If instead of being a humble (but still very human) rural carpenter's helper offering the world's suffering His body and blood, this time He came back as a mere household pest.
Came back as that ever annoying blue green mold that ruins so much of our food and clothing.
Yes, as a 'fungoid growth', to paraphrase someone infamous.
And instead offering up His body and blood, this time the world's suffering and hurting got His poo and pee.
Because that is what the scientific consensus in that interwar period thought was the purpose of fungus secondary metabolites, like the life-saving penicillin - mere excretions of post-metabolic waste.
(Poo and pee, in words that even ankle-biters like Sam down at the daycare would understand.)
"J" as in Jewish or Jesus ?
The Double Miracle of penicillin "J".
In the face of Hitler's horror, a truly avenging Jewish Penicillin "J".
Saving lives and busting human hubris wherever it went.
Now of course many religious people think God is far too rational and level headed to do anything as hair-brained as that.
Myself, God is totally mysterious and free-spirited and loving and He just might.
For morally, for the most innocent of humanity-- its children, WWII was a truly desperate time, with the adult human ego and hubris on all sides of the conflict raging unchecked.
And desperate times do call for desperate (or at least inspired) measures....
