At the World Youth Day celebration, Francis tells young people to imitate Christ through the 14 works of mercy.

July 31st is known around the world as Harry Potter's birthday.

Pope Francis walked alone, in silence and painful reflection, through the infamous Nazi concentration camp.

A merciful heart, Francis said, is one that “can welcome refugees and migrants.”

Francis spoke to more than 300,000 Poles at the famous shrine of the Black Madonna.

Francis said there is a need “for great wisdom and compassion” in addressing “the complex phenomenon of migration.”
