Marz Haney grew up faithfully attending an Evangelical church every weekend with her family. These days, the 21-year-old skips Sunday morning worship, often drinking coffee with her roommate at Bob's Java Hut in Minneapolis instead.
"I wouldn't call myself an atheist, but I'm not interested in being part of a church," said Haney, who stopped going to church in college. "I had some doubts all along. I was sort of in continual doubt about my personal salvation."
With her deep reservations about organized religion, Haney is part of a rapidly growing group of Americans not claiming any faith. They're called the "nones." They have toppled the nation's Protestant majority for the first time in U.S. history and are forcing religious leaders to do some soul-searching.
The unprecedented findings by the Pew Forum on Religion & Public Life show that about 20 percent of adults -- about 46 million -- have no religious affiliation, up from about 15 percent just five years ago.
"That's quite significant," said Scott Thumma, a researcher at the Hartford Institute for Religious Research in Connecticut. "It has to do with the erosion of it being the acceptable practice to go to church on Sunday. If you don't break that cycle, there's going to come a time in not too many generations when 60, 70 percent of people are going to say, 'This is completely irrelevant. It's not something that adds any sense of meaning to my life.'"
'Not looking for a religion'
The "nones" include more than 13 million atheists and agnostics and some 33 million adults who say they have no religious affiliation. About a third of U.S. adults under age 30 are unaffiliated.
"Nones" are "not looking for a religion that would be right for them. Overwhelmingly, they think that religious organizations are too concerned with money and power, too focused on rules and too involved in politics," the study states. Many believe in God and say they're "spiritual," but not "religious."
