The idea that Jesus scholar Crossan has anything substantive to say about wartime penicillin would come as a surprise to most people , John Dominic Crossan most prominent among them.
But if one regards the sheer amount of resistance medical orthodoxy put up (for twenty wasted years) against the idea of injecting native penicillin into dying patients , one can see the application of Crossan's concept of 'magician healing' : which he regards as all healing that lies outside outside the orthodoxies of the day, medical or otherwise.
Jesus's healing being his prime but by no means only example.
We never did get commercial white man-made penicillin : all the penicillin during WWII and ever since has been grown naturally , natively, by tiny yeast like beings.
Virtually all of our antibiotics are still mere modified versions of WWII's original native penicillin.
Medical orthodoxy today swears by native penicillin and all its life saving derivatives.
Mea culpa is more a word Jesus would use than one many MDs are comfortable using --- but would it really hurt - just this once - to admit that the elders of their profession got it 180 degrees wrong back then in the darkest days for humanity, infected or otherwise .....
