Pope St. Boniface IV
The 67th Pope of the Catholic Church
St. Boniface IV
Pope St. Boniface IV is best remembered for one of the most symbolic events in Christian history: the conversion of Rome’s Pantheon from a pagan temple into a Christian church.
With the permission of Emperor Phocas, Boniface transformed the magnificent ancient temple dedicated to “all the gods” into the Church of St. Mary and the Martyrs. This act became a powerful symbol of Christianity’s triumph over paganism – not by destroying Rome’s heritage, but by consecrating it to the worship of the one true God.
“You also, as living stones, are built up, a spiritual house, a holy priesthood.”

CatholicG33k Historical Highlight
When the Pantheon Became a Church
For nearly five centuries, the Pantheon stood as one of the grandest temples of pagan Rome. Then, in AD 609, Pope St. Boniface IV received the building from Emperor Phocas and consecrated it as the Church of St. Mary and the Martyrs. Relics of countless early Christian martyrs were placed within its walls, transforming a monument once dedicated to “all the gods” into a sanctuary honoring the one true God and the heroes of the faith. This remarkable act symbolizes the victory of Christianity over paganism – not through destruction, but through redemption, sanctification, and the enduring power of the Gospel.
