Mediatrix of all graces

Mediatrix of all graces is a title that some Christians use for the Blessed Virgin Mary; as the Mother of God, it includes the understanding that she mediates Divine Grace. In addition to Mediatrix, other titles are given to her in the Church: Advocate, Helper, Benefactress. In a papal encyclical of 8 September 1894, Pope Leo XIII said: "The recourse we have to Mary in prayer follows upon the office she continuously fills by the side of the throne of God as Mediatrix of Divine grace."

In Mater Populi Fidelis, the Dicastery for the Doctrine of the Faith of the Catholic Church, in November 2025, declared that the use of the titles Mediatrix, Mediatrix of all graces, and Co-Redemptrix "have limits that do not favor a correct understanding of Mary’s unique place". The Dicastery for the Doctrine of the Faith encouraged the faithful to instead use of the title Mother of God for the Blessed Virgin Mary.

The Marian title of "Mediatrix of law and graces" existed in Latin usage since the 8th century and had a high degree of acceptance in the 11th and 12th century.
