What makes these two myths fascinating is the way they exemplify the splitting-and-projection that gives dualism its unique psychological hold. The Blood Libel is a Christian projection (that is not to say that Christianity embraced it or was responsible for it: recall the papal rejection of it). It makes no sense within the framework of Judaism. But it made sense to some believers in transubstantiation, the idea that the bread and the wine used in the Eucharist are not symbolically but actually the body and blood of the Son of God.
