To-day being a free Saturday (but for memorial of St Christina, Virgin & Martyr, at Lauds), the Office is of Our Lady; and that means that the Benedictus antiphon is the beautiful Ave stella matutina:
Ave stella matutina, Hail, morning star,
peccatorum medicina, remedy of sinners,
mundi princeps et regina, ruler and queen of the world,
sola virgo digna dici, alone worthy to be called a virgin,
contra tela inimici against the spears of the enemy
clipeum pone salutis, interpose the shield of salvation,
tuae titulum virtutis. the sign of thy virtue.
O sponsa Dei electa, O chosen bride of God,
esto nobis via recta be for us a straight road
ad aeterna gaudia to eternal joys.
