(M73) From this interesting passage we learn that the ancient Mexicans, even before the arrival of Christian missionaries, were fully acquainted with the theological doctrine of transubstantiation and acted upon it in the solemn rites of their religion. They believed that by consecrating bread their priests could turn it into the very body of their god, so that all who thereupon partook of the consecrated bread entered into a mystic communion with the deity by receiving a portion of his divine substance into themselves. The doctrine of transubstantiation, or the magical conversion of bread into flesh, was also familiar to the Aryans of ancient India long before the spread and even the rise of Christianity. The Brahmans taught that the rice-cakes offered in sacrifice were substitutes for human beings, and that they were actually converted into the real bodies of men by the manipulation of the priest. We read that “when it (the rice-cake) still consists of rice-meal, it is the hair. When he pours water on it, it becomes skin. When he mixes it, it becomes flesh: for then it becomes consistent; and consistent also is the flesh. When it is baked, it becomes bone: for then it becomes somewhat hard; and hard is the bone. And when he is about to take it off (the fire) and sprinkles it with butter, he changes it into marrow. This is the completeness which they call the fivefold animal sacrifice.”(242) These remarkable transformations, daily wrought by the priest, on the rice-wafer, were, however, nothing at all to those which the gods themselves accomplished when they first instituted the rite. For the horse and the ox which they sacrificed became a _bos gaurus_ and a gayal respectively; the sheep was turned into a camel; and the goat was converted into a remarkable species of deer, enriched with eight legs, which slew lions and elephants.(243) On the whole it would seem that neither the ancient Hindoos nor the ancient Mexicans had much to learn from the most refined mysteries of Catholic theology. (M74) Now, too, we can perfectly understand why on the day of their solemn communion with the deity the Mexicans refused to eat any other food than the consecrated bread which they revered as the very flesh and bones of their God, and why up till noon they might drink nothing at all, not even water. They feared no doubt to defile the portion of God in their stomachs by contact with common things. A similar pious fear led the Creek and Seminole Indians, as we saw, to adopt the more thoroughgoing expedient of rinsing out their insides by a strong purgative before they dared to partake of the sacrament of first-fruits.(244) We can now also conjecture the reason why Zulu boys, after eating the flesh of the black bull at the feast of first-fruits, are forbidden to drink anything till the next day.(245)
