Birthday of the Virgin Mary: Mother of Christ and the Church

From the Office of Readings for the Nativity of the Blessed Virgin Mary: -

From a discourse by St Andrew of Crete 

‘The fulfilment of the law is Christ himself, who does not so much lead us away from the letter as lift us up to its spirit. For the law’s consummation was this, that the very lawgiver accomplished his work and changed letter into spirit, summing everything up in himself and, though subject to the law, living by grace ... He changed whatever was burdensome, servile and oppressive not what is light and liberating, so that we should be enslaved no longer under the elemental spirits of the world, as the Apostle says, nor held fast as bondservants under the letter of the law. 

  [...] This radiant and manifest coming of God to men most certainly needed a joyful prelude to introduce the great gift of salvation to us. The present festival, the birth of the Mother of God, is the prelude, while the final act is the fore-ordained union of the Word with flesh. Today the Virgin is born, tended and formed and prepared for her role as Mother of God, who is the universal King of the ages. 

 Justly, then, do we celebrate this mystery since it signifies for us a double grace. We are led toward the truth, and we are led away from our condition of slavery to the letter of the law. How can this be? Darkness yields before the coming of the light, and grace exchanges legalism for freedom ... Therefore, let all creation sing and dance and unite to make worthy contribution to the celebration of this day. Let there be one common festival for saints in heaven and men on earth. Let everything, mundane things and those above, join in festive celebration. Today this created world is raised to the dignity of a holy place for him who made all things. The creature is newly prepared to be a divine dwelling place for the Creator.

From Pope Benedict XVI's Homily for the Feast of the Assumption of the Blessed Virgin Mary (15 August 2012): - 

There is a beautiful passage from St Gregory the Great on St Benedict that we can apply to Mary too. St Gregory the Great says that the heart of St Benedict expanded so much that all creation could enter it. This is even truer of Mary: Mary, totally united to God, has a heart so big that all creation can enter this heart, and the ex-votos in every part of the earth show it. Mary is close, she can hear us, she can help us, she is close to everyone of us. In God there is room for man and God is close, and Mary, united to God, is very close; she has a heart as great as the heart of God. 

But there is also another aspect: in God not only is there room for man; in man there is room for God. This too we see in Mary, the Holy Ark who bears the presence of God. In us there is space for God and this presence of God in us, so important for bringing light to the world with all its sadness, with its problems. This presence is realized in the faith: in the faith we open the doors of our existence so that God may enter us, so that God can be the power that gives life and a path to our existence. In us there is room, let us open ourselves like Mary opened herself, saying: “Let your will be done, I am the servant of the Lord”. By opening ourselves to God, we lose nothing. On the contrary, our life becomes rich and great.  (emphases mine)

Hail Mary, full of grace. 
The Lord is with thee. 
Blessed art thou amongst women,
and blessed is the fruit of thy womb, Jesus. 
Holy Mary, Mother of God, 
pray for us sinners,
now and at the hour of our death. Amen.
