I just started a delightful book titled "Theology and Food" by Angel F. Mendez Montoya, a Dominican Friar. In it he makes the case that eating and and sacred awareness are intimately joined. He quotes from another work by David Carrazco, a meso-american scholar:
The Aztecs developed a sophiscated cosmology of eating in which gods ate gods, humans ate gods, gods ate humans and the sexual sin of humans, children in the underworld suckled from divine trees, gods in the underworld ate the remains of humans, and adults in the underworld ate rotten tamales!
Talk about Moctezuma's revenge!!!
