THE WILLING VICTIM:
"Just as the animal of the hunter, the animal that is the principal animal of his life, becomes the animal master, who when planting comes in, the main plants are sanctified also... Our whole life is sustained by the mystery life, and everything that you eat, whether vegetable or animal, is a life that is being given to you through its own willingness to become your own life substance." -- Joseph Campbell
What we worship depends on how we live. The hunter-gatherers of North America found divinity in bears, eagles and buffalo. Further south where vegetation dominated the landscape, plants were a source of divinity. The Huichol Indians of Mexico consume peyote as a sacrament. In Oaxaca, Mexico the Ololiuqui or Morning glory was taken for the same purpose. Among the Aztecs, Teonanacatl, or the sacred mushroom was revered.
In each case the sacrament is, metaphorically, the flesh of the gods. ("Verily, verily, I say unto you, except ye eat the flesh of the Son of Man and drink his blood, he have no life in you." --Jesus) The plants and animals give of themselves to the people so that they may have life and that they may have it more abundantly.
Each plant, each animal had specific attributes, and ingesting them invested in the recipient the power of that which was consumed.
In short, you are what you eat. The taking of a sacrament is a ritual act by which the worshiper places his mind and body in accordance with the deity. The two come into union.
Who are our deities? What is our sacrament? Coke and popcorn, blood and body, taken in remembrance of cinematic saviors lighting a controlled darkness where death cannot enter.
