“Nor can I fail to offer heartfelt thanks to the young people for having come to the World Youth Day and for their joyful, enthusiastic and intense presence. To them I say thank you, and I congratulate you for the witness which you gave in Madrid and in the other cities of Spain in which you stayed. Now I ask you to spread throughout the world the profound and joyful experience of faith which you had here in this noble country. Share your joy especially with those who would have liked to come but were unable to do so for various reasons, with all those who were praying for you and with all those whose hearts were touched by these celebrations. By your closeness and your witness, help your friends to discover that loving Christ means living life to the full.”

— Pope Benedict XVI, speaking before departing Spain after World Youth Day, 21 August 2011
