Willibrord was an Anglo-Saxon missionary and saint, known as the "Apostle to the Frisians" in the modern Netherlands. He became the first Bishop of Utrecht and died at Echternach, Luxembourg.

Pope Sergius I was the bishop of Rome from 15 December 687 to his death, and is revered as a saint by the Roman Catholic Church. He was elected at a time when two rivals, Paschal and Theodore, were locked in a dispute about which of them should become pope. His papacy was dominated by his response to the Quinisext Council, the canons of which he steadfastly refused to accept. Thereupon Emperor Justinian II ordered Sergius' arrest, but the Roman people and the Italian militia of the exarch of Ravenna refused to allow the exarch to bring Sergius to Constantinople.
