Disgust or horror is our natural attitude to eating human flesh and drinking human blood. How can this attitude not transfer itself to the Christian Eucharist, in which the bread is said to be Christ's body and the wine his blood? And if the aversion must transfer itself, then how can God have been, as Christians have to think, the founder of the rite? I discuss these questions with reference to several different theories of the Eucharist, one Calvinist, the others of a would-be Roman Catholic kind.
