Some of our pioneers were cannibals. Some like the Donners out of necessity, some like the notorious Liver Eating Johnson, for totemic reasons as well as nutrition. And of course, there's Jeffery Daumer, a neighbor of mine in Philadelphia (never met him), who ate young men (literally). The ritual eating of the body and blood of The Christ is the sacrament of the eucharist in all Christian churches, to my knowledge, though it is really only bread and wine.
