Palin's former pastor, Tim McGraw, says that like many Pentecostal churches, some members speak in tongues, although he says he's never seen Palin do so. Church member Caroline Spangler told CNN, "When the spirit comes on you, you utter things that nobody else can understand ... only God can understand what is coming out of our mouths."
Some Pentecostals from Assembly of God also believe in "faith healing" and the "end times" -- a violent upheaval that they believe will deliver Jesus Christ's second coming.
Most religious beliefs look "crazy" to outsiders, and suggestions that some are crazier than others are just a way of measuring how mainstream the religion is. What people want to do if they get in power matters, what they do on Sundays in their ideally private churches doesn't.
