I think healings take place from time to time by the intercession of lay people. God hears all prayers, and if He chooses to heal someone in response to someone’s prayer, then so be it. I’m suspicious of the Benny Hinn type spectacle, but at the same time I’ve got an open mind regarding miraculous healing. It happens from time to time.
I’ve got a book on my shelf about a bloke called Brother Yun. He was a Christian in China, and had his legs smashed by the police for escaping from jail. Yet about six weeks later, he had the dual mriacle of his legs instantaneously healing and literally walking out of a high security jail.
But he’d suffered a great deal prior to that. He is not Catholic, but his witness for Christ is very real.
Miraculous healings happen. And they don’t necessarily require the intercession of a Catholic priest. Paul wrote about laying on of hands, and he wasn’t writing to Catholic priests or bishops, as at that time they didn’t even exist. On the other hand, I haven’t got much trust in the hype of some of the more vocal televangelists. I don’t think their healings would stand up to prolonged scrutiny in most cases.
