I in fact do know; it will be in Rio de Janeiro, Brasil (July 21-29, 2013).
Here is the theme:
Go and make disciples of all peoples. (Matthew 28:19)
The websites I have found are not yet very useful (I bet that in a year they will be though), so any information I have is limited to the above
I'll be looking at the Rio de Janeiro diocese website to have a trustworthy source as time goes on. I don't know much Portugese, but I can pick up on key words. If it's anything like the Madrid diocese website, then they will eventually have a link to the official website for WYD 2013 (which will be available in English).
Are you thinking of going? Or are you hoping someone you know will go?
I'm currently in California so it's still night for me
I really wanted to go to WYD 2011, but I guess GOD had different plans for me (or maybe I didn't listen to His plan?).
Hopefully I'll be able to go to the next one in 2013 with my sister (I'll be a little older by then though but I'm sure plenty of people will still see me as "youth" )
