Israel-Only claims that the Gentiles had to be circumcised in the past but then became uncircumcised later on before Christ came. They say that a Gentile who was never circumcised in the past, was not eligible for salvation.
Therefore, they are in effect, requiring the salvation by works. They completely miss the point of what Jesus did on the cross.
In the old covenant of Israel, the Gentile was outside the covenant if they were not circumcised – this includes BOTH those who were born uncircumcised and who deconverted by being physically removing a past circumcision. All Gentiles were CUT OFF from the covenant unless they became circumcised.
“9 Then God said to Abraham, “As for you, you must keep my covenant, you and your descendants after you for the generations to come. 10 This is my covenant with you and your descendants after you, the covenant you are to keep: Every male among you shall be circumcised. 11 You are to undergo circumcision, and it will be the sign of the covenant between me and you. 12 For the generations to come every male among you who is eight days old must be circumcised, including those born in your household or bought with money from a foreigner—those who are not your offspring. 13 Whether born in your household or bought with your money, they must be circumcised. My covenant in your flesh is to be an everlasting covenant. 14 Any uncircumcised male, who has not been circumcised in the flesh, will be cut off from his people; he has broken my covenant.”
Some Israel-Only folks say that a person had to be physical descendant of Abraham. But later on we see pagans from Persia who joined Israel by circumcision (they became Jews)
“16 For the Jews it was a time of happiness and joy, gladness and honor. 17 In every province and in every city to which the edict of the king came, there was joy and gladness among the Jews, with feasting and celebrating. And many people of other nationalities became Jews because fear of the Jews had seized them.”
So therefore in the old covenant, righteousness/salvation was given by those who OBEYED the WORKS of the LAW (Circumcision, etc)
Moses said that here:
Romans 10 “5 Moses writes this about the righteousness that is by the law: “The person who does these things will live by them.”
But then Paul wrote to the Gentiles in Rome that Christ came to end the law so that righteousness was now given by faith to ALL who believe:
Romans 10 ”
Christ is the culmination of the law so that there may be righteousness for everyone who believes. 5 Moses writes this about the righteousness that is by the law: “The person who does these things will live by them.” 6 But the righteousness that is by faith says: “Do not say in your heart, ‘Who will ascend into heaven?’” (that is, to bring Christ down) 7 “or ‘Who will descend into the deep?’” (that is, to bring Christ up from the dead). 8 But what does it say? “The word is near you; it is in your mouth and in your heart,” that is, the message concerning faith that we proclaim: 9 If you declare with your mouth, “Jesus is Lord,” and believe in your heart that God raised him from the dead, you will be saved. 10 For it is with your heart that you believe and are justified, and it is with your mouth that you profess your faith and are saved. 11 As Scripture says, “Anyone who believes in him will never be put to shame.” 12 For there is no difference between Jew and Gentile—the same Lord is Lord of all and richly blesses all who call on him, 13 for, “Everyone who calls on the name of the Lord will be saved.”
This is why Paul told the Gentiles in Ephesus that salvation is BY GRACE and NOT WORKS. What was the works in question? It was circumcision. So then Paul was telling these Gentiles this: Jesus Christ died on the cross and ended the law and all it’s commandments (circumcision, etc) so that Gentiles could now become saved/righteous by GRACE without works but simply by FAITH.
Ephesians 2 ”
As for you, you were dead in your transgressions and sins, 2 in which you used to live when you followed the ways of this world and of the ruler of the kingdom of the air, the spirit who is now at work in those who are disobedient. 3 All of us also lived among them at one time, gratifying the cravings of our flesh and following its desires and thoughts. Like the rest, we were by nature deserving of wrath. 4 But because of his great love for us, God, who is rich in mercy, 5 made us alive with Christ even when we were dead in transgressions—it is by grace you have been saved. 6 And God raised us up with Christ and seated us with him in the heavenly realms in Christ Jesus, 7 in order that in the coming ages he might show the incomparable riches of his grace, expressed in his kindness to us in Christ Jesus. 8 For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God—9 not by works, so that no one can boast. 10 For we are God’s handiwork, created in Christ Jesus to do good works, which God prepared in advance for us to do.
11 Therefore, remember that formerly you who are Gentiles by birth and called “uncircumcised” by those who call themselves “the circumcision” (which is done in the body by human hands)— 12 remember that at that time you were separate from Christ, excluded from citizenship in Israel and foreigners to the covenants of the promise, without hope and without God in the world. 13 But now in Christ Jesus you who once were far away have been brought near by the blood of Christ.
14 For he himself is our peace, who has made the two groups one and has destroyed the barrier, the dividing wall of hostility,15 by setting aside in his flesh the law with its commands and regulations. His purpose was to create in himself one new humanity out of the two, thus making peace, 16 and in one body to reconcile both of them to God through the cross, by which he put to death their hostility.17 He came and preached peace to you who were far away and peace to those who were near. 18 For through him we both have access to the Father by one Spirit.
19 Consequently, you are no longer foreigners and strangers, but fellow citizens with God’s people and also members of his household,20 built on the foundation of the apostles and prophets, with Christ Jesus himself as the chief cornerstone.21 In him the whole building is joined together and rises to become a holy temple in the Lord. 22 And in him you too are being built together to become a dwelling in which God lives by his Spirit.”
Paul said that Abraham was made righteous before circumcision – therefore righteousness is given by faith without circumcision.
What then shall we say that Abraham, our forefather according to the flesh, discovered in this matter? 2 If, in fact, Abraham was justified by works, he had something to boast about—but not before God. 3 What does Scripture say? “Abraham believed God, and it was credited to him as righteousness.”
4 Now to the one who works, wages are not credited as a gift but as an obligation. 5 However, to the one who does not work but trusts God who justifies the ungodly, their faith is credited as righteousness. 6 David says the same thing when he speaks of the blessedness of the one to whom God credits righteousness apart from works:
7 “Blessed are those
whose transgressions are forgiven,
whose sins are covered.
8 Blessed is the one
whose sin the Lord will never count against them.”
9 Is this blessedness only for the circumcised, or also for the uncircumcised? We have been saying that Abraham’s faith was credited to him as righteousness. 10 Under what circumstances was it credited? Was it after he was circumcised, or before? It was not after, but before! 11 And he received circumcision as a sign, a seal of the righteousness that he had by faith while he was still uncircumcised. So then, he is the father of all who believe but have not been circumcised, in order that righteousness might be credited to them. 12 And he is then also the father of the circumcised who not only are circumcised but who also follow in the footsteps of the faith that our father Abraham had before he was circumcised.
13 It was not through the law that Abraham and his offspring received the promise that he would be heir of the world, but through the righteousness that comes by faith. 14 For if those who depend on the law are heirs, faith means nothing and the promise is worthless, 15 because the law brings wrath. And where there is no law there is no transgression.
16 Therefore, the promise comes by faith, so that it may be by grace and may be guaranteed to all Abraham’s offspring—not only to those who are of the law but also to those who have the faith of Abraham. He is the father of us all. 17 As it is written: “I have made you a father of many nations.” He is our father in the sight of God, in whom he believed—the God who gives life to the dead and calls into being things that were not.
18 Against all hope, Abraham in hope believed and so became the father of many nations, just as it had been said to him, “So shall your offspring be.” 19 Without weakening in his faith, he faced the fact that his body was as good as dead—since he was about a hundred years old—and that Sarah’s womb was also dead. 20 Yet he did not waver through unbelief regarding the promise of God, but was strengthened in his faith and gave glory to God, 21 being fully persuaded that God had power to do what he had promised. 22 This is why “it was credited to him as righteousness.” 23 The words “it was credited to him” were written not for him alone, 24 but also for us, to whom God will credit righteousness—for us who believe in him who raised Jesus our Lord from the dead. 25 He was delivered over to death for our sins and was raised to life for our justification.
Israel-Only says that only the descendants of Abraham are part of the covenant. But John the Apostle shows that those who are believers are NOT BASED on natural descent or ancestory or blood-line.
11 He came to that which was his own, but his own did not receive him. 12 Yet to all who did receive him, to those who believed in his name, he gave the right to become children of God— 13 children born not of natural descent, nor of human decision or a husband’s will, but born of God.
The flesh of Abraham is not the criteria for salvation but the SPIRIT. We receive the Holy Spirit by faith in Christ.
5 Jesus answered, “Very truly I tell you, no one can enter the kingdom of God unless they are born of water and the Spirit. 6 Flesh gives birth to flesh, but the Spirit gives birth to spirit. 7 You should not be surprised at my saying, ‘You must be born again.’ 8 The wind blows wherever it pleases. You hear its sound, but you cannot tell where it comes from or where it is going. So it is with everyone born of the Spirit.”
Paul said that the Gentiles received the Holy Spirit NOT BY LAW (Circumcision) – this destroys the Israel-Only teaching.
You foolish Galatians! Who has bewitched you? Before your very eyes Jesus Christ was clearly portrayed as crucified. 2 I would like to learn just one thing from you: Did you receive the Spirit by the works of the law, or by believing what you heard? 3 Are you so foolish? After beginning by means of the Spirit, are you now trying to finish by means of the flesh? 4 Have you experienced so much in vain—if it really was in vain? 5 So again I ask, does God give you his Spirit and work miracles among you by the works of the law, or by your believing what you heard? 6 So also Abraham “believed God, and it was credited to him as righteousness.”
7 Understand, then, that those who have faith are children of Abraham. 8 Scripture foresaw that God would justify the Gentiles by faith, and announced the gospel in advance to Abraham: “All nations will be blessed through you.” 9 So those who rely on faith are blessed along with Abraham, the man of faith.
23 Before the coming of this faith, we were held in custody under the law, locked up until the faith that was to come would be revealed. 24 So the law was our guardian until Christ came that we might be justified by faith. 25 Now that this faith has come, we are no longer under a guardian.
26 So in Christ Jesus you are all children of God through faith, 27 for all of you who were baptized into Christ have clothed yourselves with Christ. 28 There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus. 29 If you belong to Christ, then you are Abraham’s seed, and heirs according to the promise.
Israel-Only says that Gentiles had to be circumcised in the past, but Paul says that NOW in Christ, neither circumcision and uncircumcision has NO VALUE. The only thing that matters is FAITH in CHRIST.
It is for freedom that Christ has set us free. Stand firm, then, and do not let yourselves be burdened again by a yoke of slavery. 2 Mark my words! I, Paul, tell you that if you let yourselves be circumcised, Christ will be of no value to you at all. 3 Again I declare to every man who lets himself be circumcised that he is obligated to obey the whole law. 4 You who are trying to be justified by the law have been alienated from Christ; you have fallen away from grace. 5 For through the Spirit we eagerly await by faith the righteousness for which we hope. 6 For in Christ Jesus neither circumcision nor uncircumcision has any value. The only thing that counts is faith expressing itself through love.
