"It was a national, if not global, catastrophe which had a deep emotional impact on people," said Quinlan. "After a tragedy like that people tend to look upward. Our congregation in Queens saw a significant jump in attendance. We went from our average of about 175 people to around 225. That lasted for about four ... weeks after 9/11."
Quinlan wasn't the only pastor to see a spike in attendance.
Immediately after the attacks, attendance at religious services across the country increased 25 percent, according to a Barna Group report.
