From the Tridentine Mass of this great feast:

Hail, holy Mother,

thou who didst bring

forth the King who rules heaven and

earth for ever and ever.  

Impart unto Thy servants, we beseech

Thee, O Lord, the gift of Thy heavenly

grace, that to us, for whom the

childbearing of the Blessed Virgin was

the beginning of our salvation, the

votive solemnity of her nativity may

give increase of peace. Through our

Lord Jesus Christ, Thy Son, Who lives

and reigns with Thee in the unity of

the Holy Spirit, God, forever and ever. 

Thou art blessed and venerable, O

Virgin Mary, who with purity unstained

was found to be the Mother of our

Savior. Virgin Mother of God,

He whom the whole world was unable to

contain enclosed Himself in thy womb,

being made man. 

Alleluia, alleluia.

Happy art thou, O

sacred Virgin Mary, and most worthy

of all praise, for out of thee hath risen

the sun of justice, Christ, our God.

Alleluia. 

Blessed art thou, O Virgin Mary, who

didst bear the Creator of all things;

thou didst bring forth Him Who made

thee, and remainest a virgin forever. 

Blessed is the womb of the Virgin

Mary, which bore the Son of the

Eternal Father.
