A deep Marian spirituality can inform and deepen a believer’s faith:
59. We can say that in the Blessed Virgin Mary we find something I mentioned earlier, namely that the believer is completely taken up into his or her confession of faith. Because of her close bond with Jesus, Mary is strictly connected to what we believe. As Virgin and Mother, Mary offers us a clear sign of Christ’s divine sonship. The eternal origin of Christ is in the Father. He is the Son in a total and unique sense, and so he is born in time without the intervention of a man. As the Son, Jesus brings to the world a new beginning and a new light, the fullness of God’s faithful love bestowed on humanity. But Mary’s true motherhood also ensures for the Son of God an authentic human history, true flesh in which he would die on the cross and rise from the dead. Mary would accompany Jesus to the cross (cf. Jn 19:25), whence her motherhood would extend to each of his disciples (cf. Jn 19:26-27). She will also be present in the upper room after Jesus’ resurrection and ascension, joining the apostles in imploring the gift of the Spirit (cf. Acts 1:14). The movement of love between Father, Son and Spirit runs through our history, and Christ draws us to himself in order to save us (cf. Jn 12:32). At the centre of our faith is the confession of Jesus, the Son of God, born of a woman, who brings us, through the gift of the Holy Spirit, to adoption as sons and daughters (cf. Gal 4:4).
The value of virginity as a sign, or something of a guarantee, of the divine Sonship–it’s easy to see how that makes belief easier.
A more important reflection for the Church is the notion of adoption, and how Mary assists in the facilitation of that.
