It would be hard to find a place on earth that better showcases the unity of the Catholic Church than here at World Youth Day. Hundreds of thousands of young people, all different, yet united by their faith, have gathered together here. Imagine a huge amount of Catholics coming together to worship at Mass. Now imagine them representing their countries with pride and talking about what faith is like back home. Finally, throw in a four mile beach that serves as the church. Ok, now stop imagining and watch it all right now!
