Which Replacement Theology, are you referring too?
The standard definition of Replacement Theology unless there's another that I'm not aware of.
This is the theory that we (believing Gentiles) are the new Israel and that God has washed his hands of the Jews and all the promises made to the Jews have been passed onto us. I'm not sure where it originated but the Roman Catholic Church dabbled in it for a while. It is used today by anti-Semites, Israel-haters and various other groups that call themselves Christian. However the theory is destroyed by various bits and pieces of scripture namely Romans 11 and a selection of OT verses.
Replacement Theology also destroys itself because it infers that God is a liar who cannot be trusted because fulfillment of prophecy is dependent on the Jews. If this promise to the Jews is broken then God could easily break his promises to us.
Before I try to discuss this with you, do you completely understand all this,
that I have quoted from the new testament, that is which was recorded by some of the Apostles,
as the words of Jesus Christ?
I understand they are quotes, yes.
They are the Words of God.
