Washington, D.C. Newsroom, Jun 19, 2020 / 01:20 pm (CNA).- Today, June 19, is the Solemnity of the Sacred Heart of Jesus. But what does that mean? 

Why are Catholics today spending time today venerating the heart of Jesus?

“Devoting ourselves to the Sacred Heart is one of the easiest, fastest, and most pleasant ways to grow in holiness,” Fr. Ambrose Dobrozsi, a priest of the Archdiocese of Cincinnati, told CNA.

“Many saints have done many things to grow close to Jesus Christ, but no way is more sure and more pleasing to Him than to consecrate ourselves to his Sacred Heart through the Immaculate Heart of his Mother,” he added.

Where does devotion to the Sacred Heart come from?

The story behind the modern iteration of the devotion to the Sacred Heart of Jesus, however, begins on December 27, 1673 at a monastery belonging to the Order of the Visitation of Holy Mary (Visitandines) in eastern France.

There, a nun named Sr. Margaret Mary Alacoque began experiencing visions of the Sacred Heart.

Those visions continued for 18 months.

During her visions, Sr. Margaret Mary learned ways to venerate the Sacred Heart of Christ.

These devotions including the concept of a holy hour on Thursdays, the creation of the Feast of the Sacred Heart after Corpus Christi, and the reception of the Eucharist on the first Friday of every month.

As with many mystics, many people were skeptical of Sr. Margaret Mary’s claims of visions. Her confessor, the then-Fr. Claude La Colombière, S.J., (now St. Claude La Colombière, S.J.) believed her, and eventually the mother superior of her community began to believe as well.

The first Feast of the Sacred Heart was celebrated privately at the monastery in 1686.

Sr. Margaret Mary died in 1690, and was canonized by Pope Benedict XV on May 13, 1920.

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.
