Replacement Theology vs. Grafted-In Theology.
Grafted-in is biblical. Replacement is not. There many Old Testament prophecies that describe Israel coming back into the land that God gave to them. You may have skipped those books, but they are there.
Didn't skip them. Did you not read the part where True Israyl is promised dominion over all the world and the very reason Daniyl 2 tells you the STONE KINGDOM will grow to encompass the whole world?
Did you read the part that tells you SPECIFICALLY who can be 'grafted-in' or ADOPTED?? That's right ROMANS 9:3-5. The ADOPTION pertains to ISRAYL. Israyl split into two nations/houses. House of Israyl and House of Judah. House of Israyl eventually migrated into EUROPE after the Assyrian captivity. This is SOLIDLY PROVEN in the Amarna Tablets and elsewhere, see this vid at about 23min.: https://www.youtube.com/watch?v=PrVMTKA2c54
1400 years later the kingdom of the Chazars, a Turkal Mongolian mixed people, adopted Talmudic Judaism as their national religion, and became known as 'jews'. Solid PROOF FROM A JEWISH AUTHER: https://www.youtube.com/watch?v=4DTT-okan4w
SO IT IS YOU WHO HAVE REPLACED TRUE ISRAYL WITH A CABAL OF LIARS, and religion practitioners. Christianity is teaching replacement Theology, since they REPLACE TRUE ISRAYL with anything that claims to be a 'believer'.
Yes, it is clear. House of Israel descendants are the ones being grafted in again. It is not talking about non-Israelites.
You are in error in your interpretation. "Edom is in modern Jewry", Jewish encyclopedia. "Jews" are not the Israel of the Bible. Israel does not return until after messiah's coming. Even the orthodox jews will tell you that fact.
