1 Corinthians 10:15 Commentary: Paul's Appeal to Wise Men

First Corinthians was written to a congregation proud of its rhetorical skill and spiritual knowledge. Paul had spent chapters 1, 2 demolishing confidence in 'the wisdom of the wise' and 'the disputer of this world.' Now, in chapter 10, he changes tone. The immediate context is a warning against participating in pagan sacrificial feasts, practices that were woven into Corinthian social and religious life. The city was known for its many temples, and meat from sacrifices was often sold in the market or served at civic banquets. Paul's argument picks up from the earlier example of Israel in the wilderness (vv. 1, 13) and then turns to the positive pattern of the Lord's Supper (vv. 16, 17) and the Jewish altar (v. 18).

When Paul says 'I speak as to wise men,' he uses the Greek word phronimois, which denotes not abstract intellectualism but practical prudence, being mindful of one's own interests (Thayer). The term was at home in ethical discussions. The Corinthians prided themselves on this kind of phronēsis (wisdom in action). By calling them to 'judge' (krinate), Paul appeals to their capacity to separate and decide, a verb that can mean 'examine' or 'discern' (Acts 17:11). Paul does not lay down his authority; he invites their participation. This method respects their maturity while exposing a gap between their claim to wisdom and their actual conduct. The setting is a church where factions boasted of different teachers (1 Cor 1:12) and where some thought their 'knowledge' gave them freedom to eat in idol temples (1 Cor 8:1, 13). Paul's appeal here is a pastoral strategy: he asks them to let the truth of the Eucharist, their shared participation in Christ, judge their actions at pagan feasts.

The consulted sources note no significant textual variants for 1 Corinthians 10:15. The verse is consistently attested across manuscripts, with only minor differences in word order (e.g., ‘I speak as to wise men’ vs. ‘As to wise men I speak’) that do not affect meaning.

Early church writers (e.g., Chrysostom, Augustine) cited this verse to affirm that Paul respected the reason of believers. The Reformation period emphasized the phrase ‘judge what I say’ as a warrant for private judgment in matters of doctrine, with JFB explicitly connecting it to the Bereans’ testing of Paul (Acts 17:11). In modern evangelicalism, the verse is often used to encourage believers to study Scripture for themselves rather than rely solely on authorities. The Catholic tradition has read it within the context of Paul’s full teaching on the Eucharist, stressing the duty to examine one’s own conscience and practice. Across traditions, the verse is valued for showing that apostolic authority does not suppress the mind but engages it.

Three-point outline

1. Paul acknowledges their capacity to understand. He calls them 'wise' not to flatter but to engage their God‑given reason. This is not the wisdom of the world he rejected in chapter 1; it is the discernment of those who have the Spirit (1 Cor 2:12, 13).
2. Paul invites them to use that capacity. 'Judge what I say.' The aorist imperative krinate demands a verdict. Paul is confident that when they examine the facts of the Lord's Supper, the Jewish altar, and pagan worship, they will see the incompatibility.
3. The stakes: fellowship with Christ or with demons. Paul's reasoning (vv. 16, 22) shows that every act of worship is a communion. The choice is not about food but about which table you share. The Corinthians' ‘wisdom’ must lead to a decision.

Five-point outline

1. Introduction: Paul reframes the issue at hand (idol feasts) by appealing to the Corinthians' own prized wisdom.
2. Consistency check: Does this contradict 1 Corinthians 1? No, Paul rebukes arrogant human reasoning, but here he invites Spirit‑guided discernment. The difference is the object of trust: the world's logic vs. the logic of the cross (1 Cor 2:16).
3. The central argument: The cup of blessing and the bread of the Lord create communion with Christ (v. 16). Participation in an altar makes you a koinōnos (partner) with that altar (v. 18).
4. Application to idol feasts: What Gentiles sacrifice, they sacrifice to demons (v. 20). You cannot share the Lord's table and the table of demons (v. 21).
5. Conclusion: ‘Judge what I say’ is a call to decision. The Corinthians' wisdom is no excuse for compromise; it is the tool to see the danger.

Illustration hooks

• Business lunch: A Christian executive is pressured to attend a company event where the 'toast' honors a local deity. Do participation and presence communicate approval? Paul's logic asks the same about Corinthian banquets.
• Social media likes: You can 'like' a post that promotes something you oppose. The act itself may be small, but Paul insists that every shared act creates a connection. The Eucharist defines your primary table.
• Sunday morning vs. Saturday night: A life divided between worship and worldly patterns is unsustainable. Paul forces the question: with whom do you really share fellowship?

Questions your congregation is asking

• How do I know when I am using 'wisdom' as an excuse to compromise?
• Is it okay to attend events where beliefs I reject are celebrated, if I don't participate?
• What does the Lord's Supper have to do with the rest of my week?

This verse is a hinge in Paul's argument. He moves from warning (vv. 1, 13) to the positive basis for rejecting idol feasts: the Lord's Supper creates a real communion with Christ. Paul trusts the Corinthians to follow his reasoning. This small group guide will help your group practice the same kind of discernment.

Discussion questions

1. Read 1 Corinthians 10:15. Why does Paul call the Corinthians 'wise men' when he earlier criticized their wisdom (1 Cor 1:19, 20)?
2. Look at the Greek word phronimois (sensible, prudent). How does this differ from the 'wisdom of the world' Paul condemns?
3. What does Paul ask them to 'judge' (v. 15)? Read verses 16, 22 to see the argument he puts before them.
4. How does Paul use the Lord's Supper in verse 16 to make his case? What does 'communion' (koinōnia) mean in this context?
5. In verse 18, Paul compares eating sacrifices with 'participation in the altar.' What does that reveal about how worship works, even in false religion?
6. Based on verses 20, 22, what is the danger of eating in an idol's temple? How does that apply to modern choices about entertainment, work, or relationships?
7. Paul says 'judge what I say.' How can we practice that kind of judging without becoming proud or dismissive of Scripture?
