Psalm 45

O Lady, thou art our refuge in all our needs: and a most powerful force bruising and crushing our enemy. The world is full of thy benefits: they surpass the heavens and penetrate the depths. By the fullness of thy grace those who were in the abyss rejoice to find themselves liberated. By the power of thy virginal fecundity, those who were above this world: rejoice to find themselves freed. By the glorious Son of thy most holy virginity: men are made companions and fellow-citizens of the angels. Glory be to the Father, etc.
