A Shepherd Raised Up For A Crisis

Pope Saint Gregory III stands as one of those remarkable figures God raises up in moments of deep turmoil. Born in Syria and later serving as a priest in Rome, he became known for his learning, humility, and pastoral heart. When Pope Gregory II died in 731, Gregory III was among the clergy in the funeral procession. The people, recognizing his holiness and leadership, elected him pope on the spot. His pontificate lasted from 731 to 741 and unfolded during a time of intense conflict. The Byzantine emperor had launched the iconoclast movement, which rejected the veneration of sacred images, and the Lombards in Italy posed ongoing threats to Rome’s safety and stability.

Gregory’s response to these challenges revealed a man formed by faith, courage, and devotion to the Church. He defended sacred images, supported missionary work across Europe, strengthened the Church’s structures, and acted as a true father to the Christian world.

From Syria To Saint Peter’s Chair

Gregory III was born in Syria, the son of a Christian named John. Although the exact details of his early life are limited, historical accounts agree that he grew up in a Christian environment and later became a priest in Rome. While serving the Church at the Roman parish of Saint Chrysogonus, Gregory developed a reputation for integrity, pastoral charity, and steadfast devotion to the truths of the faith.

His election as pope came suddenly and dramatically. On February 11, 731, during the funeral rites for Pope Gregory II, the clergy and people of Rome acclaimed Gregory as the next bishop of Rome. After receiving the required confirmation from the Byzantine authorities in Ravenna, he was consecrated pope on March 18, 731. He became the last Syrian pope and the final non European pope until the election of Pope Francis many centuries later.

There is no striking story of personal conversion in his life because he was already a deeply committed priest. Yet his elevation to the papacy transformed him. He moved from a quiet clerical life into a role that demanded fearless defense of doctrine, careful diplomacy, and unshakable trust in God.

Holy Images and Holy Missions

Gregory III is best remembered for his defense of sacred images during the iconoclast controversy. Emperor Leo III had condemned the veneration of icons, believing it to be idolatry, and ordered the destruction of holy images. Gregory responded first with charity and persuasion. He sent letters urging the emperor to reconsider, but when his representative was arrested, he convened a synod in Rome in 731. This council condemned iconoclasm and upheld the Catholic teaching that honoring sacred images is not worshiping them but giving glory to the God who became visible in the Incarnation.

This teaching later appeared in the Catechism of the Catholic Church, which explains that “the honor rendered to an image passes to its prototype” (CCC 2132). The Incarnation makes visible representation not only permissible but fitting, because the Son of God truly took on a human face.

Gregory did more than write and preach. He built and restored churches, filled them with images of Christ, Our Lady, and the saints, and created a new oratory in St. Peter’s Basilica to house precious relics. He installed an iconostasis in Saint Peter’s decorated with marble, onyx, and sacred images, letting the very architecture proclaim the truth of the faith.

His heart for evangelization was just as strong. He confirmed and strengthened the mission of Saint Boniface in Germany, elevating him to archbishop and giving him authority to organize and reform the Church in the region. He encouraged the missionary work of Saint Willibald and supported the Church in England by granting the pallium to the archbishops of Canterbury and York. Gregory worked to restore the original ecclesial plan envisioned by Saint Gregory the Great, showing his desire for unity and missionary zeal.

In 732, Gregory addressed lingering pagan customs by forbidding Christians to eat horse meat, calling it an abomination because of its connection to pagan rituals. This action was not about food but about identity. Gregory wanted Christians to live clearly and distinctly for Christ.

Although no extravagant miracles like healings or visions are recorded during his life, one event was widely seen by Christian writers of his time as a sign of God’s intervention. After Gregory condemned iconoclasm, Emperor Leo III attempted to send a fleet to seize him. That fleet was destroyed by storms before it reached Italy, and many saw this as divine protection over the pope and the truth he defended.

Trials Without Martyrdom

Gregory III endured immense hardship, even though he did not die a martyr’s death. The emperor confiscated papal territories in Sicily and Calabria and reassigned ecclesial jurisdictions from Rome to Constantinople in retaliation for Gregory’s defense of icons. These actions weakened the papacy both economically and spiritually and pushed Rome toward closer alliances with the rising power of the Franks.

Meanwhile, the Lombards continued to threaten Rome and its surrounding territories. Gregory fortified the city walls, restored fortresses, and even purchased the stronghold of Gallese to preserve communications with Ravenna. As the threat intensified, he appealed urgently to Charles Martel for assistance. One of the few preserved quotations from Gregory reflects the urgency of the moment: “Please come at once, to show your love towards Saint Peter, and us, his own people.”

Although Charles Martel did not fully intervene, Gregory never stopped praying, teaching, defending the faith, and trusting in God’s providence. He died on November 28, 741, and was buried in the oratory he built in St. Peter’s Basilica.

Quiet Veneration After His Death

History does not preserve a detailed list of miracles worked at his tomb, but the Church has honored him for centuries as a saint. His burial place in the special oratory of St. Peter’s Basilica signifies great respect. He appears in the Roman Martyrology, and the Church celebrates his feast on December 10.

The Catechism of the Catholic Church reminds the faithful that the saints continue their mission in heaven. It teaches that those in glory “do not cease to intercede with the Father for us” (CCC 956). Pope Saint Gregory III now participates in that eternal intercession, praying that Christians will remain faithful to the truth he defended so courageously.

Learning From Gregory III

Gregory III’s witness speaks powerfully to modern believers. He lived during a time when holy images were under attack, yet he defended them because he understood that they lead the heart to Christ. Today’s world is overflowing with images, many of them distracting or harmful, yet Gregory’s life teaches that images can also elevate the soul when they reflect God’s beauty and truth.

His life encourages Christians to fill their homes and hearts with signs of Christ’s presence, to defend the teachings of the Church with charity, and to reject the cultural pressures that blur the lines between truth and error. His ban on pagan associated customs challenges believers to consider what habits or entertainments might subtly pull them away from God. His perseverance under political pressure reminds readers that holiness is not measured by worldly success but by fidelity to Christ even when the storms never fully calm.

Pope Saint Gregory III offers a model for living with courage, compassion, and clarity in confusing times. His unshakable faith invites everyone to root their lives in Christ, to surround themselves with holy reminders of God’s love, and to trust in the Lord even when earthly powers disappoint.
