The purpose of World Youth Day is threefold:

Putting Trust in the Young
World Youth Day is a coming together of young adults from the four corners of the world and a strong reminder of the strength and confidence the young bring to the Church today.

Gathering Together
World Youth Day is not simply a gathering for the young people of the world, but a time to put trust in the world's youth. A calling for the world's youth to come together as one people.

Meeting the International World on a Human Level
It is still a marvel in this the 21st Century to exchange with others and to be a part of an international experience. International events are able to stir much hope but also many fears (increase in fundamentalism, nationalism and other new conflicts. . .) The Church and Christians themselves have a role to play in preventing the development of these fears, and in aiding each person in finding their way and discovering hope.
