"It is evident that the Mesoamerican Indians, on being told of the Christian mass and being invited to take communion, expected the Host to be a great entheogen, perhaps superior to their own, in proportion as the European military, navigational, and metallurgical technology was superior to theirs. They were severely disappointed, and they immediately realized that the Eucharist was a placebo entheogen. Some of the Spanish choniclers from the sixteenth century noted the disquieting parallel between Christian Communion and the Indian Rites they were unable to perceive as the source of this Christian symbol."
