Initially, the Vatican was hesitant to declare a Feast of the Sacred Heart, but did allow the Visitandines to celebrate a Mass special to this day. As the devotion to the Sacred Heart of Jesus spread throughout France, the Vatican granted the Feast of the Sacred Heart of Jesus to France in 1765.
In 1856, after much lobbying by French bishops on behalf of the Feast of the Sacred Heart, Pope Pius IX designated the Friday following the Feast of Corpus Christi as the Feast of the Sacred Heart for the entire Latin rite Church.
On May 25, 1899, Pope Leo XIII promulgated the encyclical Annum sacrum, which consecrated the entire world to the Sacred Heart of Jesus. This encyclical was written after a nun, Sr. Mary of the Sacred Heart, sent two letters to the pope requesting that he consecrate the world to the Sacred Heart of Jesus.
Sr. Mary of the Sacred Heart wrote the letters, she said, after Jesus made the request to her. Pope Leo XIII called this encyclical and the subsequent consecration the “great act” of his papacy.
“Finally, there is one motive which We are unwilling to pass over in silence, personal to Ourselves it is true, but still good and weighty, which moves Us to undertake this celebration. God, the author of every good, not long ago preserved Our life by curing Us of a dangerous disease,” wrote Leo XIII.
“We now wish, by this increase of the honor paid to the Sacred Heart, that the memory of this great mercy should be brought prominently forward, and Our gratitude be publicly acknowledged.”
But why consecrate the world--or anyone--to the Sacred Heart of Jesus? What does that mean?
Pope Leo XIII described the act of consecration as one that will “establish or draw tighter the bonds which naturally connect public affairs with God,” which was especially needed for the world at the turn of the century.
“While many see religion as unnecessary in a world with more and more technology and resources, swearing allegiance and consecrating ourselves to Christ the King in his Sacred Heart shows that humanity still needs and longs for a compassionate and all-powerful God,” Dobrozsi, the Cincinnati priest, told CNA.
“In a society where some live in decadence and prideful luxury while others are destitute, the burning love of Christ’s Sacred Heart reminds us that the fires of his mercy are also fires of justice. And when the culture, and so many of us, feel hopeless that we could ever change after falling to sins of the flesh, the Heart of our Lord beats with powerful love, eternally declaring that true charity has triumphed over sin and death,” he added.
These are the promises the Sacred Heart of Jesus made to Saint Margaret Mary Alacoque:
1. I will give them all the graces necessary for their state of life.
2. I will give peace in their families.
3. I will console them in all their troubles.
4. I will be their refuge in life and especially in death.
5. I will abundantly bless all their undertakings.
6. Sinners shall find in my Heart the source and infinite ocean of mercy.
7. Tepid souls shall become fervent.
8. Fervent souls shall rise speedily to great perfection.
9. I will bless those places wherein the image of
My Sacred Heart shall be exposed and venerated.
10. I will give to priests the power to touch the most hardened hearts.
11. Persons who propagate this devotion shall
have their names eternally written in my Heart.
12. In the excess of the mercy of my Heart, I promise you that my all powerful love will grant to all those who will receive Communion on the First Fridays, for nine consecutive months, the grace of final repentance: they will not die in my displeasure, nor without receiving the sacraments; and my Heart will be their secure refuge in that last hour.
