TTBB setting of a votive Marian antiphon. 
 
Text:
Blessed is she who believed 
that the Lord would fulfill 
his promises to her.
 
My soul glorifies the Lord
and my spirit rejoices in God, my Savior.
He looks on his humble servant
From this day all ages will call me blessed.
The Almighty has done great things for me
and Holy is his name.
 
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.
 
(Luke 1:45-49)
