For the Bible text, I started with the NRSVue but made some adaptations because this is genuinely hard to translate well. I added some slashes to give a sense of the range of what Paul is saying. The word usually rendered "natural" or "unspiritual" also carries the connotation of selfish or self-centered. The issue Paul is naming isn't that some people lack a spiritual gene. It's that self-centeredness makes the things of God look like foolishness.
Verse 2:16—"We have the mind of Christ." We have access to the mind of God, the Spirit of God which searches the deep things of God. Whatever the spiritual life is, it should be one that leads to that level of intimacy with God's heart and mind.
Chapter 3:1-4 gets at what "fleshliness" or "unspirituality" actually looks like in practice: jealousy, quarreling, and sectarianism. That's it. That's the diagnosis. Not some exotic spiritual failure. Just "I belong to Paul" and "I belong to Apollos"—the same faction-building from chapter 1. Paul keeps circling back to this because it's the root of everything wrong in Corinth.
And here again we get the theme of "we participate but God is the one doing the thing." Paul planted, Apollos watered, but God gave the growth. The metaphors get a little mixed—we're planting and watering a field that's somehow also a building—but Paul is not exactly known for his tidy imagery.
Verse 9—"we are God's coworkers." The word is synergos, where we get the cringy corporate term "synergy." But it means joint energy, joint work. This is koinonia language again—partnership with God, not hierarchy.
Verses 10-15 are, according to David Bentley Hart, "the fullest picture provided in Paul's writing of the criteria and nature of eschatological judgment." And it's worth paying attention to what it says. Everyone goes through fire. But it's not the people who suffer—it's our work that either burns up or survives. The builder whose work is burned up "will suffer loss; the builder will be saved, but only as through fire."
This is the early church's picture of judgment. The purifying, refining fire of God is for our benefit and for our good. It is not punishment. It is not retribution. It is not eradication. It refines and purifies. Everyone is saved. Some lose what they built. But the fire is not the enemy—it's the thing that burns away everything that isn't gold.
Questions for reflection:
If fleshliness is defined here as jealousy, quarreling, and faction-building, how does that reframe what it means to be "spiritual"?
What would change about your understanding of God's judgment if you took verses 13-15 seriously—that the fire is refining, not retributive, and that the builder is always saved?
