The World Meeting of Families is a gathering of Catholic families that takes place every three years.

Francis will arrive in Philadelphia on Sept. 25. Two days later, he will hold a public mass that officials expect up to 2 million people to attend, according to NBC Philadelphia.

The new pope has taken a different approach from predecessors by signaling an openness to gays and lesbians, saying in one interview, “Who am I to judge?” He has also spoken out against income inequality and looked to broaden the church’s reach.

He has drawn criticism from some in the conservative wing of the church who have perceived statements as a loosening of doctrine.

As his profile has risen around the world, some in America have looked to bring Francis stateside. Earlier this year, House Speaker John Boehner (R-Ohio) invited him to speak to a joint session of Congress.
