Note to my fellow Catholics: Today is the day where you can get a plenary indulgence in perpetuity (!) if you say St. Louis de Montfort’s consecration prayer to Our Lady. (See text below.)
The story behind this (from The Angelus Online):
Members of the Society of St. Pius X, and their friends and benefactors, have a special incentive for interest in St. Louis Grignion de Montfort's True Devotion to the Blessed Virgin Mary and his Total Consecration to Jesus through Mary which brings about what is called a "Holy Slavery of Love." That special incentive is the fact that one of the most zealous promoters of True Devotion and Total Consecration was none other than St. Pius X himself, a devoted "Slave of Mary."
So ardent was the desire of this Marian Pope to encourage interest in Montfort's method of devotion to Our Lady that he gave a special apostolic blessing to all those who even merely read the Treatise on True Devotion to the Blessed Virgin Mary and, at the same time, he declared: "We eagerly commend the Treatise on True Devotion." In addition to this, the Holy Father granted a plenary indulgence (on 24 December 1907), under the usual conditions, to be gained on the Feast of the Immaculate Conception, December 8th, and on the Feast of Saint Louis de Montfort, April 28, to those who recite the Montfort formula of consecration entitled "Consecration of Ourselves to Jesus Christ, the Incarnate Wisdom, by the Hands of Mary." This plenary indulgence, which Leo XIII (also a "Slave of Mary") had granted for only seven years, was now granted "inperpetuum"—in perpetuity.
So you don’t have to search for it, here is the full text of the consecration prayer:
O ETERNAL and incarnate Wisdom! O sweetest and most adorable Jesus! True God and true man, only Son of the Eternal Father, and of Mary, always virgin! I adore Thee profoundly in the bosom and splendors of Thy Father during eternity; and I adore Thee also in the virginal bosom of Mary, Thy most worthy Mother, in the time of Thine incarnation.
I give Thee thanks for that Thou hast annihilated Thyself, taking the form of a slave in order to rescue me from the cruel slavery of the devil. I praise and glorify Thee for that Thou hast been pleased to submit Thyself to Mary, Thy holy Mother, in all things, in order to make me Thy faithful slave through her.
But, alas! Ungrateful and faithless as I have been, I have not kept the promises which I made so solemnly to Thee in my Baptism; I have not fulfilled my obligations; I do not deserve to be called Thy child, nor yet Thy slave; and as there is nothing in me which does not merit Thine anger and Thy repulse, I dare not come by myself before Thy most holy and august Majesty.
It is on this account that I have recourse to the intercession of Thy most holy Mother, whom Thou hast given me for a mediatrix with Thee. It is through her that I hope to obtain of Thee contrition, the pardon of my sins, and the acquisition and preservation of wisdom.
Hail, then, O immaculate Mary, living tabernacle of the Divinity, where the Eternal Wisdom willed to be hidden and to be adored by angels and by men! Hail, O Queen of Heaven and earth, to whose empire everything is subject which is under God. Hail, O sure refuge of sinners, whose mercy fails no one. Hear the desires which I have of the Divine Wisdom; and for that end receive the vows and offerings which in my lowliness I present to thee.
I, [your name], a faithless sinner, renew and ratify today in thy hands the vows of my Baptism; I renounce forever Satan, his pomps and works; and I give myself entirely to Jesus Christ, the Incarnate Wisdom, to carry my cross after Him all the days of my life, and to be more faithful to Him than I have ever been before.
In the presence of all the heavenly court I choose thee this day for my Mother and Mistress. I deliver and consecrate to thee, as thy slave, my body and soul, my goods, both interior and exterior, and even the value of all my good actions, past, present and future; leaving to thee the entire and full right of disposing of me, and all that belongs to me, without exception, according to thy good pleasure, for the greater glory of God in time and in eternity.
Receive, O benignant Virgin, this little offering of my slavery, in honor of, and in union with, that subjection which the Eternal Wisdom deigned to have to thy maternity; in homage to the power which both of you have over this poor sinner, and in thanksgiving for the privileges with which the Holy Trinity has favored thee. I declare that I wish henceforth, as thy true slave, to seek thy honor and to obey thee in all things.
O admirable Mother, present me to thy dear Son as His eternal slave, so that as He has redeemed me by thee, by thee He may receive me! O Mother of mercy, grant me the grace to obtain the true Wisdom of God; and for that end receive me among those whom thou lovest and teachest, whom thou leadest, nourishest and protectest as thy children and thy slaves.
O faithful Virgin, make me in all things so perfect a disciple, imitator and slave of the Incarnate Wisdom, Jesus Christ thy Son, that I may attain, by thine intercession and by thine example, to the fullness of His age on earth and of His glory in Heaven. Amen.
God bless you!
I have made this Total Consecration before but I didn't know about the indulgence. Thanks for sharing!
