Luther was used and abused and became senile at the end of his life. It was already too late for him to do anything about the Jews who used the reformation to destroy their number 1 enemy: the Jesuits, who were infiltrated by Marranos in the 16th century and an anti-coverso lobby was convened to bar any deemed Jewish member. Nevertheless, Jews continued to infiltrate the military order of the Church utilizing the reformation.

The Catholic Jesuits used the Blood purity laws as a way to prevent Jewish subversion, despite encyclicals denoting that Jewishness wasn't as much racial as it was a misanthropic, subversive ideology constructed by rabbis. Judaism and crypto-Judaism, were and are the causes of gentile backlash, as there are no redeeming qualities in Judaism whatsoever.

Neither Jew, nor Greek nor Roman in Christ. We renounce these designations and follow Christ. To relinquish Judaism as a Jew, is to relinquish being a Jew, thus that person is not a Jew. If a 'Christian' masonic cabalist Jew like Dr. Michael Brown, who convenes with the head f Mossad, says he's a 'Christian' Jew, he's not a Christian, he's a Jew.

As for Calvin, I can't post the sources right now, but, indeed, Calvin came from a marrano Jewish family and his father was friends with many Jewish merchants and cryptos.
