The theme of Romans leading up to chapter 9 is that Paul had written a letter with the Jews in mind, evidenced by the many Jewish themes throughout, including pointed questions aimed directly at the Jew.
From the start, Paul identifies with the Jew by pointing out the depraved state of the Gentiles, and their condemnation under the Law. But then Paul challenges the Jew with a charge of hypocrisy, when they do some of the very same things as the Gentiles. Paul then points out the hopelessness of achieving righteousness through the Law, while simultaneously pointing out that not all was lost, since there were well known historical Jews such as Abraham, Moses and David who did, in fact, achieve a state of righteousness with God, and this is where Paul points out that it was not through the Law after all, but by faith. This becomes the perfect segue into Christ being the ultimate end of faith. Paul extols the riches of Christ and all that God has eternally stored up for those who believe in Him. That’s when we reach Romans 9. The standing question is that if Christ is the Messiah of the Jews, then why don’t the Jews believe in Him? There’s actually a long history there. God reached out to the Jews with many offers of grace, until God finally had enough, which resulted in their hardening, as recorded at Isaiah 6:9-10, in which God states that He will harden Israel so that they could not receive His Son, or at least, they would not receive His Son without first reconciliation with God. God was not going to have people reject Him, while instead embracing a conquering Messiah to deliver Israel from the Romans. So God sent Christ in the same image of the prophets whom the Jews persecuted before Him. Now Paul’s objective at this stage of Romans 9 was to develop the backdrop for the illustration of the Olive Tree described at Romans 11, in terms of the natural and wild branches, in which the natural branches were being cut off, for a time, so that the wild branches could be grafted in. What Paul was doing in Romans 9 was expressing his sincere passion for the Jew, which was also God’s passion, while highlighting the fact that God was now, as a result of Jewish unbelief, turning to the Gentiles in order to graft them in. Jesus warned the Jews with illustrations that this was going to happen. (Matthew 21:33-45) So Paul sets up God’s sovereign right to first choose the Jewish nation (by using examples like with Isaac, the one chosen to receive the inheritance, including his son Jacob), as the basis to suggest that God also has the right to choose the Gentiles, which validates Paul’s ministry of the gospel to the Gentiles. In other words, if God has the sovereign right to choose the Jews, then it stands to reason that He has the same right to graft in the Gentiles. Additionally, He has the same right to harden the Jews, which is what He warned at Jeremiah 18:1-13 and what He did at Isaiah 6:9-10, and ultimately quoted as its fulfillment at John 12:36-43. When Paul asks the question of what right does the pot have in responding back to the Potter, this is a question aimed at the unbelieving Jews (or at least, unbelieving in the Messiah, Christ), in anticipation of their protest against God’s hardening, in terms of the Jews, the natural branches, having been removed from the Olive Tree. But even despite the hardening, Paul points out that it is a “partial hardening” until the times of the Gentiles are fulfilled. So this is what I see going on in the book of Romans, and it has nothing to do with either Calvinism or Arminianism.
Calvinist, Charles Spurgeon, states: “It would also be unnecessary to repeat the whole of the 9th chapter of Romans. As long as that remains in the Bible, no man shall be able to prove Arminianism; so long as that is written there, not the most violent contortions of the passage will ever be able to exterminate the doctrine of election from the Scriptures.” (Election, emphasis mine)
Daniel Whedon explains: “The early Christian fathers, like Paul, encountered the same doctrine of unconditional election of all Jews.” (Commentary on the New Testament, Vol.III: Acts-Romans, p.350, emphasis mine)
Whedon adds: “With this proud expectation of salvation by blood and circumcision--by birth and works--Paul’s Christianity, salvation by faith in Christ, came into deadly issue.” (Commentary on the New Testament, Vol.III: Acts-Romans, p.350, emphasis mine)
Whedon writes: “After expressing profound grief at unbelieving Israel’s downfall (1-5), Paul maintains that from the patriarchs downward it was the spiritual Israel by faith that was accepted, and the false Israel by unfaith that was rejected (6-13) that this accords with Old Testament history (14-18), with the true principles of free-agency and probation (19-24), with ancient prediction (25-29), all presupposing that the law of acceptance by faith and rejection by unfaith underlies the whole history (30-33).” (Commentary on the New Testament, Vol.III: Acts-Romans, pp.350-351, emphasis mine)
In Romans 9, “profound grief” meets “proud expectation.”
One member of The Society of Evangelical Arminians explains: “I see Romans 9 as a lesson that God is sovereign and can do as He pleases and so save whomever He wants to save (it is not dealing primarily with the issue of salvation but of sovereignty, especially in the history of Israel). The chapter begins with a history lesson of how God was sovereign in the history of Israel. Romans 10 is then on the issue of salvation through faith. Romans 11 then puts it all together in relation to both Jews and Gentiles. Calvinists run to Romans 9 to ‘prove’ their view. Romans 9 proves that God is sovereign. But it is an unjustified jump from the fact that God is sovereign and so does as He pleases, to the conclusion that He has preselected who would be saved and damned before they ever existed. If you treat Romans 9-11 as the unit that it is, and as a progressive argument, it argues clearly against the Calvinist view and for the Noncalvinist view.” (SEA)
Arminian, Robert Shank, explains: “...Romans 9 must be understood in light of Romans 9:30-11:36, in which Paul affirms that, instead of acting arbitrarily toward men (as He has a right to do as sovereign Creator), God is governed in His actions by His purpose of grace toward all men (Romans 11:32, Titus 2:11, ect.).” (Elect in the Son, p.174)
Michael Brown explains: “In Romans, the ninth chapter, you know where Paul makes it clear that God hardens who He wants and has mercy on who He wants, he comes to the conclusion of it all, which is that God wants to have mercy on all. So does it just mean Jew and Gentile generically? Isn’t the whole purpose of the passage, the mystery of Israel, and where this fits in with the salvation of the Gentiles?, and tells us at the conclusion that God wants to have mercy on all?” (Why I Am Not a Calvinist)
Yes, the Jews rejected the Gospel, but they are the “chosen people.” How does their rejection of the Gospel justify Paul turning to the Gentiles and preaching the Gospel to them? First, God appointed him to it. Second, God will accept the Gentiles on the same grounds that He accepted their fore-father, Abraham, through faith. Therefore, here it is at Romans 9-11 that Paul deals with the controversy between Jew and Gentile, defending the Gospel, in terms of both God’s sovereign right to save who He will and how He will.
First, Paul didn’t turn to the Gentiles because he stopped loving the Jews. Far from it! Paul stated that he wished that all of the Jews could be saved, and was willing to go to Hell, if that’s what it would take for them to be saved: “In the presence of Christ, I speak with utter truthfulness—I do not lie—and my conscience and the Holy Spirit confirm that what I am saying is true. My heart is filled with bitter sorrow and unending grief for my people, my Jewish brothers and sisters. I would be willing to be forever cursed—cut off from Christ!—if that would save them.” (Romans 9:1-3, NLT)
That’s why I do not feel that Romans 9:19 has anything to do with God decreeing sin, and then trying to claim innocence from it. The thrust of Romans chapters 9-11 is Paul’s message to the Jew in terms of why he is reaching out to the Gentiles, and why the Jewish nation has become alienated from God, and what it would take to be restored.
