Here's more from the article in USA Today:
Among the 65% who call themselves Christian, "many are either mushy Christians or Christians in name only," Rainer says. "Most are just indifferent. The more precisely you try to measure their Christianity, the fewer you find committed to the faith."
Key findings in the phone survey, conducted in August and released today:
•65% rarely or never pray with others, and 38% almost never pray by themselves either.
•65% rarely or never attend worship services.
•67% don't read the Bible or sacred texts.
Many are unsure Jesus is the only path to heaven: Half say yes, half no.
"We have dumbed down what it means to be part of the church so much that it means almost nothing, even to people who already say they are part of the church," Rainer says. ...
Even among those in the survey who "believe they will go to heaven because they have accepted Jesus Christ as savior":
•68% did not mention faith, religion or spirituality when asked what was "really important in life."
•50% do not attend church at least weekly.
•36% rarely or never read the Bible.
Neither are these young Christians evangelical in the original meaning of the term — eager to share the Gospel. Just 40% say this is their responsibility.
Even so, Rainer is encouraged by the roughly 15% who, he says, appear to be "deeply committed" Christians in study, prayer, worship and action.
Collin Hansen, 29, author of Young, Restless, Reformed, about a thriving minority of traditionalist Christians, agrees. "I'm not going to say these numbers aren't true and aren't grim, but they also drive people like me to build new, passionately Christian dynamic churches," says Hansen, who is studying for the ministry. He sees many in his generation veering to "moralistic therapeutic deism — 'God wants you to be happy and do good things.' ... I would not call that Christianity, however."
