God is not a respecter of persons based on who their mother and father would be.
No man's relationship to God is now based on their DNA.
The verses found below prove this fact.
1Ti_1:4 Neither give heed to fables and endless genealogies, which minister questions, rather than godly edifying which is in faith: so do.
Tit_3:9 But avoid foolish questions, and genealogies, and contentions, and strivings about the law; for they are unprofitable and vain.
1Jn 2:22 Who is a liar but he that denieth that Jesus is the Christ? He is antichrist, that denieth the Father and the Son.
1Jn 2:23 Whosoever denieth the Son, the same hath not the Father: (but) he that acknowledgeth the Son hath the Father also.
What do we find in Romans?
Rom 9:8 That is, They which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed.
In the passage below Paul uses the Olive Tree as a symbol of the New Covenant Church made up of believing Israelites and believing Gentiles grafted together into the same tree.
Rom 11:1 I say then, Hath God cast away his people? God forbid. For I also am an Israelite, of the seed of Abraham, of the tribe of Benjamin.
Rom 11:2 God hath not cast away his people which he foreknew. Wot ye not what the scripture saith of Elias? how he maketh intercession to God against Israel, saying,
Rom 11:3 Lord, they have killed thy prophets, and digged down thine altars; and I am left alone, and they seek my life.
Rom 11:4 But what saith the answer of God unto him? I have reserved to myself seven thousand men, who have not bowed the knee to the image of Baal.
Rom 11:5 Even so then at this present time also there is a remnant according to the election of grace.
Rom 11:23 And they also, if they abide not still in unbelief, shall be graffed in: for God is able to graff them in again.
Rom 11:24 For if thou wert cut out of the olive tree which is wild by nature, and wert graffed contrary to nature into a good olive tree: how much more shall these, which be the natural branches, be graffed into their own olive tree?
Rom 11:26 And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob:
(The word "so" is an adverb of manner, instead of an adverb of timing. It refers back to verses 23 and 24.))
Rom 11:27 For this is my covenant unto them, when I shall take away their sins.
The ultimate form of "Replacement Theology" replaces the word "so", with the word "then" in Romans 11:26.
The "manner" of their salvation is by being grafted back into the Olive Tree through faith in Christ.
There is no Plan B outside of the New Covenant Church.
It replaces the New Covenant fulfilled for all races of people at Calvary, with a future covenant with the modern State of Israel in Romans 11:27.
It replaces the one seed, with the many seeds in Galatians 3:16.
The New Covenant promised to Israel and Judah in Jeremiah 31:31-34, which is found fulfilled by Christ during the first century in Hebrews 8:6-13, and specifically applied to the Church in Hebrews 12:22-24, and 2 Corinthians 3:6-8, destroys the Two Peoples of God doctrine.
In John 10:16 the Savior reveals there is only one people of God.
