ROME, Italy — In a remarkable demonstration of faith and unity, close to one million young pilgrims from 146 countries convened in Rome’s eastern suburbs for the Jubilee of Youth, marking an important milestone in Pope Leo XIV’s early days as the leader of the Catholic Church.

The event began with a dramatic helicopter arrival that ignited cheers and tears among the crowd, as the pope made his way through the sea of young faithful waving from his popemobile. Organizers estimated attendance around 800,000, with some projections nearing a million participants.

During the day, attendees endured the heat, engaging in musical performances, prayer sessions, and fellowship. As the sun began to set, the atmosphere shifted to a more reflective tone when Pope Leo XIV, aged 69, appeared on stage carrying a large wooden cross. He addressed the crowd saying, "Dear young people, after walking, praying and sharing these days of grace of the Jubilee dedicated to you, we now gather together in the light of the advancing evening to keep vigil together."

The vigil, described by some as a Catholic "Woodstock," featured nearly two dozen religious music and dance groups, enhancing the celebrations across the vast open area equivalent to about 70 football fields.

Pilgrims like 18-year-old French attendee Julie Mortier expressed overwhelming joy, calling the opportunity to see the pope a once-in-a-lifetime experience. British student Andy Hewellyn shared similar sentiments, emphasizing the importance of communal spirit despite being far from the stage.

The week-long pilgrimage, which began earlier in the week, leads up to a closing mass on Sunday morning, to be presided over by the pope. Many attendees planned to camp overnight, ready to continue their spiritual journey.

Amidst the celebrations, some moments of somber reflection occurred. The pope met with travelers accompanying an 18-year-old Egyptian pilgrim who recently passed away. The event also highlighted the Church’s recognition of the challenges youth face globally, including economic hardship, climate change, and conflict, as many pilgrims had traveled from crisis-impacted regions such as Syria, Ukraine, and Belize.

Notably, confessions were offered throughout the week at historic locations like the Circus Maximus, staffed by thousands of priests facilitating spiritual reconciliation.

Italian Prime Minister Giorgia Meloni sent a video message welcoming the pilgrims, praising the vibrant spirit of prayer and celebration.

Security for the massive gathering was robust, with over 4,300 volunteers and more than 1,000 police officers ensuring the safety of the participants.

The Jubilee of Youth not only underscored Pope Leo XIV’s connection to the younger generation but also reaffirmed the Catholic Church’s commitment to inspiring hope and community among global youth during challenging times.
