The Roman Missal: Proper of Saints, October (English) 27

1[October 28. Saints Simon and Jude, Apostles.—Double of the Second Class.]
2Introit. Ps. cxxxviii. To me thy friends, O God, are made exceedingly honourable: their principality is exceedingly strengthened. Ps. Lord, thou hast proved me, and known me: thou hast known my sitting down, and my rising up. Glory, &c.
3Prayer. Deus qui nos. O God, who by means of thy blessed apostles Simon and Jude hast granted us to come to the knowledge of thy name; grant that we may celebrate their eternal glory by making progress in virtues and improve by this celebration. Through our Lord, &c.
4Epistle. Ephesians iv. 7—13. Brethren, to every one of us is given grace according to the measure of the giving of Christ. Wherefore he saith, Ascending on high, he led captivity captive; he gave gifts to men. Now, that he ascended, what is it, but because he also descended first into the lower parts of the earth? He that descended is the same also that ascended above all the heavens, that he might fill all things. And he gave some apostles, and some prophets, and other some evangelists, and other some pastors and doctors, for the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ; until we all meet into the unity of faith and of the knowledge of the Son of God, unto a perfect man, unto the measure of the age of the fulness of Christ.
5Gradual. Thou shalt make them princes over all the earth: they shall remember thy name, O Lord.—Instead of thy fathers, sons are born to thee; therefore shall people praise thee. Alleluia, alleluia.—To me thy friends, O God, are made exceedingly honourable: their principality is exceedingly strengthened. Alleluia.
6Gospel. St John xv. 17—25. At that time, Jesus said to his disciples, These things I command you, that you love one another. If the world hate you, know ye that it hath hated me before you. If you had been of the world, the world would love its own; but because you are not of the world, but I have chosen you out of the world, therefore the world hateth you. Remember my word that I said to you, The servant is not greater than his master. If they have persecuted me, they will also persecute you: If they have kept my word, they will keep yours also. But all these things they will do to you for my name's sake, because they know not him that sent me. If I had not come, and spoken to them, they would not have sin; but now they have no excuse for their sin. He that hateth me, hateth my Father also. If I had not done among them the works that no other man hath done, they would not have sin; but now they have both seen and hated both me and my Father. But that the word may be fulfilled which is written in their law, They hated me without a cause. Credo.
7Offertory. Their sound went forth into all the earth: and their words to the ends of the world.
8Secret. Venerating, O Lord, the perpetual glory of thy holy apostles Simon and Jude, we beseech thee, that being freed from sin by these sacred mysteries, we may celebrate it more worthily. Through our Lord, &c.
9[Preface of the Apostles, p. 22.]
10Communion. You who have followed me, shall sit upon seats judging the twelve tribes of Israel.
11Postcom. Perceptis. Having received thy sacrament, we humbly beseech thee, O Lord, that by the intercession of thy blessed apostles Simon and Jude, what we perform in honour of their venerable sufferings, may profit us as a remedy. Through our Lord, &c.
