It is the song of the Immaculate, the Full of Grace, the Proto-Disciple, the Mother of My Lord. Our Lady shows us the soul exulting in Grace. In this song we have the emotions and expectations of the one who lives in intimate union with the Blessed Trinity, who bears God in her womb and heart.
This is the model of our relationship with God, the emotions, the hope, the trust, this what Grace brings, this is song the Church puts into the mouths of the baptised as the light of the day gives way to night's darkness.
“My soul proclaims the greatness of the Lord;
my spirit rejoices in God my savior.
for he has looked upon his lowly servant.
From this day all generations will call me blessed:
the Almighty has done great things for me,
and holy is his Name.
He has mercy on those who fear him
in every generation.
He has shown the strength of his arm,
and has scattered the proud in their conceit.
He has cast down the mighty from their thrones
and has lifted up the lowly.
He has filled the hungry with good things,
and the rich he has sent away empty.
He has come to the help of his servant Israel
for he remembered his promise of mercy,
the promise he made to our fathers,
to Abraham and his children for ever.”
