At a Mass for the Jubilee of Youth outside Rome, Pope Leo exhorted over a million young people to be "seeds of hope" and a "sign that a different world is possible."

In his closing blessing for the Jubilee of Youth, Leo remembered the young people of Gaza and Ukraine and other countries at war who could not join their celebration.

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.
