Basis for the Mediatrix/Dispensatrix of All Graces

I’ve been trying to figure out this whole “Mary as Mediatrix of All Graces” thing. I have no problem with believing it, but I’d like to understand why we believe it, other than simply “because it’s taught by the Church.” Mind you, that’s enough to make me believe it, but I’d like to know why it’s taught by the Church. I want to know the scriptural/theological basis, and how the Church came to teach this doctrine. Thanks!

EDIT: I guess, more specifically, I’m asking about her role as Dispensatrix of all Graces. I believe there is a slight, nuanced difference between the two

Mary said yes to the Angel Gabriel.
She deserves hyperdulia.

Who is all grace? Jesus
Who did Jesus go through to get to us? Mary

Mary is the mediatrix ( fem form of mediator) of all grace


@Treacy17 , these words of the Fathers of the Second Council of the Vatican may help .

" There is but one Mediator as we know from the words of the apostle, “for there is one God and one mediator of God and men, the man Christ Jesus, who gave himself a redemption for all”. The maternal duty of Mary toward men in no wise obscures or diminishes this unique mediation of Christ, but rather shows His power. For all the salvific influence of the Blessed Virgin on men originates, not from some inner necessity, but from the divine pleasure. It flows forth from the superabundance of the merits of Christ, rests on His mediation, depends entirely on it and draws all its power from it. In no way does it impede, but rather does it foster the immediate union of the faithful with Christ.

" Predestined from eternity by that decree of divine providence which determined the incarnation of the Word to be the Mother of God, the Blessed Virgin was on this earth the virgin Mother of the Redeemer, and above all others and in a singular way the generous associate and humble handmaid of the Lord. She conceived, brought forth and nourished Christ. She presented Him to the Father in the temple, and was united with Him by compassion as He died on the Cross. In this singular way she cooperated by her obedience, faith, hope and burning charity in the work of the Saviour in giving back supernatural life to souls. Wherefore she is our mother in the order of grace.

" This maternity of Mary in the order of grace began with the consent which she gave in faith at the Annunciation and which she sustained without wavering beneath the cross, and lasts until the eternal fulfillment of all the elect. Taken up to heaven she did not lay aside this salvific duty, but by her constant intercession continued to bring us the gifts of eternal salvation. By her maternal charity, she cares for the brethren of her Son, who still journey on earth surrounded by dangers and cultics, until they are led into the happiness of their true home. Therefore the Blessed Virgin is invoked by the Church under the titles of Advocate, Auxiliatrix, Adjutrix, and Mediatrix. This, however, is to be so understood that it neither takes away from nor adds anything to the dignity and efficaciousness of Christ the one Mediator.

"For no creature could ever be counted as equal with the Incarnate Word and Redeemer. Just as the priesthood of Christ is shared in various ways both by the ministers and by the faithful, and as the one goodness of God is really communicated in different ways to His creatures, so also the unique mediation of the Redeemer does not exclude but rather gives rise to a manifold cooperation which is but a sharing in this one source.

" The Church does not hesitate to profess this subordinate role of Mary. It knows it through unfailing experience of it and commends it to the hearts of the faithful, so that encouraged by this maternal help they may the more intimately adhere to the Mediator and Redeemer. "

Well, yes, but it doesn’t immediately follow from that that she is the Mediatrix of all Grace

I’ve heard people say that all graces actually come from God, and are given to Mary to dispense to all of us as she wills, which I think is slightly different. For instance, that bit of grace that I got that helped me practice that bit of mortification? That was given by Mary

This is good, and I understand how she is a Mediatrix between us and Jesus, but I don’t understand the specific mediating/dispensing of graces between her and us

Mary is mother of the church. The church has the sacraments. The sacraments dispense grace.
