Shared ground
Paul explains the purpose behind his team-based handling of a large relief gift: they are deliberately structuring the process to prevent credible accusations (explicit: “avoid blame,” “this bounty … administered by us”). The concern is not only inner sincerity before God, but also public credibility (explicit: “honorable … in the sight of the Lord” and “in the sight of men”).
The passage assumes that visible integrity matters in ministry connected to money. It also presents shared responsibility and tested character as safeguards: another “brother” travels with the group because he has been “proven” reliable and is notably (explicit).
Where interpretation differs
Two details are genuinely unclear.
First, the identity of “our brother” (v. 22) is not stated. Some think he is a known coworker mentioned elsewhere; others think the text intentionally leaves him unnamed because the point is his proven reliability rather than his identity.
Second, “the great confidence … in you” can be read as the brother’s confidence in the Corinthians, or as Paul/the team’s confidence expressed through him. The sentence can support either direction, but in both readings the result is the same: his eagerness is strengthened by a positive expectation about the Corinthians.
Why the disagreement exists
The passage does not supply names, and the pronouns can be read more than one way without changing the main point. Also, Paul describes a purpose (“avoid blame”) but does not spell out every procedure, leaving room for different reconstructions of how formal the accountability measures were.
What this passage clearly contributes
It adds a concrete picture of how Paul links God-centered integrity with public transparency. The text explicitly connects “before the Lord” and “before people,” showing that moral seriousness is meant to be recognizable, especially in handling significant shared resources (the “bounty”). It also contributes the idea that trustworthy administration is supported by multiple people and by reputations tested over time (explicit: “sent … our brother,” “many times proved earnest”).
