The Roman Missal: Proper of Saints, May and June (English) 49
4[Commemoration of St Peter, Apostle.]
5Prayer. Deus qui beato. O God, who, conferring the keys of the kingdom of heaven, didst deliver to thy blessed apostle Peter the sacerdotal power of binding and loosing: grant that, by the help of his intercession, we may be delivered from the chains of our sins.
7Epistle. Galatians i. 11—20. Brethren, I give you to understand that the gospel which was preached by me, is not according to man. For neither did I receive it of man, nor did I learn it; but by the revelation of Jesus Christ. For you have heard of my conversation in time past in the Jews' religion: how that beyond measure I persecuted the Church of God, and wasted it; and I made progress in the Jews' religion above many of my equals in my own nation, being more abundantly zealous for the traditions of my fathers. But when it pleased him, who separated me from my mother's womb, and called me by his grace, to reveal his Son in me, that I might preach him among the gentiles, immediately I condescended not to flesh and blood. Neither went I to Jerusalem to the apostles who were before me; but I went into Arabia, and again I returned to Damascus. Then, after three years, I went to Jerusalem to see Peter, and I tarried with him fifteen days; but other of the apostles I saw none; saving James the brother of the Lord. Now the things which I write to you, behold before God I lie not.
8Gradual. He who wrought in Peter to the apostleship, wrought in me also among the gentiles; and they knew the grace of God, which was given to me.—The grace of God in me hath not been void; but his grace always remaineth in me. Alleluia, alleluia.—Holy apostle Paul, preacher of truth, and doctor of the gentiles, intercede for us. Alleluia.
9[Gospel. St Matthew x. 16—22. Jesus said to his disciples, Behold, I send you, as page 597.]
10Offertory. To me thy friends, O God, are made exceedingly honourable: their principality is exceedingly strengthened.
11Secret. Sanctify, O Lord, the offerings of thy people through the prayers of thy apostle Paul; that what are pleasing to thee by thy institution, may become more pleasing by the patronage of him suppliating for us. Through our Lord, &c.
12[For St Peter.]
14[Then of St John Baptist, as above.]
15[Preface.—Of Apostles, as in the Ordinary of the Mass, page 22.]
16Communion. Amen I say to you, that you who have left all things, and have followed me, shall receive a hundred fold, and shall possess life everlasting.
17Postcom. Perceptis Domine. Having received the mysteries, O Lord, we beseech thee, by the intercession of thy blessed apostle Paul; that what have been celebrated in his honour may profit us as a remedy. Through our Lord, &c.
18[For St Peter.]
19Postcom. Lætificet. May the sacrifice we have offered give us joy, O Lord: that as we proclaim thee wonderful in thy apostle Peter, we may receive through him the gift of thy pardon.
20[Then of St John Baptist, as above.]
