Twelfth-century Christian authors still read Jewish captivity as divine punishment for deicide
Evidence
When (for example) in book 2, the Jew explains that his people have been in captivity for the past twelve hundred years, the gentile responds that perhaps it is because the Jews have unwittingly sinned against God, a clear reference to the Christian notion that the destruction of the temple and the subjugation of the Jews was punishment for the killing of Christ. — John V. Tolan, Saracens, 1319
