Constantine

Pope Constantine was the last pope to visit Constantinople while it was the capital of the Byzantine Empire, and the last to go there for a personal meeting with a reigning Byzantine emperor. Later popes have visited the modern city of Istanbul, so “last pope ever” is misleading.

Invited by Justinian II, Constantine journeyed to the imperial capital in AD 710-711. Negotiations produced a compromise over the Quinisext canons, but the exact concessions are not preserved. It was the final such visit by a pope to the Byzantine imperial court.

“That they all may be one, as thou, Father, in me, and I in thee.”

John 17:21, Douay-Rheims

Overview

Pope Constantine was the last pope to visit Constantinople while it was the capital of the Byzantine Empire, and the last to go there for a personal meeting with a reigning Byzantine emperor. Later popes have visited the modern city of Istanbul, so “last pope ever” is misleading.

Invited by Justinian II, Constantine journeyed to the imperial capital in AD 710-711. Negotiations produced a compromise over the Quinisext canons, but the exact concessions are not preserved. It was the final such visit by a pope to the Byzantine imperial court.

His pontificate also witnessed renewed controversy after Emperor Philippicus Bardanes attempted to revive Monothelitism, a challenge Constantine firmly resisted.

Becoming Pope

Following the death of Pope Sisinnius, Constantine was elected Bishop of Rome.

He was consecrated on March 25, AD 708. His election came during the restored reign of Emperor Justinian II whose relationship with Rome had improved considerably since his earlier conflict with St. Sergius I.

The meetings were conducted with mutual respect.

The Quinisext Council

Instead, he reaffirmed the position established by St. Sergius I, John VII.

Constantine preserved both Catholic unity and Roman ecclesiastical discipline.

Return to Rome

After completing his mission, Constantine safely returned to Rome in AD 711. His successful diplomacy strengthened relations with the Byzantine Empire without sacrificing the integrity of the Roman Church.

His historic journey to Constantinople demonstrated that respectful dialogue with political authorities could coexist with unwavering fidelity to Catholic tradition. Without compromising the Roman Church’s discipline or doctrine, he successfully strengthened relations with the Byzantine Empire during a crucial moment in Christian history.

His steadfast resistance to the brief revival of Monothelitism under Emperor Philippicus preserved the doctrinal achievements of the Sixth Ecumenical Council and safeguarded the Church’s teaching on the two natural wills of Christ. Constantine’s leadership marked the end of an era in papal-imperial relations and prepared the Church for the growing independence of the medieval papacy.

Although later popes maintained contact with the East through letters and legates, no subsequent pope made an official visit to Constantinople during the Byzantine Empire. Constantine’s mission therefore represents the closing chapter of a unique period in the relationship between Rome and the Christian emperors of the East.

Through prudent diplomacy, unwavering fidelity to Catholic doctrine, and respectful dialogue with emperors, he demonstrated that the Church could maintain communion without compromising the integrity of the apostolic faith. His successful defense of the teachings of the Sixth Ecumenical Council ensured that the victory over Monothelitism would endure, while his historic journey foreshadowed the increasingly independent role the papacy would assume in the centuries to come.
