The hatred of the Jews by some people

I believe that in the past, there were some true believers that caused harm upon the Jews and there were non-believers that caused harm unto to the Jews, too.
The church should support the Jews and be their friends. Many Jews will be stubborn but the Born Again people needs to be patient with Israel.
The church of the Middle Ages from the 5th to the 19th Centuries had some bad history towards the Jews.
I believe that there were true believers and false believers that persecuted the Jews so many Jews think the cross of Jesus is anti-Semitic.
The true believers needs to realize this point so they need to pray and love the Chosen People.
If you like to read history, all these movement had anti-Semitic feeling in a small or great manner.
Here are the list if you like to read. The Romans Catholic Church; the Crusades, the charge of ritual murder, the abominable distinctive dress, Bernard of Clairvaux (1090-1153 A.D.), the Black Death of Europe (1447-1450 A.D.), Compulsory attendance at preaching sessions, the ghetto, the Spanish Inquisition and Expulsion of the Jews in 1492 A.D., the Chemlicki massacres from 1648 A.D. to 1658 A.D.
I hate to say this but Martin Luther was a great man of God but he started to hate the Jews during the Reformation. He did a lot of good work but being anti-Jew wasn't good.
And read about the Debates. Here are an long list of history that I am not going to brag to other people.
I believe reaching the Jewish people are hard because they are stubborn but the Holy Spirit can do great things.

Romans 11:1
I ask then: Did God reject his people? By no means! I am an Israelite myself, a descendant of Abraham, from the tribe of Benjamin.
