“Frari Assumption” by Tiziano Vecelli, altarpiece in Venice, 1518
Beautiful prayers from the Tridentine Mass of the Assumption:
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 Spirit, as it was in the beginning, is now, and ever shall be, world without end. Amen. 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.
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 lives and reigns with Thee in the unity of the Holy Spirit, God, forever and ever.
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.
I will put enmities between thee and the woman, and thy seed and her seed.
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 Jesus Christ, Thy Son, Who lives and reigns with Thee in the unity of the Holy Spirit, God, forever and ever.
It is truly meet and just, right and for our salvation that we always and everywhere give thanks unto Thee, O holy Lord, Father almighty, everlasting God: and that we should praise and bless, and proclaim Thee, in this feast of the Blessed Virgin Mary, ever Virgin: Who also conceived Thine only-begotten Son by the overshadowing of the Holy Spirit, and the glory of her virginity still abiding, gave forth to the world the everlasting Light, Jesus Christ our Lord. Through whom the Angels praise Thy majesty, the Dominations adore, the Powers tremble: the heavens and the hosts of heaven, and the blessed Seraphim, together celebrate in exultation. With whom, we pray Thee, command that our voices of supplication also be admitted in confessing Thee saying:
Sanctus, Sanctus, Sanctus,
Dóminus Deus Sábaoth. Pleni sunt
cæli et terra glória tua. Hosánna in
excélsis! Benedíctus qui venit in
nómine Dómini. Hosánna in excélsis!
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 Jesus Christ, Thy Son, Who lives and reigns with Thee in the unity of the Holy Spirit, God, forever and ever.
The following commentary on the Mariology of the Assumption, is from a wonderful resource which I have used a lot: extraordinaryform.org
“Among the feasts of the Blessed Virgin that of the Dormitio Sanctae Mariae, or of her bodily Assumption into heaven, was from very early times the most solemn and the most widely observed. In the time of Pope Sergius I a solemn procession proceeded to St. Mary Major, where Mass was celebrated. It was customary to carry images of the Savior and of His Blessed Mother in this procession; outside of Rome a similar ceremony was observed. It should, however, be borne in mind that though the divine maternity of theBlessed Virgin Mary may be regarded as the immediate reason of her Assumption into heaven, yet the first and formal reason of this privilege is to be sought in her Immaculate Conception. It is true, indeed, that the dignity of the Mother of the Incarnate Word was the primary reason for which God preserved the Immaculate Conception of Mary from all stain of original sin – and in this sense the Gregorian Sacramentary rightly attributes the reason of the bodily resurrection of the Blessed Virgin to her prerogative as Mother of the Word – but in order to express this truth with perfect accuracy, it is necessary to say that the formal reason for the preservation of her body from corruption was precisely her immunity from all stain of original sin.”
