The Gospels of Jesus Christ accuses Israel as a Jewish nation that killed Jesus Christ. Official ruling and governent bodies, such as King Herod, tried to kill Jesus Christ, soon after He was born.
But also the Supreme Court of Israel, the Sanhedrin, ordered the death of Jesus Christ by using Jewish Law. This was an official court proceedings through the judicial system of Israel.
The Gospels is clear that Jesus Christ opposed the Jerusalem Temple and the Jewish nation of Israel. By His example, Jesus Christ taught that Christians MUST oppose the Jewish nation of Israel and support Christ the King who rejected the Jewish nation of Israel.
It is absolutely wrong for Christians in all Christian denominations to support the secular Jewish nation of Israel, because it is against the Gospel of Jesus Christ.
