Until the establishment of the USA, Christians and Muslims have been trying to rid the world of the Jews, and each other, as well as those within their ranks who were deemed to be heretics. They almost succeeded in the 1940s of ridding the world of we Jews.
The Muslims are still working on it.
Critically, during WW II, Pope Pius XII and the Catholic Church saved some 860,000 Jews from the Nazis -- more than all other international agencies put together. Catholic church buildings in Rome -- including the Papal residence outside the city -- were jammed full with Jews in hiding. After the war, the Chief Rabbi of Israel thanked Pius XII for what he had done, while the Chief Rabbi of Rome became a Catholic and adopted the name Eugenio, Pope Pius's given name at birth.
Through Israel's Yad Vashem, many thousands of Christians are formally recognized as Righteous Among the Nations for saving Jews from the Nazis. Polish diplomat and patriot Jan Karski -- who was married to a Jew -- was smuggled into Aushwitz and then sent by the Polish Home Army to the US to provide the first irrefutable direct account of the Holocaust to the American public.
I could go on, but will instead leave the abundant sources to your own exploration.
It is simply false — and absurdly false at that — to claim that Christians were trying to “rid the world” of Jews and competing Christian sects.
