It's been called the Catholic Woodstock. Hundreds of thousands of Pope Francis's youngest faithful, descending on Poland for this year's World Youth Day.
>> The Pontiff telling his followers to look beyond the instant gratification afforded by technology, and instead try to change the world. The clothes you wear or the kind of cell phone you use are of absolutely no concern, he says, and that God loves everyone. Francis peppered his sermon with social media and technology terms, appealing to the most wired generation in church history.
>> They came from all over the world and many had camped out overnight on the outskirts of Krakow, to hear the Pontiff speak. Sunday wrapped up a five-day tour of Poland, overshadowed by recent militant attacks across Europe, including the death of a Catholic priest in France on the eve of his trip.
Francis has said that the world is at war, but it is not a conflict caused by religion. This trip also brought him to the shrine of former Pope John Paul II, who was born in Poland. A children's hospital and the remains of the notorious Auschwitz concentration camp.
