Enemies of Israel:

The church became the greatest enemy of Israel.

Reformers like Martin Luther, Zwingli, Calvin stirred hatred amongst the Christians towards the Jews. In 1500 AD Martin Luther suggested to his followers to burn all synagogues and Jewish Learning Centers and to demolish Jewish homes, to take away the Talmud and to stop rabbis to teach and demanded death on all rabbis. He demanded that all jewels and money be taken from them and suggested to put Jews into labour camps.
This was the start of anti-Semitism and evil, no love. This hatred was practiced all over the Continents in 1400-1500.
