A landmark history of the antisemitic blood libel myth—how it took root in Europe, spread with the invention of the printing press, and persists today.

Accusations that Jews ritually killed Christian children emerged in the mid-twelfth century, following the death of twelve-year-old William of Norwich, England, in 1144. Later, continental Europeans added a destructive twist: Jews murdered Christian children to use their blood. While charges that Jews poisoned wells and desecrated the communion host waned over the years, the blood libel survived.

Initially blood libel stories were confined to monastic chronicles and local lore. But the development of the printing press in the mid-fifteenth century expanded the audience and crystallized the vocabulary, images, and “facts” of the blood libel, providing a lasting template for hate. Tales of Jews killing Christians—notably Simon of Trent, a toddler whose body was found under a Jewish house in 1475—were widely disseminated using the new technology. Following the paper trail across Europe, from England to Italy to Poland, Magda Teter shows how the blood libel was internalized and how Jews and Christians dealt with the repercussions.

The pattern established in early modern Europe still plays out today. In 2014 the Anti-Defamation League appealed to Facebook to take down a page titled “Jewish Ritual Murder.” The following year white supremacists gathered in England to honor Little Hugh of Lincoln as a sacrificial victim of the Jews. Based on sources in eight countries and ten languages, Blood Libel captures the long shadow of a pernicious myth.

Focusing primarily on the Catholic doctrinal view of the Jews and its ramifications, Egal Feldman traces the historicalroots of anti-Semitism, examining tenacious Catholic beliefsincluding the idea that the Jews lost their place as the chosen people with the coming of Christianity, deicide, and the conviction that their purported responsibility for the Crucifixion justified subsequent Jewish misery.

A new era of Catholic-Jewish relations opened in 1962 with Vatican II’s Declaration on the Jews, reversing the theology of contempt. Feldman explores the strides made in improving relations, such as the Vatican’s diplomatic recognition of the Jewish state, as well as a number of recent issues.

In 1965 the Second Vatican Council declared that God loves the Jews. Before that, the Church had taught for centuries that Jews were cursed by God and, in the 1940s, mostly kept silent as Jews were slaughtered by the Nazis. How did an institution whose wisdom is said to be unchanging undertake one of the most enormous, yet undiscussed, ideological swings in modern history?

The radical shift of Vatican II grew out of a buried history, a theological struggle in Central Europe in the years just before the Holocaust, when a small group of Catholic converts (especially former Jew Johannes Oesterreicher and former Protestant Karl Thieme) fought to keep Nazi racism from entering their newfound church. Through decades of engagement, extending from debates in academic journals, to popular education, to lobbying in the corridors of the Vatican, this unlikely duo overcame the most problematic aspect of Catholic history. Their success came not through appeals to morality but rather from a rediscovery of neglected portions of scripture.

From Enemy to Brother illuminates the baffling silence of the Catholic Church during the Holocaust, showing how the ancient teaching of deicide—according to which the Jews were condemned to suffer until they turned to Christ—constituted the Church’s only language to talk about the Jews. As he explores the process of theological change, John Connelly moves from the speechless Vatican to those Catholics who endeavored to find a new language to speak to the Jews on the eve of, and in the shadow of, the Holocaust.

The forgotten history of American terrorists who, in the name of God, conspired to overthrow the government and formed an alliance with Hitler.

On January 13, 1940, FBI agents burst into the homes and offices of seventeen members of the Christian Front, seizing guns, ammunition, and homemade bombs. J. Edgar Hoover’s charges were incendiary: the group, he alleged, was planning to incite a revolution and install a “temporary dictatorship” in order to stamp out Jewish and Communist influence in the United States. Interviewed in his jail cell, the front’s ringleader was unbowed: “All I can say is—long live Christ the King! Down with Communism!”

In Nazis of Copley Square, Charles Gallagher provides a crucial missing chapter in the history of the American far right. The men of the Christian Front imagined themselves as crusaders fighting for the spiritual purification of the nation, under assault from godless Communism, and they were hardly alone in their beliefs. The front traced its origins to vibrant global Catholic theological movements of the early twentieth century, such as the Mystical Body of Christ and Catholic Action. The front’s anti-Semitism was inspired by Sunday sermons and by lay leaders openly espousing fascist and Nazi beliefs.

Gallagher chronicles the evolution of the front, the transatlantic cloak-and-dagger intelligence operations that subverted it, and the mainstream political and religious leaders who shielded the front’s activities from scrutiny. Nazis of Copley Square is a grim tale of faith perverted to violent ends, and a warning for those who hope to curb the spread of far-right ideologies today.
