Did You Know?
When St. Boniface prepared to evangelize the pagan tribes of Germany, it was Pope St. Gregory II who commissioned and encouraged him. Gregory entrusted Boniface with broad authority to preach, organize dioceses, and reform the local churches. One of Boniface’s most famous acts – the cutting down of the pagan Oak of Thor at Geismar – symbolized the triumph of Christianity over paganism and became possible through the support and confidence placed in him by Pope Gregory II.
Why St. Gregory II Matters
Pope St. Gregory II stands at the crossroads of two defining developments in Church history: the evangelization of Central Europe and the defense of sacred images. By commissioning St. Boniface, he helped bring the Gospel to the Germanic peoples, shaping the future of Christian Europe. At the same time, his courageous resistance to Iconoclasm safeguarded the Church’s understanding that sacred images serve as powerful reminders of the mysteries of Christ and the communion of saints. His pontificate marks the emergence of the medieval papacy as both a missionary force and a steadfast guardian of apostolic tradition.

The Pope Who Sent the Apostle of Germany
In AD 719, Pope St. Gregory II entrusted the English monk St. Boniface with a mission that would transform Europe. Armed with papal authority and sustained by Gregory’s encouragement, Boniface preached the Gospel among the Germanic tribes, established dioceses, reformed clergy, and famously felled the pagan Oak of Thor, demonstrating the powerlessness of the old gods before Christ. At the same time, Gregory defended the Church against the first wave of Byzantine Iconoclasm, insisting that sacred images were not idols but visible reminders of the Incarnation and the lives of the saints. Through his missionary vision and steadfast defense of tradition, Gregory II helped shape both the spiritual map of Europe and the Church’s enduring understanding of sacred art.
