A History of Christianity: The First Three Thousand Years

by Diarmaid MacCulloch

From the mid-twelfth century, a particularly persistent and pernicious community response to the occasional abuse and murder of children was to deflect guilt from Christians by blaming Jews for abducting the children for use in rituals. This so-called ‘blood libel’ frequently resulted in vicious attacks on Jewish communities. Sometimes higher clergy did their best to calm the community hysteria in such cases; sometimes they allowed shrine-cults of the murdered victims to develop. Recurrences of the blood libel persisted into the twentieth century as a blemish on Christian attitudes to Jews, spreading from the West into Orthodoxy in later centuries.
