Everything Jesus has he has given to his Church. That includes his Mother. She is also the mother of his mystical body, his Church and we are members of that family which he has formed called the Church.
As the years unfolded I found that every one of the great influences in my Christian life from that communion of saints to which we are all joined was profoundly "Marian." Francis of Assissi, Bernard of Clairvaux, the early fathers, St Jose Maria Escriva all the way up to my champion, Blessed John Paul II, all had a deep love and devotion to Mary as mother. I began to pray Blessed John Paul's prayer of consecration, "Totus Tuus," and made it my own.
Then, the grace was given. This little Virgin from Nazareth whose "yes" brought heaven to earth and earth to heaven went from being the mother and a mother to – "my mother."
Our Catechism reminds us "What the Catholic faith believes about Mary is based on what it believes about Christ, and what it teaches about Mary illumines in turn its faith in Christ. 'God sent forth his Son,' but to prepare a body for him, he wanted the free co-operation of a creature. For this, from all eternity God chose for the mother of his Son a daughter of Israel, a young Jewish woman of Nazareth in Galilee, 'a virgin betrothed to a man whose name was Joseph, of the house of David; and the virgin's name was Mary'" (CCC#487, 488).

So, let us reflect on the Mother of God as mother of the Church and our mother.
"Called in the Gospels 'the mother of Jesus,' Mary is acclaimed by Elizabeth, at the prompting of the Spirit and even before the birth of her son, as 'the mother of my Lord.' In fact, the one whom she conceived as man by the Holy Spirit, who truly became her Son according to the flesh, was none other than the Father's eternal Son, the second person of the Holy Trinity. Hence the Church confesses that Mary is truly 'Mother of God'" (Theotokos), (CCC, 495,496; Council of Ephesus, 431 AD).
From antiquity, Mary has been called "Theotokos," or "God-Bearer" (Mother of God). The word in Greek is "Theotokos." The term was used as part of the popular piety of the early first millennium church. It is used throughout the Eastern Church's Liturgy, both Orthodox and Catholic. It lies at the heart of the Latin Rite's deep Marian piety and devotion. This title was a response to early threats to 'orthodoxy,' the preservation of authentic Christian teaching.
A pronouncement of an early Church council, The Council of Ephesus in 431 A.D., insisted "If anyone does not confess that God is truly Emmanuel, and that on this account the holy virgin is the 'Theotokos' (for according to the flesh she gave birth to the word of God become flesh by birth) let him be anathema" (The Council of Ephesus, 431 AD).
