Pope Francis encouraged young Catholics to get out of their parochial boundaries in order to help others.
"Go and don't be afraid of serving," he said.
"Jesus did not gather the Apostles so they lived in isolation. He called them so they formed a group, a community," said Pope Francis.
He announced the next Catholic youth festival would be held in the Polish city of Krakow in 2016
