PHILADELPHIA (AP) — Seated on stage, Pope Francis is hearing from families from around the world and listening to musical performances at a festival hosted by the worldwide Catholic gathering that brought him to Philadelphia.

The pope is attending the World Meeting of Families festival Saturday, where he is meeting with families from the U.S., Australia, Ukraine, Jordan, Nigeria, and his homeland of Argentina.

An engaged Australian couple, Camillus O’Kane and Kelly Walsh, told the pope they are concerned about divorce and the push to change the definition of legal marriage.

The festival includes musical performances from Andrea Bocelli, Aretha Franklin and others. Actor Mark Wahlberg is the MC.

Francis will celebrate an outdoor Mass on the parkway Sunday in ending his first-ever U.S. trip.
