Pope Leo XIV Celebrates Mass in Paris Before 800,000

Pope Leo XIV celebrated an open-air Mass in central Paris on Saturday, drawing an estimated 800,000 people, according to Vatican estimates. The event occurred during the pontiff’s four-day apostolic visit to France and demonstrated the church’s continued influence despite declining attendance and secularizing trends across Europe. Following the Mass, Pope Leo XIV traveled to Lourdes to pray at the Grotto of Massabielle, a prominent Catholic pilgrimage site.

France24 reported that Vatican estimates placed the crowd size at over 800,000, while PBS Newshour also reported the 800,000 figure. Both outlets noted the turnout as evidence of the church's lasting influence in France, despite broader secular trends. France24 also mentioned a conversation with Father Grégoire Catta, but did not detail the content of that conversation.
