Which of the Scriptures in the post which proves that God established the New Covenant with Israel is false?

None! God does establish the new covenant with the house of Israel and Judah. Scripture is clear and consistent on this in both the old and new testaments.

Pauls words in Ephesians and Romans shows that he believed that gentiles become part of Israel, not physical Israel, but the Israel of God, and become partakers of those promises given to Israel.

If we're Christians we're under the new covenant and we now have hope and God in our lives...as Paul said.

[GiovannaNicoletta]

So if we know that God established the New Covenant with Israel, and not the Church since the Church wasn't around when the New Covenant was established, and we know from promises God made to Israel, and not the Church, in the New Covenant that have not yet been fulfilled but which require a literal, functioning nation of Israel for fulfillment, then we know that it is impossible that the Church is Israel.

Now, at this time, are you prepared to say that God was lying when He made His promises to the literal nation of Israel when the Church was thousands of years away from being established?
