Does 1 Corinthians 8:4–6 deny or affirm the existence of other gods?

Ffom my observation, Christians have three responses when they learn about the divine council in scripture (and there is no reliable way to predict how it will go ahead of time):

1. Complete apathy: No matter how you draw out the implications of rulership in the spiritual places for the arc of redemptive history, they just shrug and say, “Oh ar.” ❋ For an explication of these implications, see my sermon “What makes a church a church? Part 6: Christians as divine council members”. https://redwoodchurch.substack.com/p/what-makes-a-church-a-church-part-2c0.
2. Complete enthusiasm: You barely need to explain the broadest strokes of what is happening in Deuteronomy 32 or Psalm 82 or Colossians 2—why all the 2s I ask—and they are wondering how no one told them this before and why they failed to spot it all these years.
3. Complete loathing: Every exegetical fallacy and every logical contortion will be meticulously explored as a refuge from this novel, false, distracting, false, divisive, false, foolish, false, ear-tickling, false, liberal, and false doctrine.

I don’t pretend to understand the first response, and I really don’t understand the third—especially since it isn’t indexed to any particular theological position or aptitude. Nonetheless, among more biblically literate evangelical opponents, who tend to favor the ESV, 1 Corinthians 8:4–6 looks like a promising safe haven. This is as ironic as it is unfortunate, because the appeal demonstrates how strongly our use of language influences our theology—and how strongly our theology influences our use of language, and thus our doctrine of scripture and our philosophy of translation:

Therefore, as to the eating of food offered to idols, we know that “an idol has no real existence,” and that “there is no God but one.” For although there may be so-called gods in heaven or on earth—as indeed there are many “gods” and many “lords”—yet for us there is one God, the Father, from whom are all things and for whom we exist, and one Lord, Jesus Christ, through whom are all things and through whom we exist. 1 Corinthians 4:8–6, ESV

The unfortunate irony here is that the Greek explicitly says that there are many gods and many lords. The ESV takes the liberty of trying to “safely explain” the text, rather than representing it.

Young does a good job here, but cf. NHEB, KJV, WEB, ASV, ISV and others:

…for even if there are those called gods, whether in heaven, whether upon earth—as there are gods many and lords many—yet to us is one God, the Father, of whom are the all things, and we to Him; and one Lord, Jesus Christ, through whom are the all things, and we through Him… 1 Corinthians 8:5–6, YLT

By the same token, verse 4 does not say an idol has “no existence” as the ESV would have it; it says an idol is “nothing in the world.” Whether or not Paul is quoting the Corinthians here (he certainly may be), it cannot be that an idol has no existence, since that is a contradiction in terms; but neither can it be that the deity it represents has no existence, since otherwise Paul contradicts himself in chapter 10:

What do I imply then? That food offered to idols is anything, or that an idol is anything? 20 No, I imply that what pagans sacrifice they offer to demons and not to God. I do not want you to be participants with demons. 1 Corinthians 10:19–20, ESV

Paul here echoes his language from chapter 8, affirming that idols are indeed nothing—not because the powers they represent are nonexistent, but rather presumably because:

1. Idols don’t work

Simply put, they are not inhabited by deities as their users suppose. The kind of sympathetic magic that supposedly makes idolatry work is actually false; cf. Jeremiah 10—noting in passing that verse 11 of that passage seems to presuppose the existence of other gods:

Thus shall you say to them: “The gods who did not make the heavens and the earth shall perish from the earth and from under the heavens.” Jeremiah 10:11, ESV

2. The beings behind them are as nothing compared to God

Clearly spiritual beings do stand behind idols, as Paul straightforwardly says—but these beings might as well be nothing when compared with the power of Jesus. The comparison is clearly in terms of importance, as shown by the fact that Paul refers also to the food as nothing. It exists—but it doesn’t matter. Again, putting the text beside Jeremiah 10 is a good starting point for drawing out this theology, but Paul is actually going back more directly to Deuteronomy 32:17, 22:

They sacrificed to demons that were not God [eloah, singular],
      to gods [elohim, plural] they had never known,
to new gods that had come recently,
      whom your fathers had never dreaded…
21 They have made me jealous with what is no god;
      they have provoked me to anger with their idols… Deuteronomy 32:17, 21, ESV

Here Moses explicitly links what we translate as demons, which certainly exist, with elohim—he says these beings are in fact elohim, gods, and that the Israelites sacrificed to them, instead of to God (distinguished with the singular eloah). This was a violation of both the Shema (Deuteronomy 6:4) and the first commandment (Exodus 20:3). Indeed, these are precisely what Paul himself is drawing on in 1 Corinthians 8:6: “to us there is one God,” just as to Israel—but this by no means denies the existence of other gods. The stricture not only makes more sense if they do exist, but is almost incoherent if they do not; far from denying their existence, both Paul and Moses presuppose it. What they are denying, like the rest of scripture’s authors, is the propriety of worshiping these gods—hence the ambivalent language: “they are gods but they aren’t.”

If Moses and Paul didn’t think there were rulers in the heavenly places, gods over the nations, then they wouldn’t say such things in places like Exodus 12:12; 1 Corinthians 2:8; 2 Corinthians 4:4; Ephesians 3:10; 6:12. And that is the real problem with appeals from divine council opponents. They pit scripture against itself.
