On November 18th, we honor the great apostles, Peter and Paul, remembering the dedication of the two ancient churches built over their graves. Peter is honored in the Vatican Basilica of St. Peter; Paul is honored in the Basilica of St. Paul, outside the Aurelian Walls along the Via Ostiense. The two apostles are founders and teachers of the Roman church.

Constantine built churches over the apostles’ graves in the middle of the 4th century. Besides honoring the apostles Peter and Paul, the churches were part of a wider plan of prayer, instruction and pilgrimage still seen in the Holy Year pilgrimages to Rome today. An early example of evangelization and catechesis.

From earliest times pilgrims followed a path from one church to the other, visiting a number of other Christian shrines – St. Agnes and St. Lawrence, for example–on their way. A later pilgrim map based on that ancient pilgrimage journey offers an example.

Peter was crucified on the Vatican Hill in 64 near the obelisk not far from the circus of the emperors Caligula and Nero and was butried nearby.  Constantine erected a basilica over his burial site in 326, while Sylvester was pope. Later in 1626 the present basilica replaced Constantine’s church. It’s in the process of reconstruction in the illustration above. Recent excavations have confirmed Peter’s burial place under the papal altar of this church.

Paul, tradition says, was beheaded on the Ostian Way, outside the ancient city walls, in 67. Constantine built a shrine church over the gave in 325; it was enlarged by Theodosius I in386. The church was rebuilt after a fire in 1823, according to its original measurements. The apostle’s grave lies before the main altar of the church.

Defend your Church, O Lord, by the protection of the holy Apostles, that, as she received from them. the beginnings of her knowledge of things divine, so through them she may receive, even to the end of the world, an increase in heavenly grace. Through our Lord Jesus Christ, your Son. (Collect for the feast)
