What does it mean that Mary is the “Mediatrix of All Grace”? Apparently that’s the fifth Marian doctrine? I’ve never heard of it before!
When we say that Mary is the “Mediatrix of All Grace”, we mean that Mary cooperated and continues to cooperate in an extraordinary way in the saving mission of Christ, who alone is the unique mediator between God and man.
It may seem peculiar at first to think of a human being working with God to bring us grace, but Scripture says that all Christians are called to contribute to this vital work. Jesus alone is the Savior and Redeemer of all mankind. Yet, He also wishes to give us some participation in it.
For example, St. Paul said, “I have become all things to all men, that I might by all means save some” (1 Cor 9:22). He considered himself a steward of God’s grace that was given to him for others (Eph 3:2; cf. Rom 11:13-14; 1 Cor 7:16; 1 Tim 4:16; 2 Tim 2:10). We are “God’s fellow workers” (1 Cor 3:9), “working together with Him” (2 Cor 6:1).
Now, Mary played her part just as Paul did, but her cooperation was and is uniquely exemplary. Essentially, there are three stages or events in her life in which we see her exercise this role. First, in her fiat: Mary’s “yes” to God was the occasion for the Son to enter human history and take on our human nature. She gave Him the flesh that He nailed to the Cross for our salvation. In a very real way, she brought salvation to the world.
Secondly, at the foot of the Cross: Since she was sinless, she was able to stand with Jesus and unite her will and her suffering perfectly with the will and the suffering of her Son. This was undoubtedly rewarded with a tremendous outpouring of grace for the Church. How do we know this? Because we see from Scripture that whenever someone suffers for the sake of the Church, the Church is rewarded with an application of the grace of the Cross.
St. Paul said, “Now I rejoice in my sufferings for your sake, and … for the sake of his body, that is, the church” (Col 1:24). Paul is showing us that the Church benefits whenever we unite our sufferings with the sufferings of Christ on the Cross. This is what he did (cf. 2 Cor 1:6; 4:8-15; Phil 2:17; 3:10; Col 1:24), this is what he encouraged others to do, and this is what Mary did.
Finally, in heaven: Once Mary was assumed body and soul into heaven, she was crowned Queen of Heaven and Earth. She sits at the right hand of the King, as mothers always did in the Davidic Kingdom (cf. 1 Ki 2:19; Psa 45:9), and she intercedes on our behalf. Since “the prayers of the righteous are very powerful in their effects” (Jas 5:16), we can be sure that if anyone turns to Christ or does any good thing, it is because she intensely desired it and prayed for it.
