Christian Roots of Nazism

Introduction
The content in this encyclopedia documents the Christian roots of Nazism. Some examples of Christian influence are in the personal history of the Nazis, and Christian antisemitism before and during medieval times and the post-medieval era, including the hatred of the Jewish people by the Church Fathers, the massacre in Rhineland in 1096, killings and mass forced conversions of the Jews to Christianity, and Martin Luther and his quotes from On the Jews and Their Lies in 1543.

Jewish deicide
Multiple biblical verses have influenced antisemitism, including the Jewish deicide charge that Jews as a people hold the responsibility for killing Jesus Christ. This claim led to the slur “Christ-killer” and the persecution of Jewish people, including massacres and forced expulsions of Jews from many countries. The deicide charge was a commonly held position among the Church Fathers and was the official position of the Catholic Church. The charge was made as early as the 2nd century by Justin Martyr and Melito of Sardis.

Church Fathers
The Church Fathers including Ambrose of Milan, Aristides of Athens, Augustine of Hippo, Eusebius of Caesarea, Gregory of Nyssa, Hippolytus of Rome, John Chrysostom, Justin Martyr, Melito of Sardis, Origen, Saint Ephraim, Saint Jerome, and Tertullian have made hateful remarks toward Jewish people, including blaming them for the death of Jesus Christ.

Papacy
The popes of the papacy have made laws restricting Jewish people, which includes Jews being prohibited from holding public office (1078, 1215, and 1442), prohibited from the construction of synagogues (1442 and 1555), prohibited from testifying against Christians (1442), forced to live in ghettos (1555, 1775, 1823, and 1850), forced to wear a Jewish badge and hat (1215, 1218, and 1555), and expelled from the Papal States (1569 and 1593). Pope Benedict VIII (1012-1024) ordered the execution of a number of Jews for alleged blasphemy against Jesus Christ.

The Inquisition established by Pope Gregory IX in the 13th century and lasted into the 19th century was used to suppress heresy. Officials of the Inquisition or inquisitors targeted suspected Jewish converts of Christianity that relapsed to Judaism. They were tortured and punished with death. Pope Paul IV (1555-1559) had ordered over twenty Marranos (Spanish Jews that converted to Christianity that were secretly practicing Judaism) to be burned at the stake in Ancona.

Killings
During the Crusades, Inquisition, and persecution of Jews during the Black Death, Jews were murdered by Christians. There were many other incidents of Christians murdering Jews and many have happened after blood libels (false allegations of Jews having killed Christian children for rituals) and accusations of host desecration.

Martin Luther
Martin Luther, a leading Christian of German Christian history, has made antisemitic statements, including advocating for the death of the Jewish people in On the Jews and Their Lies and Martin Luther's Table Talk.
