Planting, Watering, and the Only Foundation

Paul opens by denying that the Corinthians presently display the maturity implied by being pneumatikoi, "spiritual." He calls them sarkinoi or sarkikoi, "fleshly," and infants in Christ, pointing to jealousy and strife as evidence that they are behaving according to ordinary human patterns. The distinction is not between Christians and non-Christians, since Paul still addresses them as "in Christ," but between immature conduct and the Spirit-shaped maturity claimed in 2:6-16.

Verses 5-9 recast factional leaders as servants through whom the Corinthians believed. Paul planted, Apollos watered, but God repeatedly receives the decisive role as the one giving growth. The metaphors then shift: the community is God's field and God's building. Paul, as architektōn, "master builder," laid the foundation, identified explicitly as Jesus Christ. Later builders may use materials of differing quality, and their work will be revealed by the eschatological "Day" and tested by fire. Scholars debate whether the passage concerns ministers specifically or Christian works more generally; the immediate context favors those building up the church.

Verses 16-23 intensify the building image by calling the congregation God's temple, naos, in whom God's Spirit dwells. The plural "you" makes the corporate sense primary. Anyone who destroys God's temple faces divine judgment. Paul then cites Job 5:13 and Psalm 94:11 to reverse conventional claims to wisdom. The conclusion, "all things are yours," relativizes attachment to Paul, Apollos, or Cephas: the leaders belong to the church's benefit, the church belongs to Christ, and Christ belongs to God.

1 Corinthians 3 applies the contrast between divine and human wisdom directly to the Corinthians' factionalism. Paul challenges their claim to spiritual maturity by describing them as "fleshly" and as infants in Christ because jealousy and rivalry still characterize them. He then dismantles attachment to individual teachers through agricultural imagery: Paul planted, Apollos watered, but God gave the growth. Ministers therefore have subordinate and complementary roles within God's work.

The chapter then shifts from field to building imagery. Paul portrays himself as a skilled master builder who laid Jesus Christ as the foundation, while subsequent workers must take care how they build. Their work will be tested by fire, introducing questions about ministerial accountability and eschatological evaluation. Finally, Paul identifies the community itself as God's temple indwelt by the Spirit and returns to the theme of wisdom: worldly wisdom is foolishness before God, and believers should not boast in human leaders because all legitimate ministers belong to them, while they belong to Christ and Christ to God.
