Scratch the christian veneer of these teachers of replacement theology and you find real haters of the Jews--that is what drives their false theology.
Replacement Theology began in the Catholic church, and continued within the Protestant churches of the Reformation.
The RCC taught hatred for the Jews and tried to forcibly convert them to Christianity. Many pretended to become Christians, but retained their Jewish identity and beliefs. Many were persecute and slaughtered. And Martin Luther made no secret of his hatred for the Jews.
The Nazis took their lessons from Luther, and the Roman Catholic Church was an accessory to the crimes of the Nazis, as well as assisting them to escape to South America. The Dutch Calvinists were no better when it came to the treatment of the Jews.
But Replacement Theology is another BOGUS theology held by Reformed churches. Some Christians simply cannot accept the FACT that while God has an eternal plan for the Church (Jew and Gentile in one Body), He also has an eternal plan for redeemed and restored Israel on earth AFTER the Second Coming of Christ. Until then there no difference between Jew and Gentile in God's eyes. Yet, by His grace, He has preserved the modern secular nation-state of Israel, even though the majority of Jews within Israel are enemies of Christ (or at best indifferent to Him).
At the same time we can thank God that many former unbelieving Jews have become Messianic Jews by believing on
Yeshua ha Mashiach (Jesus the Christ). However, I do not believe that they are obeying Christ by isolating themselves from Gentile Christians, and attempting to revive Moses at the same time. They are facing the dilemma of the Hebrew Christians addressed in the epistle to the Hebrews.
