If you can find one other Christian who has Blessed Virgin Mary’s “credentials”…your question has merit…to at least ask. But given the “data”…the question (in an apologetics…a theological…or a comparative analysis sense…not you as a person or a Christian)…has no real merit.
Just for fun…lets say an Angel…disguised as a Pew Research Fellow…could take a “person from another world”…show him/her/? all of the “objective” Judeo- Christian data – OT & NT-- plus all the other objective historical data records for the last 4000+ years)…and…after extensive review and study…Angel–the Pew Fellow told that “other world person” that they could meet one human person of their choosing of the Judeo-Christian heritage and history…except The Christ himself. Who do you think that “other world person” would choose?..and…lets add some “spice”…say, you were in Las Vegas visiting the Wynn Hotel at their Race and Sports Book betting lounge…(I am confessing my sins here…except the Jack Daniels part)…and they (first casino to do so on non Sports events) were taking bets on who this “person from another world”…was going to choose …and the betting boards had displayed all the names of every know Judeo-Christian person (including you and me)…who would you place your bet on?
So…if we just use a “thimbleful” of God’s gifts:…first His Grace…and then his gift of Faith in response to our “Yes” to his Grace…then couple that Grace and Faith with his gifts of our intellect, will and reasoning that we got upon our creation…in His Image and Likeness…the Blessed Virgin Mary’s importance and position to and for each and every Christian…based on her role in God’s Economy of Salvation plan and subsequent importance in and for the Church…in and for the Body of Christ…is…well…a no brainier!..IMHO.
Mary - “Blessed is she who believed”
148 The Virgin Mary most perfectly embodies the obedience of faith. By faith Mary welcomes the tidings and promise brought by the angel Gabriel, believing that “with God nothing will be impossible” and so giving her assent: "Behold I am the handmaid of the Lord; let it be [done] to me according to your word."12 Elizabeth greeted her: "Blessed is she who believed that there would be a fulfillment of what was spoken to her from the Lord."13 It is for this faith that all generations have called Mary blessed.14
149 Throughout her life and until her last ordeal 15 when Jesus her son died on the cross, Mary’s faith never wavered. She never ceased to believe in the fulfillment of God’s word. And so the Church venerates in Mary the purest realization of faith.
"Rejoice, you who are full of grace"
721 Mary, the all-holy ever-virgin Mother of God, is the masterwork of the mission of the Son and the Spirit in the fullness of time. For the first time in the plan of salvation and because his Spirit had prepared her, the Father found the dwelling place where his Son and his Spirit could dwell among men. In this sense the Church’s Tradition has often read the most beautiful texts on wisdom in relation to Mary.101 Mary is acclaimed and represented in the liturgy as the “Seat of Wisdom.”
In her, the “wonders of God” that the Spirit was to fulfill in Christ and the Church began to be manifested:
722 The Holy Spirit prepared Mary by his grace. It was fitting that the mother of him in whom "the whole fullness of deity dwells bodily"102 should herself be “full of grace.” She was, by sheer grace, conceived without sin as the most humble of creatures, the most capable of welcoming the inexpressible gift of the Almighty. It was quite correct for the angel Gabriel to greet her as the “Daughter of Zion”: "Rejoice."103 It is the thanksgiving of the whole People of God, and thus of the Church, which Mary in her canticle104 lifts up to the Father in the Holy Spirit while carrying within her the eternal Son.
723 In Mary, the Holy Spirit fulfills the plan of the Father’s loving goodness. Through the Holy Spirit, the Virgin conceives and gives birth to the Son of God. By the Holy Spirit’s power and her faith, her virginity became uniquely fruitful.105
724 In Mary, the Holy Spirit manifests the Son of the Father, now become the Son of the Virgin. She is the burning bush of the definitive theophany. Filled with the Holy Spirit she makes the Word visible in the humility of his flesh. It is to the poor and the first representatives of the gentiles that she makes him known.106
725 Finally, through Mary, the Holy Spirit begins to bring men, the objects of God’s merciful love,107 into communion with Christ. And the humble are always the first to accept him: shepherds, magi, Simeon and Anna, the bride and groom at Cana, and the first disciples.
726**** At the end of this mission of the Spirit, Mary became the Woman, the new Eve (“mother of the living”), the mother of the “whole Christ.”****108 As such, she was present with the Twelve, who "with one accord devoted themselves to prayer,"109 at the dawn of the “end time” which the Spirit was to inaugurate on the morning of Pentecost with the manifestation of the Church.
