Everyone is invited to view a new painting commissioned especially for the 2015 World Meeting of Families as it is formally unveiled Sunday, Sept. 7 at the 6:30 p.m. Mass celebrated by Archbishop Charles Chaput at the Cathedral Basilica of SS. Peter and Paul in center city Philadelphia.

Called an “iconic image,” according to the Archdiocese of Philadelphia, it was painted by Kennett Square artist Neilson Carlin and will remain on display at the cathedral.

The archbishop will also lead the congregation, including local Catholic school students, in praying the official prayer for the World Meeting of Families and will comment on the prayer and painting during his homily.

The meeting is scheduled to welcome thousands of families from across the United States and the world Sept. 22-27, 2015, and perhaps be capped by a visit from Pope Francis. His possible attendance remains unconfirmed.

Organizers for the meeting are making updates available by cellphones. People can sign up for alerts by texting “World” to 51555. They can also donate to the effort by texting “PopeInPhilly” to 41444.

For those who cannot attend Sunday’s Mass at the cathedral, it will be streamed live on the World Meeting of Families website at worldmeeting2015.org and the Archdiocese of Philadelphia’s website at archphila.org.
