Pope to pilgrims: spread faith as youth fest ends

Pope Benedict XVI urged more than a million young people to become missionaries for the faith Sunday, giving them words of encouragement as he concluded the church's youth festival and announced that the next edition will be in Rio de Janeiro in 2013.

Benedict told the crowd at a Madrid airfield hosting World Youth Day that they should not keep their faith private but participate fully in the life of their parishes and remain in communion with the church.

"So do not keep Christ to yourselves! Share with others the joy of your faith," he said.

Hours earlier, a fierce thunderstorm during a prayer vigil at the airfield had forced Benedict to cut short his remarks and slightly injured six people when a tent collapsed. Some makeshift chapels set up on the field's perimeter were also damaged, forcing organizers to announce Sunday morning over loudspeakers that not everyone would be able to receive Communion during the Mass.
