Our Lady Mediatrix of All Graces (Mass in Some Places)

The Feast of Our Lady, Mediatrix of All Graces

According to Father Reginald Garrigou-Lagrange, “Our Holy Mother the Church-approved during the pontificate of Pope Benedict XV the proper Mass and Office of Mary, Mediatrix of all Graces.” The Saint Andrew’s Daily Missal (1945) lists it as May 31.  

The Angelus Press missal says, “May 31 was the usual date for this Mass until the institution of the Feast of Our Lady Queen; since 1956 the day will probably vary with the Diocese.” Fr. Rock, FSSP notes the following due to the Feast of the Queenship of Mary added in 1956: "In the 1962 Roman Missal, the Mass of the Blessed Virgin Mary, Queen of All Saints and Mother of Fair Love and the Mass of the Blessed Virgin Mary, Mediatrix of All Graces are listed under May 8th along with the Mass of the Blessed Virgin Mary, Our Lady of the Sacred Heart of Jesus (Beatae Mariae Virginis D. N. a S. Corde lesu)."

While not yet a dogma of the Faith, Mary has "Mediatrix of All Graces" is widely held by the Church.

Concerning this feastday in the Dominican Rite:

Interestingly, this feast never made its way into the liturgical calendar of the Roman Rite.  It is included in the 1962 Roman Missal as an optional feast, for use in certain places and diocese.  As best as I can tell, it first appeared on the Dominican liturgical calendar in the 1940's, and it moved around a bit until it finally landed on May 8 in the 1961 calendar.  The 1949 Completotori Libellus has the feast on May 31.  The 1955 English translation of the Dominican Martyrology has the feast on May 31.  The 1959 St. Dominic Missal has it on June 7.  [In the Post Vatican II Dominican Calendar], it has been removed from the calendar of the Order, which now celebrates the Patronage of the Blessed Virgin Mary on May 8.

Christ as the One Meditator 

Concerning the title of Mediatrix, Fr. Reginald Garrigou‑Lagrange, O.P. discusses the office of mediator:

"The office of mediator belongs fully only to Jesus, the Man‑God, Who alone could reconcile us with God by offering Him, on behalf of men, the infinite sacrifice of the Cross, which is perpetuated in Holy Mass. He alone, as Head of mankind, could merit for us in justice the grace of salvation and apply it to those who do not reject His saving action. It is as man that He is mediator, but as a Man in Whom humanity is united hypostatically to the Word and endowed with the fullness of grace, the grace of Headship, which overflows on men. As St. Paul puts it: 'For there is one God, and one mediator of God and men, the man Christ Jesus: Who gave Himself for a redemption for all, a testimony in due times' (I Tim. ii, 56). \

"But, St. Thomas adds: 'there is no reason why there should not be, after Christ, other secondary mediators between God and men, who co‑operate in uniting them in a ministerial and dispositive manner.’ Such mediators dispose men for the action of the principal Mediator, or transmit it, but always in dependence on His merits.”

Our Lady as the Mediator with the Mediator

Why, though, is our Lady the Mediatrix of All Graces? Why her specifically? St. Pius X stated why: "By the communion of sorrows and of will between Christ and Mary she merited to become the dispenser of all the benefits which Jesus acquired for us by shedding His Blood" (Ad Diem Illium). This resonates with what Pope Leo XIII had previously affirmed: "It may be affirmed that, according to God's will, nothing comes to us without going through Mary's hands. Just as no one can approach the Almighty Father except through the Son, so no one can approach the Almighty Father except through the Son, so no one can approach Christ except through His Mother" (Octobri Mense)

St. John Vianney's words from a few centuries before these holy pontiffs bear similar testimony: "All the saints have a great devotion to Our Lady: no grace comes from Heaven without passing through her hands. We cannot go into a house without speaking to the doorkeeper. Well, the Holy Virgin is the doorkeeper of Heaven.”
