Catholic Church Tradition already embraced the view of Mary's role as Mother of the Church.
It says Saint Augustine and Pope Saint Leo the Great both reflected on the Virgin Mary’s importance in the mystery of Christ.
“In fact the former [St. Augustine] says that Mary is the mother of the members of Christ, because with charity she cooperated in the rebirth of the faithful into the Church, while the latter [St. Leo the Great] says that the birth of the Head is also the birth of the body, thus indicating that Mary is at once Mother of Christ, the Son of God, and mother of the members of his Mystical Body, which is the Church.”
Scripture, the decree says, depicts Mary at the foot of the Cross (cf. Jn 19:25). There she became the Mother of the Church when she “accepted her Son’s testament of love and welcomed all people in the person of the beloved disciple as sons and daughters to be reborn unto life eternal.” In 1964, the decree says, Pope Paul VI
“declared the Blessed Virgin Mary as ‘Mother of the Church, that is to say of all Christian people, the faithful as well as the pastors, who call her the most loving Mother’ and established that ‘the Mother of God should be further honoured and invoked by the entire Christian people by this tenderest of titles’ ”.
In CCC490, Mary's role as Mother of the Saviour required God to endowed Her with important gifts and special graces.
490 To become the mother of the Savior, Mary "was enriched by God with gifts appropriate to such a role."132 The angel Gabriel at the moment of the annunciation salutes her as "full of grace".133 In fact, in order for Mary to be able to give the free assent of her faith to the announcement of her vocation, it was necessary that she be wholly borne by God's grace.
"The most Blessed Virgin Mary was, from the first moment of her conception, by a singular grace and privilege of almighty God and by virtue of the merits of Jesus Christ, Savior of the human race, preserved immune from all stain of original sin.135" (135 Pius IX, Ineffabilis Deus (1854): DS 2803.)
My question is: in Mary's role as Mother of the Church this would entails a much greater gifts & graces because She will now be a Mother of not only of one child, but a Mother to a billion of believers or the redeemed. In human terms it would be impossible
"There are an estimated 1.2 billion Roman Catholics in the world, according to Vatican figures. More than 40% of the world's Catholics live in Latin America - but Africa has seen the biggest growth in Catholic congregations in recent years. Mar 14, 2013 - How many Roman Catholics are there in the world?
If Mary was Chosen again, too further Her Role as Mother of the Church meaning a Mother to billions of Catholic not withstanding the teaching the Mary is the Mother of all the Redeemed (including other faith"). What kind of gifts & graces from Catholic Teaching and biblical perspective Mary must possessed in order to perform the magnitude of the holy office?
I am looking for what kind of gifts & graces Mary must possessed in order to be the Mother of the Church that would attend to the care of each member towards their salvation?
Catholicism and Church Father teaching will be helpful to appreciate the biblical soundness and realities of this important teaching to give light on the Divine Power of Mary bestowed on Her by the Most High.
