In an only-in-America star-studded concert-as-prayer revival that shut down the iconic Benjamin Franklin Parkway Saturday evening, Sept. 26, Pope Francis asked families to give special care to children and grandparents. Children, the pontiff told a crowd on at least tens of thousands, are the future. Grandparents, he said, carry the "memory of the past." At the conclusion of an event that saw performances by Aretha Franklin, rock band The Fray and others, Francis spoke impassionately off the cuff for about 20-minutes. He repeated themes he has often addressed about family life.
