Sequence for the Annunciation: Peter Abelard?

Mittit ad virginem non quemvis angelum

sed fortitudinem suum archangelum

amator hominis.

Fortem expediat pro nobis nuntium

naturae faciat ut praeiudicium

in partu virginis.

Naturam superet natus Rex gloriae

regnet et imperet et zyma scoriae

tollat de medio.

Superbientium terrat fastigia

colla sublimia calcans vi propria

potens in proelio.

Foras eiciat mundamum principem

matremque faciat secum participem

Patris imperii.

Exi qui mitteris haec dona dissere

revela veteris velamen litterae

virtute nuncii.

Accede nuncia dic Ave comminus

dic plena gratia dic tecum Dominus

et dic ne timeas.

Virgo suspicias Dei depositum

in quo perficias castum propositum

et votum teneas.

Audit et suscipit puella nuncium

credit et concipit et parit filium

sed admirabilem.

Consiliarum humani generis

et Deum fortium et Patrem posteris

in fide *  stabilem.

*vel  pace

Cujus stabilitas nos reddit stabiles

ne nos mobilitas mundana labiles

secum participem.

Sed dator veniae excessa venia

per matrem gloriae obtenta gratia

in nobis habitet.

Qui nobis tribuat peccati veniam,

reatus deleat et donet patriam

in arce siderum.

Amen.

           

The lover of mankind sent to the Virgin not just any angel, but his strength, his archangel. May that angel hasten  for us the strong  message, that conquers the predisposition of nature in the birth from a virgin.  May the King of Glory, being born, surpass nature, may he reign and rule and   in  our midst separate the dross  from the leaven. May he humble the proud, powerful in battle, with his own might, trampling underfoot haughty necks. May he cast out the prince of this world and make his mother to share with him the authority of the Father. Go, you who have been sent to spread news of these gifts, lift the veil covering the ancient scripture with the might of your message. Draw near, face to face speak the message “Hail”—say “full of grace, --say “the Lord is with you” –say “do not fear”.  O Virgin, receive what God has given, by which you fulfill your chaste intention and keep your vow.  The maiden hears and accepts the announcement, she believes and conceives, and bears a son, yet a wondrous one: Counselor of the human race and mighty God,  Father of posterity in perfect faith.  Whose steadfastness makes us partakers of his own steadfastness,  lest our earthly mobility make us slip. But may the giver of pardon by his excessive forgiveness, through the Mother of Glory, once we have obtained grace, dwell in us.  May he who grants to us pardon of sin, blot out guilt, and give us the fatherland land in the starry heights. Amen.
