National Israel does not even exist anymore. The only theological Israel that exists is spiritual Israel. You need to read and study Romans 11, particularly verses 25-36. The "Israel" that is the Bride of Christ is all believers, all who are in Christ. There are no bloodline limitations in Christ's Israel.
Gal 3:28 There is neither Jew nor Greek, there is neither slave nor free, there is no male and female, for you are all one in Christ Jesus.
I am not sure that the view that you have presented above that the Bride of Christ is physical Israel, wherein Gentiles are absent, is consistent with the rules of this forum. This is after all a Christian based forum. I think you need to be very careful.
You are incorrect.
On the day of the Jewish Feast of Harvest (Pentecost) circa AD 34, the Holy Spirit came down from heaven and three thousand Jews were born-again, baptized by the Holy Spirit into the body of Christ thereby inaugurating the birth of the Church Jesus promised to build, and natural Olive tree Israel became spiritual Olive tree Israel.
The Old Testament identifies Israel is betrothed to God thereby making Israel the Bride - NOT Gentiles.
Nowhere in the Old Testament does God call Gentiles His Bride or that He is betrothed to Gentiles. If that was true, then God has two women as His Bride and He is guilty of adultery. That's what it's called when a Husbandman gives marital love to a woman not His Bride. So, your argument that Gentiles is the Bride of Christ falls apart and fails. God is not an adulterer as you make Him out to be with your erroneous theology.
In Galatians 3:28-29 Saul is addressing Jews, NOT Gentiles. Now pay attention to the text.
23 But before faith came, we [JEWS]
were kept under the law, shut up unto the faith which should afterwards be revealed.
24 Wherefore
the law was our [JEWS] schoolmaster to bring us [JEWS] unto Christ, that we [JEWS] might be justified by faith.
25 But after that faith is come, we [JEWS] are no longer under a schoolmaster.
26 For ye [JEWS] are all the children of God by faith in Christ Jesus.
27 For as many of you [JEWS] as have been baptized into Christ have put on Christ.
What the next verse refers to is the concern - maybe worry - of Jews who were concerned with their standing as Abraham's seed because they were now followers of Christ.
28 There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye [JEWS} are all one in Christ Jesus.
29 And if ye [JEWS] be Christ’s, then are ye [STILL JEWS AND] Abraham’s seed, and heirs according to the promise.
Galatians 3:22–29.
Gentiles were never under the Law (3:23), Jews were. Saul calls the Law [our] "schoolmaster." Saul says that now that "faith" (the Holy Spirit) has come we [Jews] are no longer under a schoolmaster (the Law) and he means that in the way that we do not receive our righteousness by obeying the Law. Jesus taught that.
Saul, as rabbi and Pharisee is bringing up the prayer of Jews, but mainly the elders of the Sanhedrin which originally states, "I thank thee O' God that I was nor born a Greek [Gentile], or a slave, or a female", the epitome of subtle racist and misogynistic attitudes among Jews and their religious leaders. In one sentence Saul destroys that Jewish 'theology'.
Galatians has many references to the Law, Abraham, the prophets, their culture, and their religion, all these things the Gentiles are unconcerned with and are ignorant of. Saul is not saying the Law should not be obeyed because He commands Timothy and those with him that "All Scripture (Law and Prophets) is given by inspiration of God and is profitable for doctrine, reproof, correction, and INSTRUCTION IN RIGHTEOUSNESS so that the man of God be throughly furnished unto ALL GOOD WORKS." (2 Timothy 3:16-17.)
Not only that but Saul was a rabbi and remained a Pharisee and was obedient to the Law and was a man seen and received by Jews and elders of the Sanhedrin as a man of impeccable character and service to God:
Spoken of to Saul:
24 Them take, and
purify thyself with them, and be at charges with them, that they may
shave their heads: and all may know that those things, whereof they were informed concerning thee, are nothing;
but that thou thyself also walkest orderly, and keepest the law. Acts 21:23–24.
Saul makes this confession here:
14 But
this I confess unto thee, that after the way which they call heresy,
so worship I the God of my fathers, believing all things which are written in the law and in the prophets: Acts 24:13–14.
Or are you going to reject these truths I have posted above, reject the Word of God, and hold to your false Constantinian Gentile theology that lies about God and His Word.
Saul says, "
I believe all things written in the Law and the Prophets."
They say of Saul: "
but that thou thyself also walkest orderly, and keepest the law."
Do you reject this?
