For generations, the Jews in Europe suffered from the Christian church. Jew-hating priests incited their congregations against the Jews and Juadaism There was nothing they weren't willing to do in order to humiliate and persecute them.
At times, Hashem helped expose "justice-seeking" clergymen for what they really were: tricksters, swindlers, and bribe takers.
This story is based on the Sefer Hazichronos of the Rebbe Rayatz of Lubavitch. His sefer describes the tumultuous events of the times, and the persecution that the Jews underwent at the hands of the Vatican in Rome.
The events involve spies and corrupt tactics, a stark contrast to the Jews' dedicated activities and mesirus nefesh. It also describes a public debate between one Jew and thirty (!) Cardinals that ended with an overwhelming victory for Jews, Torah, and emunah in Hashem.
