Catire Walker and Noel Zemborain and their four children had traveled 13,000 miles through 13 countries to attend the World Meeting of Families, joined hundreds of people at the gathering in helping to paint the mural that will eventually be permanently displayed at the future home of St. Malachy School in Philadelphia.
Carlos Martinez, director of records for Guinness World Records, certified the accomplishment.
Cesar Viveros, the Philadelphia muralist who designed the artwork, told the Catholic Review, newspaper of the Baltimore Archdiocese, that he was overwhelmed and surprised to see so many people contribute.
"Since this is the city of murals, it made total sense to make a mural as a monument for this special moment in history marking the pope's visit," he said. "It's very rewarding to know that people really care about building things together."
The art was commissioned by the World Meeting of Families and the City of Philadelphia Mural Arts Program. "The Sacred Now: Faith and Family in the 21st Century" was crafted from 153 panels measuring 5 feet by 5 feet.
In a morning news conference, Jane Golden, executive director of the Mural Arts Program, said the project achieved its goal of including people from many cultural backgrounds across the city, throughout the region and around the world.
"When this mural goes up in North Philadelphia, globally people can point to this and say, 'I helped create that,'" she said. "This work is beautiful, but it also has extraordinary meaning."
Working on the design, which features Pope Francis and diverse images of children, had a spiritual impact on the artist.
"It really revived me because at some point I was feeling a little bit down because I wasn't doing any more exciting projects," he told the Catholic Review, "and to have the chance to participate, I was very excited when I was called."
According to the Mural Arts Program, 330 gallons of mural paint will be used on the final project and 565 shades of color hand-mixed by the artist. The final mural will have more than 1.6 million brushstrokes applied.
On Sept. 26, during the Festival of Families in front of the Philadelphia Museum of Art, Pope Francis signed the last piece of the mural -- writing "Francis" in "nice big letters," said a news release from the Mural Arts Program.
