1 Corinthians Chapter 3 · The Foundations of Unity

In Chapter 1, Paul confronted the Corinthians' division by pointing them to the scandal of the cross. In Chapter 2, he explained that true spiritual insight comes only through the Holy Spirit. Now in Chapter 3, he diagnoses the root of their factionalism: spiritual immaturity. They are behaving like ordinary people, driven by jealousy and rivalry, and Paul gives them a blunt assessment — "I had to feed you with milk, not solid food" (v.2). He then shifts to a series of powerful metaphors: planting and watering, building construction, and the temple of God. Through each, Paul dismantles human boasting and re-centers the church on God's work alone. The chapter moves from diagnosis to warning to promise. The Corinthians were measuring their leaders by worldly standards, comparing Paul to Apollos as though the church were a debate society. Paul dismantles this entirely: the planter and the waterer are nothing; it is God who gives the growth (v.7). Then comes the sobering image of the Day of testing, when each person's work will be revealed by fire (v.13). The church is God's temple, and destroying it through division brings God's judgment. Yet for those who stand firm, God has prepared what no eye has seen — riches hidden from the world (v.21, cf. 2:9).
