The Church teaches us to invoke Mary as Mediatrix of all graces.
"By the communion of sorrows and of will between Christ and Mary," says St. Pius X, "she merited to become the dispenser of all the benefits which Jesus acquired for us by shedding his Blood" (Encyclical: Ad Diem Illum).
"At first, it seemed to me that I should distance myself a bit from the Marian devotion of my childhood in order to focus more on Christ. Thanks to St. Louis de Montfort, I came to understand that true devotion to the Mother of God is actually Chritocentric; indeed, it is very profoundly rooted in the mystery of the Blessed Trinity, and the mysteries of the Incarnation and Redemption."~Bl. Pope John Paul II
