You keep forgetting about the New Covenant that your favorite Apostle of all times (Paul) allowed Gentiles to participate in as the Lord's Supper. Come out and say that you love Paul. Don't be shy.
Your Ethnic Cleansing spirit must be convulsing in sheer agony because of that fact. Tell us its name so that we can proceed with its exorcism.
We know that Samaritans were called "Samaritan" by Jews and not called Jews. Samaritans were the offspring of the Assyrian conquest of the ten northern kingdom tribes and their exile out of the Holy Land and into and among Gentiles and Gentile lands.
But what are the offspring of the two southern kingdom tribes called as a result of their conquest and exile to Babylon and in and among other Gentile lands? Where are they identified in the gospels of the letters (epistles)?
From 72q BC until the advent of Christ about 25-30 generations of Jews and mixed heritage Jews grew up without a nation in Gentile lands heavily influenced by Greek culture (Hellenized.) Then from 586 BC to Christ were about 15-20 generations of Jews and mixed heritage Jews who grew up in Gentile lands as Gentile heavily influenced by Greek culture. Where are these offspring of Judah and Benjamin with Gentiles through rape, concubinage, slavery, and forced or otherwise marriage to survive. Where are they mentioned in Scripture?
The New Covenant prophesied by Jeremiah 31:31-34 is only the Mosaic Covenant fulfilled by Christ. All Jeremiah does is prophesy the result and no mechanisms of covenant as is found in the Abraham Covenant and the Mosaic Covenant. The Abraham Covenant records what God is going to give, and Abraham's response as part of his responsibility is to circumcise.
The Mosaic Covenant records God giving the children of Israel His Law which covered every aspect of Hebrew life from social, moral, and ceremonial mechanisms and the only requirement from the children of Israel is obedience. The New Covenant doesn't have such descriptions of quid pro quo. All it records is what God will do absent any requirement from the House of Israel (ten northern kingdom tribes), and the House of Judah (two southern kingdom tribes.) Why is that? God requires nothing from the House of Israel and Judah in the New Covenant. Why is that?
No Jew, religious leaders, elders, even the common people would ever seek to circumcise a non-Hebrew Gentile nor to command a non-Hebrew Gentile to obedience to the Law of Moses. Why is that? Because all Jewry knows that the covenants were made with Abraham and with his seed and Gentiles do not come from Abraham's seed. BNUT if a person is the offspring of Jew-Gentile intermingling they are still Abraham's seed and heirs according to the Promise. Saul, Peter, James, John, none of the Jews and Jewish Christians would ever seek to do those things upon non-Hebrew Gentiles. They are NOT the seed of Abraham. Saul knows this. He would never seek to circumcise a non-Hebrew Gentile nor to cause a non-Hebrew Gentile to obey the Law of Moses, something he still did after meeting the Lord on the Damascus road and he was held in high esteem by the Jews and the religious leaders as well.
Fact #1. The Abraham and Mosaic Covenants are between God, Abraham, and Abraham's seed and non-Hebrew Gentiles are not the seed of Abraham. They are the seed of Japheth and Ham.
Fact #2. If Jewish Christians (Saul, Peter, James, John, etc.), were to actually seek to circumcise and non-Hebrew Gentile (a Jew would know what this would mean), or to order or cause a non-Hebrew Gentile to obedience to the Law of Moses this would be vilation of the Law because all Jews know that non-Hebrew Gentiles are NOT included in the Law.
Fact #3. Under the Law the high priest would sacrifice an animal yearly on Yom Kippur to atone for the sins of the children of Israel. There is no Scripture the high priest did this for non-Hebrew Gentiles.
Fact #4. Jesus fulfilled every precept of the Law of Moses. In keeping with the Law of Moses Jesus Christ, as High Priest, died and resurrected to atone finally and eternally for the sins of the children of Israel. Jesus KEPT the Law, a Law that did not include non-Hebrew Gentiles.
Fact #5. The New Covenant is, as Jeremiah prophesied, is between God and the House of ISRAEL and the House of JUDAH, thus covering all twelve tribes of Israel.
This is why Saul wrote this truth:
4 But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law,
5
To redeem them that were under the law, that we might receive the adoption of sons.
Gal. 4:4–5.
