You said, “Our Lord called us sons of Abraham and of the Father, Paul called us the new Israel, and Peter called us a royal priesthood. These, and many other titles, are given to those who believe in the Lord Jesus. We are Israel-regardless of how much people try to spin this. To think otherwise borders on blasphemy in my opinion.”
Yes, we are sons of Abraham by faith.
Yes, we Gentiles who believe are described as a wild olive, grafted in to the olive tree, Israel (Romans 11). But to say that the church = Israel is not quite the whole truth.
Not only are the Gentiles sons of Abraham by faith, but so are the Jews who believe God through faith. There is only ONE true Son and that is the Lord Jesus. Everyone else is adopted into God's kingdom.
