Mediatrix

In Roman Catholic Mariology, the title Mediatrix refers to the intercessory role of the Blessed Virgin Mary as a mediator in the salvific redemption by her son Jesus Christ, and that he bestows graces through her. Mediatrix is an ancient title that has been used by a number of saints since at least the 5th century. Its use grew during the Middle Ages and reached its height in the writings of saints Louis de Montfort and Alphonsus Liguori in the 18th century.

A general role of mediation or intercession is attributed to Mary in Roman Catholicism, Eastern Orthodoxy and Oriental Orthodoxy, and the term "Mediatrix" was applied to her in the dogmatic constitution Lumen gentium of the Second Vatican Council. "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."

The use of the title Mediatrix and the doctrine of Mary having a higher level of saintly intercession (owing to her special relationship with her son Jesus) is distinct from the theological issues involved in the establishment of Mediatrix of all graces as a dogma. On 12 September 2015, the Congregation for Divine Worship and the Discipline of the Sacraments through the Archdiocese of Lipa, Philippines formerly declared the 1948 Marian apparition under the title Our Lady Mediatrix of All Graces to be authentic and worthy of pious belief, now rejected as non-supernatural by the Congregation of the Doctrine of the Faith on 1 June 2016.
