On June 11, 1899, Pope Leo XIII consecrated the entire human race to the Sacred Heart of Jesus. Not just Catholics. Not just Christian nations. Not only those who already loved and honored Christ.
The entire human race.
Leo XIII called this consecration “the great act” of his pontificate.
It was this pope who gave the Church Rerum Novarum, one of the most influential papal encyclicals in modern history. He guided the Church through enormous social, political, and cultural change, yet he saw this act of consecration to the Sacred Heart as one of the most important things he had done.
The story is tied, in part, to Blessed Mary of the Divine Heart, a religious sister who believed Our Lord was asking that the whole world be consecrated to His Sacred Heart. She wrote to Pope Leo XIII, urging him to consider the request. The pope took the matter seriously and, after reflection, issued Annum Sacrum, preparing the Church for this extraordinary act.
It is powerful to think about the pope entrusting the whole world to the Heart of Jesus at the end of the nineteenth century. The modern world was changing quickly. Industry, politics, science, and new ways of thinking were reshaping society. Many believed humanity was moving into a new age of progress. But Pope Leo XIII pointed the world back to something much more essential: the love of Christ.
Devotion to the Sacred Heart was not new. Anyone who visits older churches in Rome or throughout Europe will often see images of the Sacred Heart on side altars, in chapels, and in sacred art. This devotion had already been loved by saints and the faithful for centuries. But Leo XIII’s act gave it a universal emphasis. He was reminding the world that Christ’s Heart is the answer to the deepest needs of humanity.
Today, those needs are just as deep. We still deal with wars and division in the world. Many people feel overwhelmed by the constant stream of news, social media, political debates, and endless distractions competing for their attention.
On June 11, 2026, the bishops of the United States consecrated our nation to the Sacred Heart of Jesus as part of the 250th anniversary of the Declaration of Independence. More than a century after Pope Leo XIII consecrated the entire human race to the Sacred Heart, the Church in America is making a similar act of trust. At a time when our nation faces divisions, anxieties, and uncertainty about the future, the bishops are inviting Catholics to place their hope not in politics or programs, but in the love and mercy of Christ Himself.
Even in our own spiritual lives, we can forget that Jesus Christ is at the center of our faith. We can forget how much Christ loves us. In fact, our Savior loves us with a burning heart.
And the image of the Sacred Heart makes that love visible. The flames, the wound, the crown of thorns, and the cross all speak of Christ's love for us.
Devotion to the Sacred Heart seems to be experiencing a renewed interest, along with devotion to the Immaculate Heart of Mary. The Sacred Heart reveals the love of Christ poured out for the world. The Immaculate Heart of Mary shows the perfect human response to that love. Her heart received His love, suffered with Him, and remained united to Him.
The Sacred and Immaculate Hearts Cathedral Window Framed Print is a beautiful reminder of this devotion. Inspired by the look of sacred glass, it brings the united Hearts of Jesus and Mary into the home as a sign of love, trust, and consecration. Find yours today at The Catholic Company!
