What happens in the bible not exactly healing. As a science-based person, religious claims of magical healings drive me nuts. Like Astreja and many others here, I get so tired of religions giving prayer and gods the credit for the hard work and dedication of scientific researchers, doctors, dentists, surgeons, nurses, pharmacists, technicians and on and on.
Jesus did not heal anyone. Because Jesus never performed any examination or made a diagnosis.
Someone shows up describing what appears to be a health problem and Jesus somehow, magically, makes the problem go away. No control groups of people with the same symptoms to see if they also got better, even without any interaction with Jesus. There is no explanation other than he is Jesus, he is really special, and sometimes he is able to heal people. He does not even have to know he is healing someone. Just being near him is enough. Jesus does not have to lay hands or pray to god to heal people-- he is like the Chuck Norris of making people better.
Example: I remember this one from my early teen years (understandably) the story of the woman with the non-stop menstruation. She touched Jesus' robe and the bleeding magically stopped. But why was she bleeding?
It matters, because different causes would require Jesus to magically manipulate different cells or whatever in the woman's body. How old was she? Did she have cancer of the uterus or cervix? Endometriosis? Fibroids? Did Jesus do a heavenly hysterectomy? A divine D and C? Or what? We do not know if the condition was actually cured or healed because we do not know what was wrong, or what Jesus did.
We are only told that the symptoms were alleviated. There are no follow-up visits to see if the symptoms came back, or if the lady died a month later of the same thing.
If you look at the history of medicine, the "healings" of Jesus exactly match the non-spiritual, non-magical medical treatments of the era before modern scientific medicine. People had no way of looking inside the body with x-rays or doing any type of tests to see what was actually wrong. Dissection of the dead was not allowed in many societies. Medicine-- with a few exceptions like the medieval Muslims who did some scientific investigations--was flying blind.
Practitioners, midwives, shamans and healers treated symptoms with whatever they had to hand, and were mostly relying on the placebo effect of doing something rather than nothing. By using trial and error, preparations of precious stones or metals, herbs that worked on animals, "like treats like" and so on, some people got better.
If the symptoms went away, the person was cured.
That is why the most effective popular medicines of ancient times were narcotics like opium or depressants like wine. In small amounts, they did little harm and sometimes did good. This was stuff that quieted coughs, made people feel better, calmed people down and basically made people go to sleep. Rest, allowing the body to fight infection and repair itself, is often the best thing for many illnesses. Especially if you can't really diagnose or cure the underlying condition.
Here is what is telling and leads me to think that if there really was a Jesus who did some healings, they were not really miracles. They were at best, harmless placebos and at worse, shameful trickery like "psychic surgery".
Jesus did not cure all
people with leprosy. That would have been a miracle. He cured one leper.
That could have been a trick. He did not heal all women with bleeding. That would have been a miracle. He cured one woman.
That could have been a trick. He did not heal all amputees. That would have been a miracle.He put one guy's ear back on.
That could have been a trick.
Jesus did not eliminate all smallpox or all cancer or all of anything. That would have been impossible to fake or lie about. That would have been different from all previous faith healers. That would have made news all over the world, as smallpox disappears from Africa, China and Europe the same day as Jesus heals it in the Middle East.
So, a big negatory on the Jesus healings.
