Pope Gregory I, and like his mentor, he ran the Lateran Palace as a monastery. As pope, he encouraged monasticism. With imperial permission, he converted the Pantheon into a church. In 610, he conferred with Bishop Mellitus of London regarding the needs of the English Church. He is venerated as a saint in the Catholic Church with a universal feast day on 8 May.


Family and early career

Boniface was born in what is now the Province of L'Aquila. His father was a physician named John. His family was of Marsi origins according to the Liber Pontificalis. [5] During the pontificate of Gregory the Great, Boniface was a deacon of the Roman Church and held the position of dispensator, that is, the first official in connection with the administration of the patrimonies. [4]


Boniface IV was elected to succeed Boniface III but a vacancy of over nine months ensued, awaiting imperial confirmation from Constantinople. He was consecrated on either 25 August, according to Duchesne, or 15 September, according to Jaffé, in 608. [4] The Vatican lists the official beginning of his papacy as 25 September.

Boniface obtained leave from Emperor Phocas to convert the Pantheon in Rome into a Christian church, and on 13 May 609, [6] the temple erected by Agrippa to Jupiter the Avenger, Venus, and Mars was consecrated by the pope to the Virgin Mary and all the Martyrs. It was the first instance in Rome of the transformation of a pagan temple into a place of Christian worship. Twenty-eight cartloads of sacred bones were said to have been removed from the Catacombs and placed in a porphyry basin beneath the high altar. [4]

In 610, Mellitus, the first bishop of London, went to Rome "to consult the pope on important matters relative to the newly established English Church". While in Rome, he assisted at a synod then being held concerning certain questions on "the life and monastic peace of monks", and, on his departure, took to England the decree of the council together with letters from the pope to Archbishop Laurence of Canterbury and to all the clergy, to King Æthelberht of Kent, and to all the Anglo-Saxons. [2] The decrees of the council now extant are spurious. The letter to Æthelberht [7] is considered spurious by Hefele, [8] questionable by Haddan and Stubbs, [9] and genuine by Jaffé. [10]

Between 612 and 615, the Irish missionary Columbanus, then living at Bobbio in Italy, was persuaded by King Agilulf of Lombardy to address a letter on the condemnation of the "Three Chapters" to Boniface IV. He told the pope that he was suspected of heresy for accepting the Fifth Ecumenical Council and exhorted him to summon a council and prove his orthodoxy. [4] There is no record of a rejoinder from Boniface.


Inspired by Gregory the Great, Boniface IV converted his house into a monastery, where he retired and died on 8 May. He was succeeded by Adeodatus I, who reversed his policy favouring monasticism. Boniface IV was buried in the portico of St. Peter's Basilica. His remains were three times removed — in the tenth or eleventh century, at the close of the thirteenth under Boniface VIII, and to the new St. Peter's on 21 October 1603. [4] Boniface IV is commemorated as a saint in the Roman Martyrology on his feast day, 8 May. [2]

<i>Liber Pontificalis</i> Book of biographies of popes

The Liber Pontificalis is a book of biographies of popes from Saint Peter until the 15th century. The original publication of the Liber Pontificalis stopped with Pope Adrian II (867–872) or Pope Stephen V (885–891), but it was later supplemented in a different style until Pope Eugene IV (1431–1447) and then Pope Pius II (1458–1464). Although quoted virtually uncritically from the 8th to 18th centuries, the Liber Pontificalis has undergone intense modern scholarly scrutiny. The work of the French priest Louis Duchesne, and of others has highlighted some of the underlying redactional motivations of different sections, though such interests are so disparate and varied as to render improbable one popularizer's claim that it is an "unofficial instrument of pontifical propaganda."

Pope Alexander II, born Anselm of Baggio, was the head of the Roman Catholic Church and ruler of the Papal States from 1061 to his death in 1073.

Antipope John VIII or Antipope John was an antipope of the Roman Catholic church, in the year 844. On the death of Pope Gregory IV, the populace of Rome declared John, a deacon with no known links to the aristocracy as his successor. They seized the Lateran Palace and enthroned him there. However, the lay aristocracy elected as pope the elderly, nobly born archpriest Sergius, ejected John from the Lateran, and swiftly crushed the opposition. Pope Sergius II's consecration was rushed through immediately, without waiting for imperial ratification from the Frankish court. Although some of his supporters wanted John put to death for what they considered his presumption, Sergius intervened to save his life and John was confined to a monastery. Nothing further is known about him.

Auxilius of Naples was an ecclesiastical writer. To him are attributed a series of writings that deal with the controversies concerning the succession and fate of Pope Formosus (891–896), and especially the validity of the orders conferred by him. Auxilius was a Frank, who was ordained a priest, or perhaps only a deacon, in Rome by Formosus, and lived later in southern Italy, apparently at Naples.

Roman Catholic Diocese of Anagni-Alatri

Papal selection before 1059 Selection of popes before 1059

The selection of the pope, the bishop of Rome and supreme pontiff of the Roman Catholic Church, prior to the promulgation of In nomine Domini in 1059 varied throughout history. Popes were often appointed by their predecessors or by political rulers. While some kind of election often characterized the procedure, an election that included meaningful participation of the laity was rare, especially as the popes' claims to temporal power solidified into the Papal States. The practice of papal appointment during this period would later result in the jus exclusivae, i.e., a right to veto the selection that Catholic monarchs exercised into the twentieth century.

The Patriarchate of Old Aquileia existed between 607 and 698 because of the Tricapitoline Schism in the Patriarchate of Aquileia. It was allied with the Arian Lombards, while the rival Patriarchate of Grado was allied with the Byzantine Empire.

The Lateran Council of 769 was a synod held in the Basilica of St. John Lateran to rectify perceived abuses in the papal electoral process which had led to the elevation of the Antipopes Constantine II and Philip. It also condemned the rulings of the Council of Hieria. It is perhaps the most important Roman council held during the 8th century.

Council of Pisa 1409 ecumenical council of the Catholic Church which attempted to halt the Western Schism

The Council of Pisa was a controversial ecumenical council of the Catholic Church held in 1409. It attempted to end the Western Schism by deposing Benedict XIII (Avignon) and Gregory XII (Rome) for schism and manifest heresy. The College of Cardinals, composed of members of both the Avignon Obedience and the Roman Obedience, who were recognized by each other and by the Council, then elected a third papal claimant, Alexander V, who lived only a few months. He was succeeded by John XXIII.
