One of the early accusations against Christians was that they were cannibals who practiced ritual human sacrifice and then devoured their victims in secret rites hidden away among the catacombs. If you’re familiar with the Christian sacrament of communion and its meaning, it’s easy to see how such a rumor could get started. The cup that Christians drink is a sharing in the blood of Jesus, and those who eat the bread are eating his body as well, at least according to the liturgy. The language and terminology they use is certainly the vocabulary of cannibals and vampires, and Christians attach great importance and reverence to that vocabulary. Small wonder, then, that some people took them for wanna-be cannibals and vampires.
