I've never been fortunate enough to feel the power of healing hands, but I had a vet in Arkansas that demonstrated just that on my animals. Granted, he couldn't cure death, but it was amazing how much he could do, by just handling them. He was inarticulate with humans to the point of weirdness but he sure had something going with other animals. And there was no "faith" involved there, but the animals immediately quieted in his hands and often improved remarkably from only that.
