A Catholic youth prays on her knees as her friends embrace her as the World Youth Day Cross is brought into a samba school in Rio de Janeiro, Brazil, July 20, 2013. The WYD symbol was given to young people of the church in 1983 by the architect of WYD, Pope John Paul II. Pope Francis will travel to Brazil and participate in WYD events from July 22-28.
