The Roman Missal: Trinity Sunday and Corpus Christi (English) 1

The Masses of Trinity Sunday (with the commemoration, Epistle and Gospel of the first Sunday after Pentecost) and of the Solemnity of Corpus Christi (with the Sequence Lauda Sion), in English, as printed in the Rev. F. C. Husenbeth's Missal for the use of the Laity (London, 1853), in the form used from the Council of Trent until the liturgical reform of the 1950s. The Sundays after Pentecost are in a following book. This is the English only; the Latin of the chants and psalms is to be added. The words in square brackets are the Missal's own headings and directions. A liturgy of the Catholic Church, not scripture.
1[Trinity Sunday.]
2Introit. Tob. xii. Blessed be the holy Trinity, and undivided unity: we will give glory to him, because he hath shewn his mercy to us. O Lord, our Lord, how wonderful is your name in all the earth! Glory, &c.
3Prayer. Omnipotens. O Almighty and eternal God, who hast granted thy servants to acknowledge the glory of the eternal Trinity in the confession of the true faith, and to adore the unity in the power of thy majesty; we beseech thee, that by firmness in the same faith, we may be ever protected from all adversities. Through our Lord, &c.
4[Commemoration of the First Sunday after Pentecost.]
5Prayer. Deus in te. O God, the strength of them that hope in thee, favourably give ear to our supplications, and since without thee mortal infirmity can do nothing, grant the help of thy grace, that in fulfilling thy commandments, we may please thee both in will and action. Through our Lord, &c.
6Epistle. Romans xi. 33—36. O the depth of the riches of the wisdom and of the knowledge of God! How incomprehensible are his judgments, and how unsearchable his ways! For who hath known the mind of the Lord? Or who hath been his counsellor? Or who hath first given to him, and recompense shall be made him? For of him, and by him, and in him, are all things: to him be glory for ever. Amen.
7Gradual. Blessed art thou, O Lord, who beholdest the depths, and sittest upon the Cherubim.—Blessed art thou, O Lord, in the firmament of heaven, and worthy of praise for ever. Alleluia, alleluia.—Blessed art thou, O Lord God of our fathers, and worthy of praise for ever. Alleluia.
8Gospel. St Matthew xxviii. 18—20. At that time, Jesus said to his disciples, All power is given to me in heaven and in earth. Going, therefore, teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost. Teaching them to observe all things whatsoever I have commanded you; and behold I am with you all days, even to the consummation of the world.

11Secret. Sanctify, we beseech thee, O Lord our God, by the invocation of thy holy name, the victim of this oblation: and through the same, perfect us to thee an eternal sacrifice. Through our Lord, &c.
12Of the Sunday. We beseech thee, O Lord, to receive favourably our offerings devoted to thee, and grant them to prove to us a perpetual succour. Through our Lord, &c.

15Postcom. Proficiat. May the reception of this sacrament, O Lord our God, and the confession of the holy and eternal Trinity, and its undivided unity, profit us to the salvation of body and soul. Through, &c.
16For the Sunday. Tantis. Grant, we beseech thee, O Lord, that filled with so great gifts, we may both receive thy salutary benefits, and never cease from thy praise. Through our Lord, &c.
17[At the end of the Mass is read the Gospel of the first Sunday after Pentecost.]
18Gospel. St Luke vi. 36—41. At that time, Jesus said to his disciples, Be ye merciful, as your Father also is merciful. Judge not, and you shall not be judged. Condemn not, and you shall not be condemned. Forgive, and you shall be forgiven. Give, and it shall be given to you: good measure and pressed down, and shaken together and running over, shall be given into your bosom. For with the same measure that you shall mete withal it shall be measured to you again. And he spoke also to them a similitude: Can the blind lead the blind? do they not both fall into the ditch? The disciple is not above his master; but every one shall be perfect, if he be as his master. And why seest thou the mote in thy brother's eye, but the beam that is in thy own eye thou considerest not? or how canst thou say to thy brother, Brother, let me pull the mote out of thy eye, when thou thyself seest not the beam in thy own eye? Hypocrite, cast first the beam out of thy own eye, and then shalt thou see clearly to take out the mote from thy brother's eye. R. Deo gratias.
19Epistle of the Sunday. 1 John iv. 8—21. Dearly beloved, God is charity. By this hath the charity of God appeared towards us, because God hath sent his only-begotten Son into the world, that we may live by him. In this is charity: not as though we had loved God, but because he hath first loved us, and sent his Son to be a propitiation for our sins. My dearest, if God hath so loved us, we also ought to love one another. No man hath seen God at any time. If we love one another, God abideth in us, and his charity is perfected in us. In this we know that we abide in him, and he in us; because he hath given us of his spirit. And we have seen, and do testify, that the Father hath sent his Son to be the Saviour of the world. Whosoever shall confess that Jesus is the Son of God, God abideth in him, and he in God. And we have known, and have believed the charity which God hath to us. God is charity: and he that abideth in charity abideth in God, and God in him. In this is the charity of God perfected with us, that we may have confidence in the day of judgment: because, as he is, we also are in the world. Fear is not in charity, but perfect charity casteth out fear: because fear hath pain; and he that feareth is not in charity. Let us therefore love God, because God first hath loved us. If any man say, I love God, and hateth his brother, he is a liar. For he that loveth not his brother whom he seeth, how can he love God whom he seeth not? And this commandment we have from God, that he who loveth God love also his neighbour.
