Pope Leo celebrated the largest event yet of his nearly three-month tenure on Sunday, encouraging a crowd of more than a million Catholic young people gathered in a field on the outskirts of Rome to spread their faith.

The Pontiff celebrated the concluding mass of one of the most important events of the Holy Year. A million faithful filled the Tor Vergata esplanade in Rome. Pope Leo sent a message of hope for the young people afflicted by wars and recalled the words of his predecessor.

Hundreds of thousands of young faithful feted Pope Leo XIV like a rock star Saturday at an open-air prayer vigil outside Rome, after the head of the Catholic Church made a dramatic entrance by helicopter.
