Peter and Paul are the two “pillars” on which the Church of Rome is founded. Their deaths are not recorded in the Scriptures, but legend says that they both died near Rome within a few years of each other. The Basilica of St. Peter is built on the traditional site where Peter was crucified upside-down on the Vatican Hill, and the Basilica of St. Paul-outside-the-Walls marks the traditional spot where Paul, as a Roman citizen, was beheaded. As with the Nativity of John the Baptist, the importance of this solemnity is marked by an additional set of texts for a vigil Mass.

Vigil Mass, Lectionary #590

Acts 3:1–10. All power in the apostles’ ministry comes from Jesus.

Psalm of the Vigil: Ps (18) 19
The first part of this psalm, praising the God of creation, is applied in Christian imagery to the apostles who preached the message to the whole world.

Galatians 1:11–20. Like the prophets before him, Paul was chosen by God from his mother's womb. His message, like his mission, comes from God.

John 21:15–19. Early tradition associated the threefold affirmation of love in this reading with Peter's threefold denial of Jesus before his death.

Mass during the Day, Lectionary #591

Acts 12:1–11. Though Peter might have died in Jerusalem , when Herod killed James, God had other plans for him, so he was set free by divine intervention to continue his mission.

Psalm of the Day: Ps (33) 34
The psalmist sings in thanksgiving and invites the just to join in the song.

2 Timothy 4:6–8, 17–18. At the end of his life, Paul reflects on his ministry, blessed by the Lord’s presence, and on his future: “The crown of righteousness awaits me.”

Matthew 16:13–19. Simon recognizes Jesus as “the Christ, the Son of the living God.” Jesus sees in this affirmation the work of the Father, so he appoints Simon as the foundation on which the Church will be built. (“Petros”—the Greek word for “rock”—became Simon's nickname: Simon Peter. It's like calling someone “Rocky.”)
