INTROIT (Ps. 73. 20, 19, 23)
HAVE regard, O Lord, to Thy covenant, and forsake not to the end the souls of Thy poor: arise, O Lord, and judge Thy cause, and forget not the voices of them that seek Thee. Ps. ibid. 2. O God, why hast Thou cast us off unto the end: why is Thy wrath enkindled against the sheep of Thy pasture? ℣. Glory be to the Father, and to the Son, and to the Holy Ghost. As it was in the beginning, is now, and ever shall be, world without end. Amen. — Have regard, O Lord …
ALMIGHTY everlasting God, give to us increase of Faith, Hope and Charity: and that we may deserve to obtain what Thou dost promise, make us love what Thou dost command. Through our Lord Jesus Christ, Thy Son, Who liveth and reigneth with Thee in the unity of the Holy Ghost, God, world without end.
EPISTLE From the Letter of Blessed Paul the Apostle to the Galatians, 3. 16-22.
BRETHREN: To Abraham were the promises made, and to his seed. He saith not: and to his seeds, as of many; but as of one: And to thy seed, which is Christ. Now this I say, that the testament which was confirmed by God, the law which was made after four hundred and thirty years, doth not disannul, to make the promise of no effect. For if the inheritance be of the law, it is no more of promise. But God gave it to Abraham by promise. Why then was the law? It was set because of transgressions until the seed should come, to whom He made the promise, being ordained by angels in the hand of a mediator. Now a mediator is not of one, but God is one. Was the law then against the promises of God? God forbid. For if there had been a law given, which could give life, verily justice should have been by the law. But the Scripture hath concluded all under sin, that the promise by the faith of Jesus Christ might be given to them that believe.
GRADUAL (Ps. 73. 20, 19, 22)
HAVE regard, O Lord, to Thy covenant, and forsake not to the end the souls of Thy poor. Arise, O Lord, and judge Thy cause: remember the reproach of Thy servants. Alleluia, alleluia. (Ps. 89. 1.) Lord, Thou hast been our refuge, from generation to generation. Alleluia.
GOSPEL Continuation of the holy Gospel according to St. Luke, 17. 11-19.
AT THAT TIME, as Jesus was going to Jerusalem, He passed through the midst of Samaria and Galilee: and as He entered into a certain town, there met Him ten men that were lepers, who stood afar off, and lifted up their voice, saying: Jesus, Master, have mercy on us. Whom when He saw, He said: Go, show yourselves to the priests. And it came to pass, that, as they went, they were made clean. And one of them, when he saw that he was made clean, went back, with a loud voice glorifying God: and he fell on his face before His feet, giving thanks: and this was a Samaritan. And Jesus answering said: Were not ten made clean? And where are the nine? There is no one found to return and give glory to God, but this stranger. And He said to him: Arise, go thy way; for thy faith hath made thee whole.
OFFERTORY (Ps. 30. 15-16)
IN Thee, O Lord, have I hoped: I said, Thou art my God, my times are in Thy hands.
LOOK graciously, O Lord, upon Thy people: graciously look upon our gifts: and, appeased by this offering, mayest Thou grant us pardon and give us what we ask. Through our Lord …
PREFACE OF THE MOST HOLY TRINITY
IT is truly meet and just, right and for our salvation, that we should at all times and in all places give thanks to Thee, holy Lord, Father almighty, eternal God: Who, together with Thine onlybegotten Son and the Holy Ghost, art one God, one Lord: not in the Oneness of a single Person, but in the Trinity of one Substance. For what by Thy revelation we believe of Thy glory, the same do we believe of Thy Son, the same of the Holy Ghost, without difference or separation; so that in confessing the true and eternal Godhead, in It we should adore distinction in Persons, unity in Essence, and equality in Majesty: in praise of which Angels and Archangels, Cherubim also and Seraphim, day by day exclaim, without end and with one voice, saying: — Sanctus.
COMMUNION (Wisdom 16. 20)
THOU hast given us, O Lord, bread from heaven, having in it all that is delicious, and the sweetness of every taste.
WE who have received the heavenly Sacraments beseech Thee, O Lord, that we may steadily advance towards eternal redemption. Through our Lord …
