The consecration and entrustment to the Virgin Mary is a personal or collective act of Marian devotion among Catholics, with the Latin terms oblatio, servitus, commendatio and dedicatio being used in this context.^[2] Consecration is an act by which a person is dedicated to a sacred service, or an act which separates an object, location or region from a common and profane mode to one for sacred use.^[3] The Congregation for Divine Worship and the Discipline of the Sacraments clarifies that in this context, "It should be recalled, however, that the term "consecration" is used here in a broad and non-technical sense: the expression is use of 'consecrating children to Our Lady', by which is intended placing children under her protection and asking her maternal blessing for them".^[2]

Consecration to the Virgin Mary by Catholics has taken place from three perspectives: personal, societal and regional, and under a number of different titles: the Immaculate Conception, to the Immaculate Heart of Mary, or more recently to Mary, Mother of the Church. Early in the 20th century, Maximilian Kolbe, called the "Apostle of Consecration to Mary", began a vigorous programme of promoting consecration to the Immaculata.^[4] In Catholic teachings, consecration to Mary does not diminish or substitute the love of God, but enhances it, for all consecration is ultimately made to God.^[5] Theologian Garrigou-Lagrange designated personal consecration to Mary as the highest level among Marian devotions.^{[citation needed]}

Pope John Paul II's motto, Totus Tuus ("totally yours"), reflected his personal consecration to Mary. He consecrated the entire world to the Immaculate Heart of Mary.^[6]

The beginnings of the notion of "belonging to Mary" can be seen in the writings of Ephrem the Syrian in the 4th century, and a form of personal consecration to Mary dates back to the 5th century, where its practitioners were called "servants of Mary" and the practice was sometimes referred to as "holy servitude". However, the first consistent and repeated use of the concept of consecration to Mary was perhaps by Ildephonsus of Toledo in the 7th century, and Pope John VII also referred to it in the 8th century.^[7]

The notion that consecration to Mary is linked with consecration to Christ and has an ultimate Christocentric goal was already present in the 7th century writings of Ildephonsus, when he wrote: "What is delivered up to the Mother rebounds to the Son; thus passes to the King the honor that is rendered in the service of the Queen."^[7]

In the 8th century, John Damascene continued the theme of consecration to Mary, and when he wrote "to you we consecrate (anathemenoi) our minds, our souls and our bodies, in a word our very selves" he used the Greek term anathemenoi which indicates "the setting aside for sacred use".^[7]

The act of consecration of cities and regions dates back at least to the 9th century, when Abbo Cernuus of Saint-Germain-des-Prés composed a poem in which he attributed the failure of the Vikings in the Siege of Paris (885–886) to the consecration of the city to the Virgin Mary, and her protection over it.^[8] During the Medieval period, abbeys, towns and cities began to consecrate themselves to the Virgin Mary to seek her protection. In the 12th century Cîteaux Abbey in France used the motif of the "protective mantle" of the Virgin Mary which shielded the kneeling abbots and abbesses. In the 13th century Caesarius of Heisterbach was also aware of this motif, which eventually led to the iconography of the Virgin of Mercy.^[7]

Although previous saints had discussed the notion of consecration, it was only in 11th century France that Odilo at the Cluny Abbey began to spread the formal practice of personal consecration to Mary.^[9] In the 12th century, the Cistercian orders began consecrating themselves to Mary, first individually and then as a group, and this practice then spread to the Benedictines and the Carmelites.^[10]

The 17th century also saw the adoption of the custom of consecrating the month of May to the Blessed Virgin.^[10] During the 18th and 19th centuries the traditions of Marian consecration grew and by 1860 First Communion in France included an act of consecration to the Virgin Mary.^[11] By this time Marian consecrations had spread beyond continental Europe and in England Frederick Faber had composed a hymn of consecration to the Virgin Mary which included a petition to her motherly role.^[12]

Since the 19th century, devotions and consecrations to the Immaculate Heart of Mary have been encouraged by several popes including Pius IX, Pius XII and John Paul II.^[13]

Theologian Reginald Garrigou-Lagrange, a professor at the Angelicum, analyzed various forms and stages of Marian devotions. He designated personal consecration to Mary as the highest level among these devotions. In his theological analysis, Marian devotions are categorized into stages, from beginner to advanced, as follows:^[14]

• Occasional prayer, e.g. praying the Hail Mary from time to time.
• Regular and daily devotion, e.g. the devout recitation of the Rosary on a daily basis.
• A formal act of consecration to Mary, and living in habitual dependence on her, as a means of uniting with Christ.

The theology of personal consecration to Mary was further explained by Pope John Paul II in Redemptoris Mater where, building on John 19:27, he stated that the word "home" refers to the spiritual and inner life of believers, and "to take Mary into one's home" signifies a filial entrustment to her as mother in every aspect of life. John Paul II suggested the Apostle John as an example of how every Christian should respond to the gift of the spiritual motherhood of Mary.^[15]

For many centuries, the Carmelites have worn the Brown Scapular as a sign of their consecration to Mary, and her protection over them.^[35] In the year 1304, the Servite Order (Servants of Mary), whose focus was on the sorrows of Mary, was approved by the Holy See.^[36]

Over the centuries, a number of Marian movements and societies have been consecrated to the Virgin Mary, e.g. the fourth vow taken by the Marianist Fathers, whose order was formed in the 18th century, during the French Revolution includes a consecration to the Virgin Mary.^[37] In the 1948 Apostolic Constitution Bis Saeculari Pope Pius XII encouraged Marian consecrations by the Marian societies such as Sodality of Our Lady.^[38]

On Sunday, 8 October 2000, upon the completion of the ceremonies for the Jubilee of the Bishops, Pope John Paul II and the bishops consecrated and entrusted themselves and the Catholic Church in the new millennium to Mary.^[39][40]

On 12 May 2010 at the Church of the Most Holy Trinity in Fátima, on the occasion of the 10th anniversary of the beatification of Jacinta and Francisco Marto Pope Benedict XVI consecrated all priests to the Immaculate Heart of Mary.^[41][42]

The consecration of cities and regions to the Virgin Mary dates back at least to the 9th century, and during the feuding Medieval period, abbeys, towns and cities began to consecrate themselves to the Virgin Mary to seek her protection.^[7][8] In the 17th century France was consecrated to the Virgin Mary by Louis XIII and a number of other countries such as Portugal followed that trend.^[43]

In the 1917 purported apparitions of Our Lady of Fatima, the Virgin Mary is said to have specifically asked for the consecration of Russia to her Immaculate Heart.^[44]

On 31 October 1942, Pius XII made a solemn act of consecration of the Catholic Church and the whole world to the Immaculate Heart of Mary, joined by the bishops of Portugal, gathered at the Cathedral in Lisbon.^[45] The consecration was performed via a Portuguese radio broadcast, and then renewed on 8 December 1942, in Rome.^[46][47] In July 1952 Pope Pius XII specifically performed the Consecration of Russia to the Immaculate Heart of Mary via the Apostolic Letter Sacro Vergente.^[48][49]

According to author Edward Sri, given the emphasis Pius XII had placed on the Queenship of Mary, the consecration emphasized the importance Pius XII placed on the powerful role of Mary as an intercessor and a protector of humanity.^[50] Mariologist Gabriel Roschini wrote that the 1942 consecration of humanity to Mary can be viewed as an apex for Marian culture.^[51][52]

On 13 May 1982 in Fatima Portugal, Pope John Paul II again consecrated the world to the Immaculate Heart of Mary and said: "Consecrating the world to the Immaculate Heart of Mary means drawing near, through the mother's intercession, to the very fountain of life that sprang from Golgotha. This fountain pours forth unceasingly redemption and grace. In it reparation is made continually for the sins of the world. It is a ceaseless source of new life and holiness".^[53]

On 25 March 1984, Pope John Paul II again performed the solemn consecration of the world to the Immaculate Heart of Mary before the statue of the Virgin Mary of Fatima brought to Saint Peter's Square in Vatican City for the ceremony. In his "program of Marian consecration and entrustment" John Paul II considered consecration to the Immaculate Heart of Mary as Divinely intended to complement the consecration to the sacred Heart of Jesus.^[54][55]

Pope Pius XII's two consecrations were made in October 1942 and July 1952 and those of John Paul II in May 1982 and March 1984.^[53] This paralleled the consecration of the world to the Sacred Heart of Jesus by Pope Leo XIII, discussed in the encyclical Annum sacrum of May 1899.^[56][57]

On 28 June 2003 John Paul II entrusted Europe to the Virgin Mary, and renewed that entrustment again on 31 August 2003.^[58][59]

During the ongoing conflict, on 25 March 2022 Pope Francis consecrated Russia and Ukraine to the Immaculate Heart of Mary in union with bishops from all over the world to implore an end to the war.^[60]

A number of different prayers may be used as part of the consecration to the Virgin Mary. The "Act of Consecration to the Immaculate Heart of Mary" appears in the official Raccolta book of indulgenced prayers.^[81]

The prayer originally composed by Louis de Montfort is as follows:^[82]

Today, I, a faithless sinner, renew in your hands my Baptismal vows; I renounce Satan forever, his pomps and works; and I give myself entirely to Jesus Christ, the Incarnate Wisdom, and will carry my cross after Him all the days of my life, and will be more faithful to Him than I have ever been. With the entire heavenly court as my witness, I choose you this day for my Mother. I deliver and consecrate myself to you, my body and soul, myself, both interior and exterior, and the worth of my good actions, past, present and future; leaving to you the total right of disposing of me, and all that belongs to me, according to your wish, for the greater glory of God in time and in eternity.

The prayer used by Pope John Paul II as his act of entrustment of all Bishops to Mary was considerably longer. It began with John 19:26 and included the entrustment as follows: "Here we stand before you to entrust to your maternal care ourselves, the Church, the entire world. Plead for us with your beloved Son that he may give us in abundance the Holy Spirit, the Spirit of truth which is the fountain of life."^[39][83]
