Paul also distinguished between the Church, Israel and the Gentiles (1 Cor 10:32).
In Romans 9:2-5, he defines the term "Israel"
Rom 9 NIV
2 I have great sorrow and unceasing anguish in my heart. 3 For I could wish that I myself were cursed and cut off from Christ for the sake of my people, those of my own race, 4 the people of Israel. Theirs is the adoption to sonship; theirs the divine glory, the covenants, the receiving of the law, the temple worship and the promises. 5 Theirs are the patriarchs, and from them is traced the human ancestry of the Messiah, who is God over all, forever praised! Amen.
In Romans 11, especially verses 25 to 29, it is clear that Paul thinks Israel separate from the Church, as using the terms interchangeably makes zero sense.
Rom 11 NIV
25 I do not want you to be ignorant of this mystery, brothers and sisters, so that you may not be conceited: [the Church] has experienced a hardening in part until the full number of the Gentiles has come in, 26 and in this way all [the Church] will be saved. As it is written:
“The deliverer will come from Zion;
he will turn godlessness away from Jacob.
27 And this is my covenant with them
when I take away their sins.”
28 As far as the gospel is concerned, [the Church] are enemies for your sake; but as far as election is concerned, [the Church] are loved on account of the patriarchs, 29 for God’s gifts and his call are irrevocable.
Some questions I have with your view:
1) Can you please elaborate on how the Church has experienced a hardening in part? When, why and how did this hardening happen?
2) What happens when the Church's hardening is dispelled? (v. 25) The entire Church is saved in the future? I thought they already had their sins taken care of.
3) How is the Church enemies with the Church as far as the gospel is concerned (v. 28)??? How is the Church loved on account of Abraham, Isaac and Jacob?
4) didn't Jesus say "
I will build my Church" (Mt. 16:18)? Doesn't that make the Church a future entity after the earthly ministry of Jesus?
How? Why?
This is why I don't think anything I say to you will matter. You don't know up from down and can't follow a convo/discussion.
