Communion, or union with the deity, is an idea of great antiquity and has been common to all religions; although the methods practiced are numerous and varied. The more common mode, however, is by the consumption of consecrated foods and drinks, with the idea that these have acquired (by the act of consecration) a divine character of which the communicant becomes a partaker through their reception. The dogma of the eucharist was instituted many centuries before the Christian era and was believed in by the ancient Egyptians (from whom the Christians probably received it through the Alexandrian school), who, at the time of the celebration of the resurrection of Osiris, ate a sacred wafer, which, after consecration by a priest, was declared the flesh of the god. In ancient Greece, bread was worshiped as Ceres and wine as Bacchus; and, when the devout ate the bread and drank the wine, they claimed they were eating the flesh and drinking the blood of their deities. The ancient Mexicans used bread of corn meal mixed with blood, which, after, having been consecrated by the priests, was given to the people to eat as the flesh of Quetzalcoatl, much to the surprise and horror of the first Spanish missionaries, who ascribed it to mockery of their holy eucharist due to Satan. XII--THE EUCHARIST. The primal origin of the eucharist probably occurred far back in the period of universal anthropophagy. Most savage and semi-savage peoples have practiced cannibalism because they believed that by eating the flesh of the dead they gained the qualities of the deceased. Just as some Africans eat tiger to become brave, savages ate their courageous foes to attain their virtues. Following this same idea further, the belief was established that by consuming the flesh of a god, supernatural powers might be acquired. Thus the early Christian missionaries to the New World found such customs in Peru and Mexico. Father Acosta described one of these festivals which occurred annually each May in Mexico, wherein the statue of a god was made of dough, and "killed" by an arrow in the hand of a priest. The god was then broken in pieces which by means of "certain ceremonies ... were blessed and consecrated for the flesh and bones of this idoll." These pieces the priest gave "to the people in manner of a communion who received it with such feare, and reverence, as it was an admirable thing, saying that they did eate the flesh and bones of God." Likewise came the idea that sacrifices to the gods in some way attained godlike characteristics, and so the Guatemalan priests ate the bodies of the sacrificed.
