The Sacred (or Immaculate) Heart of Mary is a devotional title that refers to the interior life of the Blessed Virgin Mary – her joys and sorrows, her virtues and perfections, her virginal love for God, her maternal love for Jesus and her compassionate love for all mankind.
Devotion to the Heart of Mary is a natural result of devotion to the Heart of Jesus, so that once devotion to the Heart of Jesus was established in the Church, devotion to the Heart of Mary could not fail to be established too.
Like devotion to the Sacred Heart of Jesus, the modern form of devotion to the Sacred Heart of Mary had its origins in France in the 17th century. Saint John Eudes, Saint Mary Margaret Alacoque and Saint Claude de la Colombiere combined devotion to the Heart of Mary with devotion to the Heart of Jesus and did much to promote them.
In 1805 Pope Pius VII approved the celebration of the Feast of the Most Pure Heart of Mary on the Sunday after the Octave of the Assumption in all dioceses and religious bodies that requested it, and in 1855 a proper Office and Mass for the feast was approved by the Sacred Congregation of Rites.
However, it was not until the second decade of the 20th century that the devotion to the Heart of Mary received a new impetus. At the height of the First World War, with Russia on the brink of revolution, the Blessed Virgin Mary appeared at Fatima in Portugal. On 13 July 1917 Our Lady asked for the consecration of Russia to her “Immaculate Heart†and revealed that God desired to establish in the world devotion to that Heart to save souls from Hell and bring peace to the world.
In 1942 the Venerable Pope Pius XII solemnly consecrated the world – once again torn by war – to the Immaculate Heart of Mary. In 1944 he extended the Feast of the Immaculate Heart of Mary to the universal Church and ordered it to be celebrated with a new Office and Mass on the 22nd of August.
The Pope told the Catholic world that
"With this devotion the Church renders the honour due to the Immaculate Heart of the Blessed Virgin Mary, since under the symbol of this Heart she venerates with reverence the eminent and singular holiness of the Mother of God, and especially her most ardent love for God and Jesus her Son, and moreover her maternal compassion for all those redeemed by the divine Blood."
Devotion to the Sacred Heart of Mary is so closely related to devotion to the Sacred Heart of Jesus that after the Second Vatican Councils Pope Paul VI ordered the Feast of the Immaculate Heart of Mary to be celebrated on the day after the Feast of the Sacred Heart of Jesus.
However, for Catholics who celebrate the Church's feasts and liturgy according to the calendar and liturgical books approved by Blessed Pope John XXIII in 1962, the Feast of the Immaculate Heart of Mary is still observed on 22 August, the Octave of the Assumption.
