Nowhere in scripture is the Church called the true Israel. I'm not a true Israelite. I'm in the body of Christ where there is no Jew or Gentile. We have not replaced Israel. They are still God's covenant people and He will fulfill His promises to that people at His 2nd Coming.
Galatians 3:7 7 Know then that it is those of faith who are the sons of Abraham.
Romans 9:6-8 6 But it is not as though the word of God has failed. For not all who are descended from Israel belong to Israel, 7 and not all are children of Abraham because they are his offspring, but “Through Isaac shall your offspring be named.” 8 This means that it is not the children of the flesh who are the children of God, but
the children of the promise are counted as offspring.
Who are the children of the promise? Note that this is addressed to a GENTILE church, and it says that they are children of the promise
Galatians 4:21-31 21 Tell me, you who desire to be under the law, do you not listen to the law? 22 For it is written that Abraham had two sons, one by a slave woman and one by a free woman. 23 But the son of the slave was born according to the flesh, while the son of the free woman was born through promise. 24 Now this may be interpreted allegorically: these women are two covenants. One is from Mount Sinai, bearing children for slavery; she is Hagar. 25 Now Hagar is Mount Sinai in Arabia; she corresponds to the present Jerusalem, for she is in slavery with her children.
26 But the Jerusalem above is free, and she is our mother. 27 For it is written,
“Rejoice, O barren one who does not bear; break forth and cry aloud, you who are not in labor! For the children of the desolate one will be more than those of the one who has a husband.”
28 Now you, brothers, like Isaac, are children of promise. 29 But just as at that time he who was born according to the flesh persecuted him who was born according to the Spirit, so also it is now. 30 But what does the Scripture say? “Cast out the slave woman and her son, for the son of the slave woman shall not inherit with the son of the free woman.”
31 So, brothers, we are not children of the slave but of the free woman.
Romans 2:25-29 For circumcision indeed is of value if you obey the law, but if you break the law, your circumcision becomes uncircumcision.
26 So, if a man who is uncircumcised keeps the precepts of the law, will not his uncircumcision be regarded as circumcision? 27 Then he who is physically uncircumcised but keeps the law will condemn you who have the written code and circumcision but break the law.
28 For no one is a Jew who is merely one outwardly, nor is circumcision outward and physical. 29 But a Jew is one inwardly, and circumcision is a matter of the heart, by the Spirit, not by the letter.
Philippians 3:3 3 For we are the circumcision, who worship by the Spirit of God and glory in Christ Jesus and put no confidence in the flesh—
Ephesians 2:11-22 Therefore remember that
at one time you Gentiles in the flesh, called “the uncircumcision” by what is called the circumcision, which is made in the flesh by hands— 12 remember that
you were at that time separated from Christ, alienated from the commonwealth of Israel and strangers to the covenants of promise, having no hope and without God in the world. 13 But now in Christ Jesus you who once were far off have been brought near by the blood of Christ. 14 For he himself is our peace, who has made us both one and has broken down in his flesh the dividing wall of hostility 15 by abolishing the law of commandments expressed in ordinances,
that he might create in himself one new man in place of the two, so making peace, 16 and might reconcile us both to God in one body through the cross, thereby killing the hostility. 17 And he came and preached peace to you who were far off and peace to those who were near. 1
8 For through him we both have access in one Spirit to the Father. 19 So then you are no longer strangers and aliens, but you are fellow citizens with the saints and members of the household of God, 20 built on the foundation of the apostles and prophets, Christ Jesus himself being the cornerstone, 21 in whom the whole structure, being joined together, grows into a holy temple in the Lord. 22 In him you also are being built together into a dwelling place for God by the Spirit.
Galatians 6:14-16 But far be it from me to boast except in the cross of our Lord Jesus Christ, by which the world has been crucified to me, and I to the world. 15
For neither circumcision counts for anything, nor uncircumcision, but a new creation. 16 And as for all who walk by this rule, peace and mercy be upon them, and
upon the Israel of God.
Note that Peter uses the same language used of ancient Israel in regards to the Church, and equates non-believers with Gentiles, and additionally he identifies them as those who were not a people:
1 Peter 2:9-13 But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light. 10 Once you were not a people, but now you are God's people; once you had not received mercy, but now you have received mercy. 11 Beloved, I urge you as sojourners and exiles to abstain from the passions of the flesh, which wage war against your soul. 12 Keep your conduct
among the Gentiles honorable, so that when they speak against you as evildoers, they may see your good deeds and glorify God on the day of visitation.
This is similar language that is used in regards to ancient Israel:
Exodus 19:4-6 4 You yourselves have seen what I did to the Egyptians, and how I bore you on eagles' wings and brought you to myself. 5 Now therefore, if you will indeed obey my voice and keep my covenant, you shall be my treasured possession among all peoples, for all the earth is mine; 6 and you shall be to me a kingdom of priests and a holy nation.’ These are the words that you shall speak to the people of Israel.
I have given you verses to prove the association of Israel with the Church. The Church is the fulfillment of the type of Israel. However, I think it's a little more than that. It was like the scaffolding of the building that was leading to the Church.
By the way, the word "assembly" in the OT, used to refer to the Church, is the same word in the Septuagint (Greek OT translation). It is the ekklesia of the OT, which means "the Church".
Additionally, as I have consistently maintained, the doctrine of union with Christ affirms that believers are spiritual Israel. Every believer is joined with Jesus, and shares in his inheritance. He is the true son of Israel.
Galatians 3:7-29 7 Know then that
it is those of faith who are the sons of Abraham. 8 And the Scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel beforehand to Abraham, saying, “In you shall all the nations be blessed.” 9 So then, those who are of faith are blessed along with Abraham, the man of faith. 10 For all who rely on works of the law are under a curse; for it is written, “Cursed be everyone who does not abide by all things written in the Book of the Law, and do them.” 11 Now it is evident that no one is justified before God by the law, for “The righteous shall live by faith.” 12 But the law is not of faith, rather “The one who does them shall live by them.” 13 Christ redeemed us from the curse of the law by becoming a curse for us—for it is written, “Cursed is everyone who is hanged on a tree”— 14 so that in Christ Jesus the blessing of Abraham might come to the Gentiles, so that we might receive the promised Spirit through faith. 15 To give a human example, brothers: even with a man-made covenant, no one annuls it or adds to it once it has been ratified.
16 Now the promises were made to Abraham and to his offspring. It does not say, “And to offsprings,” referring to many, but referring to one, “And to your offspring,” who is Christ. 17 This is what I mean: the law, which came 430 years afterward, does not annul a covenant previously ratified by God, so as to make the promise void. 18 For if the inheritance comes by the law, it no longer comes by promise; but God gave it to Abraham by a promise. 19 Why then the law? It was added because of transgressions, until
the offspring should come to whom the promise had been made, and it was put in place through angels by an intermediary. 20 Now an intermediary implies more than one, but God is one. 21 Is the law then contrary to the promises of God? Certainly not! For if a law had been given that could give life, then righteousness would indeed be by the law. 22 But the Scripture imprisoned everything under sin, so that the promise by faith in Jesus Christ might be given to those who believe. 23 Now before faith came, we were held captive under the law, imprisoned until the coming faith would be revealed. 24 So then, the law was our guardian until Christ came, in order that we might be justified by faith. 25 But now that faith has come, we are no longer under a guardian, 26 for in Christ Jesus you are all sons of God, through faith. 2
7 For as many of you as were baptized into Christ have put on Christ. 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. 29 And if you are Christ's, then you are Abraham's offspring, heirs according to promise. (ESV)
I don't know if many dispensationalists understand what the doctrine of union with Christ teaches, and how that impacts the promises given to Abraham. It doesn't seem like they understand it from the resistance I've encountered.
