Feast of the Dedication of the Lateran Basilica in Rome [C]

November 9, 2025

John 2:13-22

Today, the Church celebrates the Dedication of the Basilica of St. John Lateran in Rome. While many of us may be unfamiliar with this basilica, and others may wonder why its dedication is celebrated with such solemnity. To understand why, we must journey back to the earliest days of the Catholic Church.

The first Christian community in Rome was likely established around 33-34 AD. The Acts of the Apostles tells us that Jewish pilgrims from Rome were present at Pentecost, heard Peter’s preaching, were baptized, and carried the faith back to the imperial capital (Acts 2:1-42). This was the seed of the Church in Rome. When St. Peter himself arrived, he was recognized as the leader—the first Bishop of Rome.

For centuries, this fledgling Church endured severe persecution. The first state-sanctioned persecution began under Emperor Nero in 65 AD, who scapegoated Christians for a great fire in Rome. Nero’a persecution claimed the lives of the great Apostles Peter and Paul. The most systematic and brutal persecution, however, came later under Emperor Diocletian (303-311 AD), who ordered the destruction of scriptures, sacred places, and the execution of Christians across the empire.

This era of darkness gave way to light. After Diocletian, the empire fell into civil wars. Several generals, including Constatine, fought for the throne. On the eve of the decisive Battle of the Milvian Bridge, near Rome, in 312 AD, Constantine reportedly saw a vision of a cross in the sky with the words, “En Toutō Nika”—”In this sign, conquer.” Following a dream of Christ, he had his soldiers mark their shields with the Chi-Rho (☧). After his victory, Constantine not only ended the persecution of Christians but became a powerful patron of the Church.

In thanksgiving, he donated the former property of the Lateran family to the Church. On this land, he built a great basilica dedicated to Christ the Savior—the first public papal basilica (later, it would be dedicated also to St. John the Baptist and St. John the Evangelist). Pope St. Silvester accepted this gift and established it as his cathedral, the official seat of the Bishop of Rome. This was a monumental shift: the Church emerged from the hidden catacombs into the public square, a powerful sign of God’s providence and victory.

This is why the Basilica of St. John Lateran holds the title “Omnium Urbis et Orbis Ecclesiarum Mater et Caput”—”The Mother and Head of All Churches in the City and the World.” Though the popes moved their residence to the Vatican in the 14th century after a fire, the Lateran remains the Pope’s cathedral. Therefore, in celebrating its dedication, we celebrate the very foundation of the Church of Rome, the See of Peter, and the triumph of Christ’s Church over evil.

Guide questions:

Are we truly aware of the rich and long history of our Church? Do we recognize that we belong to a greater, universal Catholic family spread across the world? How deeply do we live our faith each day? Have we ever experienced persecution, or are we blessed with the freedom to express our faith openly? What are we doing—personally and as a community—to help our Church grow in faith, love, and witness?
