The Magnificat and the greatness of the Lord

Today's Gospel is almost entirely the Magnificat, that canticle of the Blessed Mother that rejoices in God's grace and mercy.
  That the Blessed Mother speaks of God routing "the proud of heart" is probably key in this canticle, as such disposition seems unlikely to elicit piety, whereas this canticle precisely shows the humility of the Blessed Mother -- immediately after the praises that St Elizabeth lavishes upon "the mother of my Lord" who is "blessed among women". After the unthinkable grace of God "inclining the heavens to come down" and save us as one of our own, nothing else but humility and rejoicing is proper! As the Blessed Mother is our perfect model on the receiving end of God's salvation, our lives should be the Magnificat sung in our every act!
