The Roman Missal: Proper of Saints, November 29 to January 31 (English) 22
4[Then a Commemoration of St Paul, before any other, which is always observed on Feasts of St Peter: and in like manner is made a Commemoration of him on Feasts of St Paul.]
5Prayer. Deus qui multitudinem. O God, who didst teach the multitude of the gentiles by the preaching of blessed Paul the apostle, grant us, we beseech thee, to experience his patronage with thee, whose commemoration we celebrate.
8Epistle. 1 St Peter i. 1—7. Peter, an apostle of Jesus Christ, to the strangers dispersed through Pontus, Galatia, Cappadocia, Asia, and Bithynia, elect according to the foreknowledge of God the Father, unto the sanctification of the Spirit, unto obedience, and sprinkling of the blood of Jesus Christ; grace unto you and peace be multiplied. Blessed be the God and Father of our Lord Jesus Christ, who according to his great mercy hath regenerated us unto a lively hope, by the resurrection of Jesus Christ from the dead, unto an inheritance incorruptible and undefiled, and that cannot fade, reserved in heaven for you, who by the power of God are kept by faith unto salvation, ready to be revealed in the last time. Wherein you shall greatly rejoice, if now you must be for a little time made sorrowful in divers temptations: that the trial of your faith, much more precious than gold (which is tried by the fire), may be found unto praise, and glory, and honour, at the appearing of Jesus Christ our Lord.
10[If it be after Septuagesima, instead of the Alleluia and Verse, the following is said:]
11Tract. Thou art Peter, and upon this rock I will build my Church.—And the gates of hell shall not prevail against it; and to thee I will give the keys of the kingdom of heaven.—Whatsoever thou shalt bind upon earth, shall be bound also in heaven.—And whatsoever thou shalt loose upon earth, shall be loosed also in heaven.
12Gospel. St Matthew xvi. 13—19. At that time, Jesus came into the quarters of Cesarea Philippi, and he asked his disciples, saying, Whom do men say that the son of man is? But they said, Some, John the Baptist, and other some Elias, and others Jeremias, or one of the prophets. Jesus saith to them, But whom do you say that I am? Simon Peter answered, and said, Thou art Christ, the Son of the living God. And Jesus answering, said to him, Blessed art thou, Simon Bar-Jona, because flesh and blood hath not revealed it to thee, but my Father who is in heaven: and I say to thee, That thou art Peter, and upon this rock I will build my church, and the gates of hell shall not prevail against it; and I will give to thee the keys of the kingdom of heaven; and whatsoever thou shalt bind upon earth, it shall be bound also in heaven; and whatsoever thou shalt loose on earth, it shall be loosed also in heaven.
13[Credo.]
14Offertory. Thou art Peter, and upon this rock I will build my Church, and the gates of hell shall not prevail against it; and I will give to thee the keys of the kingdom of heaven.
