INTROIT (Apoc. 12. 1)
A GREAT sign appeared in heaven: A woman clothed with the sun, and the moon under her feet, and on her head a crown of twelve stars. Ps. 97. 1. Sing ye to the Lord a new canticle: because He hath done wonderful things. ℣. 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. — A great sign …
ALMIGHTY everlasting God, who hast taken body and soul into heaven the Immaculate Virgin Mary, Mother of Thy Son: grant, we beseech Thee, that by steadfastly keeping heaven as our goal we may be counted worthy to join her in glory. Through the same Jesus Christ, Thy Son, our Lord, Who with Thee in the unity of the Holy Ghost liveth and reigneth God, world without end.
LESSON From the Book of Judith, 13.22-25; 15. 10.
THE Lord hath blessed thee by His power, because by thee He hath brought our enemies to nought. Blessed art thou, O daughter, by the Lord the most high God, above all women upon the earth. Blessed be the Lord who made heaven and earth, who hath directed thee to the cutting off the head of the prince of our enemies. Because He hath so magnified thy name this day that thy praise shall not depart out of the mouth of men who shall be mindful of the power of the Lord, for ever: for that thou hast not spared thy life, by reason of the distress and tribulation of thy people; but hast prevented our ruin in the presence of our God. Thou art the glory of Jerusalem, thou art the joy of Israel, thou art the honor of our people.
GRADUAL (Ps. 44. 11, 12, 14)
HEARKEN, O daughter, and see, and incline thine ear: and the King shall greatly desire thy beauty. All beautiful is the King’s daughter as she comes in, robed in cloth of gold. Alleluia, alleluia. Mary has been assumed into heaven: the angelic host rejoices. Alleluia.
GOSPEL Continuation of the holy Gospel according to St. Luke, 1. 41-50.
AT that time: Elizabeth was filled with the Holy Ghost. And she cried out with a loud voice and said: Blessed art thou among women and blessed is the fruit of thy womb. And whence is this to me that the mother of my Lord should come to me? For behold as soon as the voice of thy salutation sounded in my ears, the infant in my womb leaped for joy. And blessed art thou that hast believed, because those things shall be accomplished that were spoken to thee by the Lord. And Mary said: My soul doth magnify the Lord. And my spirit hath rejoiced in God my Savior. Because He hath regarded the humility of His handmaid: for behold from henceforth all generations shall call me blessed. Because He that is mighty hath done great things to me: and holy is His name. And His mercy is from generations to generations to them that fear Him.
OFFERTORY (Genesis 3. 15)
MAY our offering of due service rise unto Thee, O Lord: and through the prayer of the most Blessed Virgin Mary, assumed by Thee into heaven, may our hearts be set on fire with love and ever yearn for Thee. Through our Lord …
PREFACE OF THE BLESSED VIRGIN MARY
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: and that we should praise and bless and proclaim Thee in the Assumption of the Blessed Mary ever Virgin: who conceived Thine onlybegotten Son by the overshadowing of the Holy Ghost, and the glory of her virginity still abiding, gave forth to the world the eternal Light, Jesus Christ our Lord: through Whom Angels praise Thy Majesty, Dominations worship, Powers stand in awe. The Heavens and the hosts of heaven with blessed Seraphim unite, exult, and celebrate; and we entreat that Thou wouldst bid our voices too be heard with theirs, singing with lowly praise: — Sanctus.
COMMUNION (Luke 1. 48-49)
ALL generations shall call me blessed. Because He that is mighty hath done great things to me.
THROUGH the merits and prayers of the Blessed Virgin Mary, by Thee assumed into heaven, may we, O Lord, who have received the sacraments of salvation, come to the glory of the resurrection. Through our Lord…
