Replacement Theology of Christianity, like that of Islam, undermines the very existence of the Jewish people, and the promises of God, relegating all of God’s commanded Biblical festivals (moedim) to irrelevance, and the trash heap of rejected Biblical doctrine, which is inherited from Rome.
A comment by a certain church leader is engraved in my mind, that today’s return of the Jewish people to Israel is a mere “political accident”, and Israel is not the Jews anymore but the “church”, which is the very essence of what led to the Inquisitions, the Crusades, the Expulsions, the Pogroms, and ultimately the Holocaust and other forms of Antisemitism unto this day, whose recipe was written by that great German Christian theologian, Martin Luther, among other Christian leaders before him.
These painful historical facts in the memory of the Jew continue to drive the Jewish people further from their Messiah.
Replacement Theology, which was spawned by the Roman Catholic Church nearly two millennia ago, was inherited by the Protestant Church, and unfortunately continues in some churches to this day.
Thankfully, many Christians have now rejected that theology. And despite that error of the misled, the God of Israel will have His way. We do not live in theological speculations, but reality.
I warn people against replacement theology every chance I have.
