Paul deals with a potential objection from his dialogue partner, a Jewish person who has tried to keep the Law but now discovers he is just as guilty as the Gentile. If the Jews have spectacularly failed to keep the Law and are enslaved to the “power of sin” in the same way the Gentiles are, what advantage is there to being a Jew?
If it is the case that God chose Israel as his people and gave to them the Law, then their failure may appear to make God’s plan in the Old Testament out to be a failure. This is a problem some readers will have when they read the Old Testament, Israel spectacularly fails in their calling to be the light to the Gentiles; they cannot even “save themselves.”
For Paul, being Jewish is still of great advantage, Paul will return to this in Romans 9:4-5 in much more detail, here he only gives a short answer.
Paul says first, the Jewish people were entrusted with the “oracles of God” (τὰ λόγια τοῦ θεοῦ). The word translated “first” (πρῶτος) can mean first in a sequence. The ESV translates this as “to begin with…” implying the first of a series. There is no “second” item in the list, so commentators think Paul started the list, dropped it until chapter 9. But the word can also mean “of first importance.” In this view, the oracles of God are the most important advantage the Jewish people were given.
The oracles are sayings, but Acts 7:38 uses the same word for the law that was given to Moses (living oracles, λόγια ζῶντα). In Hebrews 5:12 the writer chides his readers for not having understood the “the basic principles of the oracles of God” yet. The phrase is used in 1 Peter 4:11 for words given through the Holy Spirit. In each example the logia of God are the “very words of God” given in the Law and Prophets (Kruse, Romans, 160).
Does Jewish unfaithfulness nullify God’s faithfulness? If the Jews were given the “very words of God” and failed to respond properly to them, perhaps God is not obligated to be faithful toward them.
By way of analogy, if someone acts rude and offensively toward you, sometimes it is socially acceptable to be rude back to them. Since they have broken politeness, you are no longer obligated to be polite. (Someone might react to a spouse who cheats by cheating themselves, since one covenant partner has been unfaithful, the other is released from their own commitment to faithfulness). (If you get pranked, the proper response to prank back?)
Paul’s response to this question is no, God is not released from his covenant with Israel because Israel was unfaithful. To use an analogy from Hosea and the marriage metaphor, Israel was an unfaithful partner who behaved abominably toward God’s loving kindness. Yet God has not divorced his unfaithful spouse, but is in the process of wooing them back to the relationship they had at the beginning in the wilderness.
Even though Israel was an unfaithful covenant partner, God is the ideal example of a faithful covenant partner and will fulfill his side of the covenant regardless of the rebellion of his partner.
In this verse he says only some Jews were unfaithful. Although Romans 9-11 indicates that Israel as a whole failed, there was always a righteous remnant that was faithful to the covenant. Yet even the righteous remnant failed to wholly keep the Law! Therefore Paul can conclude there is no one who can please God (Law-Keeping Jews or righteous Gentiles).
