Pope Boniface IV

[6] 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.

Boniface obtained leave from Emperor Phocas to convert the Pantheon in Rome into a Christian church, and on 13 May 609,[7] the temple erected by Agrippa to Jupiter the Avenger, Venus, and Mars was consecrated by the pope in honor of the Virgin Mary and all the Martyrs.

[5] 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.

[11] 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.
