Shared ground
Paul opens a discussion about food connected to idol sacrifices by addressing the posture behind the debate. He acknowledges a claim circulating among the Corinthians: “we all have knowledge.” The text explicitly contrasts two effects: knowledge can inflate a person, while love strengthens others and the community (v.1).
Paul then questions self-confidence in one’s insight. Thinking you know is not the same as knowing in the right way (v.2). The passage does not dismiss knowledge as worthless; it warns that “knowledge” can be carried in a way that damages people.
Finally, Paul shifts the focus from claiming knowledge to loving God, and he adds a relational statement: the one who loves God is “known by him” (v.3). In the flow of the argument, God’s recognition outranks human status gained through being “in the know.”
Where interpretation differs (only where needed)
Is “we all have knowledge” Paul’s own statement or a quotation? Some read it as Paul briefly agreeing with a shared point before qualifying it (“yes, knowledge exists, but…”). Others read it as Paul echoing a slogan from the Corinthians that he immediately corrects.
What does it mean to be “known by God”? Some take it mainly as God’s approval or acceptance of the person. Others hear it as relational recognition—God’s knowing them in a covenant-like, personal way—without the verse explicitly spelling out “approval” language.
Why the disagreement exists
Paul’s wording in v.1 can sound like either agreement or a quoted catchphrase, and the text itself does not mark quotation explicitly. In v.3, “known by God” can be heard as either relational language or evaluative language, and Paul does not unpack it here; he uses it to re-center the discussion away from status based on insight.
What this passage clearly contributes
This short unit sets the controlling tone for the longer topic: the central danger is not merely getting a food question wrong, but letting “knowledge” become a tool for pride. The explicit claim is that love “builds up,” and the implied theological frame is that the most important “standing” is not being seen as knowledgeable, but being in right relationship with God—described here as loving God and being known by him (vv.1–3).
