POPE #84
Pope St. Sergius I
The 84th Pope of the Catholic Church
St. Sergius I
Pope St. Sergius I was one of the most courageous popes of the early Middle Ages. During his fourteen-year pontificate, he firmly defended the traditions and doctrine of the Western Church against imperial interference while enriching the Church’s liturgical life.
He is best remembered for refusing to approve the canons of the Quinisext Council (Council in Trullo), which contained several disciplinary decrees that conflicted with long-established Western practices. Emperor Justinian II attempted to force Sergius into compliance – even ordering his arrest – but the pope’s steadfastness, together with the loyalty of the people of Rome and the army of Ravenna, prevented imperial intervention.
“We ought to obey God rather than men.”

The Pope Who Refused an Emperor
When Emperor Justinian II ordered Pope St. Sergius I to approve the disciplinary decrees of the Quinisext Council, Sergius calmly refused. The emperor responded by sending officials to arrest the pope and bring him to Constantinople. Instead of obeying, the soldiers of Ravenna and the people of Rome rallied to protect the Holy Father, forcing the imperial officials to abandon their mission. This dramatic episode marked a turning point in history, showing that the papacy could no longer be treated as merely another office under imperial control. At the same time, Sergius left the Church a lasting gift through the introduction of the Agnus Dei, a prayer that Catholics continue to sing at every celebration of the Holy Mass.
