According to Leo, Mary, as the living memory of Jesus, also ensures the unity of the disciples’ prayer in the upper room at Pentecost.

In the account of Pentecost in the Acts of the Apostles, “the apostles are listed by name and, as always, Peter is the first,” the pope pointed out. “But he himself, in truth, is the first to be supported by Mary in his ministry.”

“In the same way, Mother Church supports the ministry of Peter’s successors with the Marian charism. The Holy See experiences in a very special way the coexistence of the two poles; the Marian and the Petrine. It is precisely the Marian pole, with its motherhood, gift of Christ and of the Spirit, that ensures the fruitfulness and holiness of the Petrine pole,” he said.

Riva, an author and prolific spiritual writer, also spoke about the direction of one’s work and life in her reflection. “We need to work for the great horizon of life that does not die: to live by asking ourselves at every moment whether what we are doing connects us firmly to that truth which is charity and eternity; this is hope,” she underlined.

“We, dear brothers and sisters, know where we must run: The race of John and Peter towards the tomb of Christ is the only race that the Church and the world can run without fear. It is the race of those who know that hope lies in true life, eternal life.”

The meaning of a jubilee, she continued, is to help us think about the last things, the brevity of existence, and the meaning of our lives.

The nun, who founded her monastic community, which educates Catholics about Eucharistic adoration and “the passion for the beauty that saves,” recalled an oft-repeated line from the Russian author Dostoevsky that “beauty will save the world.”

This quote is incorrect, she said, because Prince Myshkin, in the novel “The Idiot,” actually asks: “What beauty will save the world?”

“The prince,” Riva explained, “is confronted with a terrible image,” a painting by Hans Holbein, “The Body of the Dead Christ in the Tomb.” The painting, also referred to as “Dead Christ,” “is a life-size Christ with sunken eyes and limbs already showing signs of necrosis,” she said.

“So the question is serious. What beauty will save the world? Will the beauty of the cross save the world? The beauty of defeat? The beauty of humiliation? Yes, the cross can still save us,” the nun emphasized. “In 2025, in postmodern man, the great salvation of the cross still exists. The cross will save us.”
