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.
