  • Pope Leo XIV delivers homily in Lourdes

    Pope Leo XIV called for prayer and penance during a homily at the Sanctuary of Our Lady of Lourdes in France on September 27, 2026. Addressing pilgrims, the Pope stated that the Church must heal its wounds, infidelities, and painful errors through repentance and conversion. The Pope described the Grotto of Massabielle as a place of Christian hope, particularly for those facing sickness, suffering, or old age. He noted that while modern trends attempt to redefine the value of human life in these circumstances, Lourdes serves as a site to affirm the beauty and sacredness of life as a gift from God. During the Mass, which took place on the third day of his visit to France, the Pope emphasized that true happiness is found in the promise of eternal life rather than earthly existence. He reminded the faithful that prayer and penance, joined with the suffering of Christ, have the power to change the course of events.

  • Pope Leo XIV visits Maison Bakhita in Paris

    Pope Leo XIV visited Maison Bakhita in Paris to share a message about the importance of opening oneself to others. During his second day in France, the Pope stated that history is written by those who make space for others, establish peace, and build trust rather than those who seek to dominate. The Pope noted that Saint Bakhita serves as an invitation to recognize invisible people and to free those whom modern economy and culture reduce to slavery. He emphasized that every encounter allows for an exchange of gifts, noting that no one is too poor to have something to give. Maison Bakhita was established in response to a 2017 call by Pope Francis regarding migration, which suggested that societies should welcome, protect, promote, and integrate migrants. The center opened on September 25, 2021.
