Flag-waving crowds packed the Champs-Élysées and Place de la Concorde as the American pope traveled roughly 1.2 miles through central Paris in the popemobile before celebrating Mass. The Vatican estimated attendance at 800,000, roughly 200,000 more people than had registered in advance. People of faith gathered in the streets, with families lifting babies and young children toward the popemobile as Leo made his way through the French capital.

"From this beautiful city of Paris, I pray fervently that the living water of the Holy Spirit may flow throughout France."

Today, the square is closely associated with the French republic and regularly hosts Bastille Day celebrations. The decision to celebrate a papal Mass there drew criticism from supporters of France’s strict separation of church and state, who argued another site would have been more appropriate. The images also offered a striking contrast with another massive Paris spectacle just two years earlier. The 2024 Summer Olympics opening ceremony drew worldwide controversy over a tableau featuring drag performers that Christian leaders and other critics said mocked Christianity.

The pontiff is making his first official visit to France from Sept. 25-28 with stops in Paris, Lourdes, and Metz. While in Paris, his agenda includes a meeting with French President Emmanuel Macron, a prayer service at Notre-Dame Cathedral, and the open-air Mass along the Champs-Élysées. The trip marks the first papal visit to the European country since Benedict XVI visited in 2008. (Corbis via Getty Images) The French Bishops’ Conference said at the time that the ceremony "included scenes of mockery and derision of Christianity," adding that Christians around the world had been "hurt by the outrageousness and provocation of certain scenes." The tableau was widely interpreted by critics as a parody of Leonardo da Vinci’s "The Last Supper," though Olympics organizers disputed that interpretation. Leo’s visit comes as France experiences a notable increase in adult conversions even as the country continues a decades-long decline in overall Catholic participation. Annual adult baptisms in France have tripled since 2016, reaching 13,000 this year, according to The Associated Press. Overall baptisms, however, have fallen sharply over the longer term, from 513,000 in 1980 to 186,000 in 2024.

The scale of the pope’s reception was already apparent the night before the Mass as some 80,000 young people packed France’s national stadium Friday for a vigil featuring fireworks and a theatrical retelling of the country’s Catholic history. "Thank you for your courage! Thank you for your presence," Leo told them in French. "Thank you for your faith. You are the saints of France!"

He also invoked French Catholic saints including Irenaeus, Martin and Francis de Sales while praising those who continue to work for "life, the family, truth, peace, fraternity and justice."
