There’s been an unprecedented surge in the numbers of attendees at Sunday worship at the Quaker Arch Street Meeting House in Old City Philadelphia. Many of them are young people who are seeking respite from this noisy technological age in the silent worship of the centuries-old faith. For years, attendance at Arch Street was so low, and its historic 300-seat West Room felt so empty, that the few people present began to meet in a smaller room. But in recent years, they’ve used technology and social media to help teach others about Quakers and the meeting house that was built in the early 19th century and that is still one of the world’s largest and most important Quaker buildings.
