Hundreds of thousands of young Catholics poured into a vast field on Rome’s outskirts Saturday for the weekend highlight of the Vatican’s 2025 Holy Year: an evening vigil, outdoor slumber party and morning Mass celebrated by Pope Leo XIV that marks his first big encounter with the next generation of Catholics.

Let us hope that all of you will always be a sign of hope for the whole world,' said the Holy Father, this time speaking in Italian.

Pope Leo XIV on Tuesday received a rock star's welcome at the Vatican's festival of Catholic influencers — priests, nuns and ordinary faithful who use their social media presence to preach and teach the faith — as he urged them to ensure that human relations don’t suffer with the spread of digital ecosystems and artificial intelligence.
