Here's an interesting article about the history of communion wafers and how the production of them has changed over the years.
The difference is evident on the factory floor. The production plant at the Clyde, Missouri monastery, is adorned throughout with crucifixes and religious art, like a flour-dusted store-front church. Beneath Jesus on the cross, the nuns’ concentrated devotion recalls the Shaker cabinetmakers of the nineteenth century, sculpting the back of dresser drawers for His eyes only. The Cavanagh Co. does not have any religious ornaments in their production facility: in a factory constantly clouded with pulverized wheat, it would be inappropriate, Dan Cavanagh reasoned, “to put a cross up and have it essentially defaced with flour dust.” Cavanagh Co. retains a Christian sensibility, but what capitalist does not think his customers’ beliefs are sacred?
I can't believe people actually eat them for a snack. That's so wrong.
