11 For other foundation can no man lay than that is laid, which is Jesus Christ. 12 Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble; 13 Every man’s work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man’s work of what sort it is. 14 If any man’s work abide which he hath built thereupon, he shall receive a reward. 15 If any man’s work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire. (1 Corinthians 3:11-15 KJV)
Our works and rewards
The apostle explains that the foundation of all his labor among the Corinthians was Jesus Christ, the chief cornerstone (Ephesians 2:20). All faithful ministers build upon this foundation, and every Christian must place their hope on it. Anyone who builds their hope of heaven on another foundation builds on sand. “No one can lay any foundation other than the one already laid, which is Jesus Christ” (1 Corinthians 3:11). The doctrine of Christ and His role as mediator is central to Christianity. Without it, we have no comfort or hope as sinners, for it is in Christ that God reconciles the world to Himself (2 Corinthians 5:19).
Among those who hold to this foundation, there are two kinds of builders. Some build with gold, silver, and precious stones (1 Corinthians 3:12)—that is, they teach the pure truths of the gospel, just as Christ revealed them, without alteration. They preach only what Christ taught, keeping His doctrines uncorrupted.
Others build with wood, hay, and stubble. Though they acknowledge Christ as the foundation, they introduce human ideas, opinions, or practices that don’t align with Christ’s teachings. What they build cannot withstand testing. A time will come when everyone’s work will be revealed and tested by fire (1 Corinthians 3:13). This “day” refers to the final day of judgment when the true nature of each person’s work will be exposed. The metaphor alludes to a refining fire that distinguishes between what is valuable and what is worthless. Just as fire separates gold from dross, the judgment will reveal which teachings and works are genuine.
Some works will endure the test and be shown to be faithful and sound. These builders will be rewarded, having not only held to the right foundation but also built upon it carefully and truthfully. Their faithful teaching and labor in Christ’s service will receive eternal reward, far beyond what they deserve. Ministers who preserve and spread pure doctrine will be honored by God.
Others will see their work burned up (1 Corinthians 3:15). Their false doctrines, misguided practices, or human traditions will be exposed and rejected. Though their work is lost, they themselves may still be saved—“but only as one escaping through the flames.” This shows that those who build poorly on the true foundation may still be sincere Christians. Their salvation is possible, though their flawed teaching will bring loss and diminish their reward.
This should teach us to be charitable. Weakness or error in doctrine doesn’t necessarily mean someone is lost. It is unrepentant wickedness that condemns, not mere imperfection. God may reject their work but still save the person, pulling them from the fire while letting their false work burn.
Some have used this passage to support the Catholic doctrine of purgatory, but it does not. First, the fire here is clearly symbolic, not literal—it refers to testing doctrine, not to punishing sin with flames. Second, the fire tests the quality of one’s work; purgatory, by contrast, is said to punish sins not fully paid for in this life. Third, this fire tests every man’s work, including apostles like Paul and Apollos (1 Corinthians 3:13), yet no one claims that apostles pass through purgatory. This interpretation is a human invention, not found in Scripture, and was used in later centuries to support clerical abuse rather than biblical truth.
