Pope Honorius I was the bishop of Rome from 27 October 625 to his death. He was active in spreading Christianity among Anglo-Saxons and attempted to convince the Celts to calculate Easter in the Roman fashion. He is chiefly remembered for his correspondence with Patriarch Sergius I of Constantinople over the latter's monothelite teachings. Honorius was posthumously anathematized, initially for subscribing to monothelitism, and later only for failing to end it. The anathema against Honorius I became one of the central arguments against the doctrine of papal infallibility.
Pope Boniface IV, OSB 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.

Participants were overwhelmingly Eastern bishops—only sixteen Western bishops were present, including nine from Illyricum and seven from Africa, but none from Italy—out of the 152 total.

Caesarius of Arles, sometimes called "of Chalon" from his birthplace Chalon-sur-Saône, was the foremost ecclesiastic of his generation in Merovingian Gaul. Caesarius is considered to be of the last generation of church leaders of Gaul who worked to integrate large-scale ascetic elements into the Western Christian tradition. William E. Klingshirn's study of Caesarius depicts Caesarius as having the reputation of a "popular preacher of great fervour and enduring influence". Among those who exercised the greatest influence on Caesarius were Augustine of Hippo, Julianus Pomerius, and John Cassian.
