{6} Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble;

(6) Thirdly he shows that they must take heed that the upper part of the building is answerable to the foundation. That is that admonitions, exhortations, and whatever pertains to the edifying of the flock, is answerable to the doctrine of Christ, in the matter as well as in form. This doctrine is compared to gold, silver, and precious stones: of which material Isaiah also and John in the Revelation build the heavenly city. And to these are the opposites, wood, hay, stubble, that is to say, curious and vain questions or decrees: and to be short, all the type of teaching which serves to vain show. For false doctrines, of which he does not speak here, are not correctly said to be built upon this foundation, unless perhaps in show only.

People's New Testament

3:12 If any man buildeth upon this foundation. There is only one foundation for all builders to build upon. The church or temple will be of the character of the material built upon it.

Gold, silver, precious stones. If this material be precious and imperishable, if apostolic doctrines and men molded into the image of Christ be this material, it is well.

Wood, hay, stubble. If erroneous doctrines and unstable men, this will all be revealed in due time.

Wesley's Notes

3:12 If any one build gold, silver, costly stones - Three sorts of materials which will bear the fire; true and solid doctrines. Wood, hay, stubble - Three which will not bear the fire. Such are all doctrines, ceremonies, and forms of human invention; all but the substantial, vital truths of Christianity.

Jamieson-Fausset-Brown Bible Commentary

12. Now-rather, "But." The image is that of a building on a solid foundation, and partly composed of durable and precious, partly of perishable, materials. The "gold, silver, precious stones," which all can withstand fire (Re 21:18, 19), are teachings that will stand the fiery test of judgment; "wood, hay, stubble," are those which cannot stand it; not positive heresy, for that would destroy the foundation, but teaching mixed up with human philosophy and Judaism, curious rather than useful. Besides the teachings, the superstructure represents also the persons cemented to the Church by them, the reality of whose conversion, through the teachers' instrumentality, will be tested at the last day. Where there is the least grain of real gold of faith, it shall never be lost (1Pe 1:7; compare 1Co 4:12). On the other hand, the lightest straw feeds the fire [Bengel] (Mt 5:19).

Matthew Henry's Concise Commentary

3:10-15 The apostle was a wise master-builder; but the grace of God made him such. Spiritual pride is abominable; it is using the greatest favours of God, to feed our own vanity, and make idols of ourselves. But let every man take heed; there may be bad building on a good foundation. Nothing must be laid upon it, but what the foundation will bear, and what is of a piece with it. Let us not dare to join a merely human or a carnal life with a Divine faith, the corruption of sin with the profession of Christianity. Christ is a firm, abiding, and immovable Rock of ages, every way able to bear all the weight that God himself or the sinner can lay upon him; neither is there salvation in any other. Leave out the doctrine of his atonement, and there is no foundation for our hopes. But of those who rest on this foundation, there are two sorts. Some hold nothing but the truth as it is in Jesus, and preach nothing else. Others build on the good foundation what will not abide the test, when the day of trail comes. We may be mistaken in ourselves and others; but there is a day coming that will show our actions in the true light, without covering or disguise. Those who spread true and pure religion in all its branches, and whose work will abide in the great day, shall receive a reward. And how great! how much exceeding their deserts! There are others, whose corrupt opinions and doctrines, or vain inventions and usages in the worship of God, shall be made known, disowned, and rejected, in that day. This is plainly meant of a figurative fire, not of a real one; for what real fire can consume religious rites or doctrines? And it is to try every man's works, those of Paul and Apollos, as well as others. Let us consider the tendency of our undertakings, compare them with God's word, and judge ourselves, that we be not judged of the Lord.

Matthew Henry's Whole Bible Commentary

Verses 11-15

Here the apostle informs us what foundation he had laid at the bottom of all his labours among them-even Jesus Christ, the chief corner-stone, Eph. 2:20. Upon this foundation all the faithful ministers of Christ build. Upon this rock all the Christians found their hopes. Those that build their hopes of heaven on any other foundation build upon the sand. Other foundation can no man lay besides what is laid-even Jesus Christ. Note, The doctrine of our Saviour and his mediation is the principal doctrine of Christianity. It lies at the bottom, and is the foundation, of all the rest. Leave out this, and you lay waste all our comforts, and leave no foundation for our hopes as sinners. It is in Christ only that God is reconciling a sinful world to himself, 2 Co. 5:19. But of those that hold the foundation, and embrace the general doctrine of Christ's being the mediator between God and man, there are two sorts:-

I. Some build upon this foundation gold, silver, and precious stones (v. 12), namely, those who receive and propagate the pure truths of the gospel, who hold nothing but the truth as it is in Jesus, and preach nothing else. This is building well upon a good foundation, making all of apiece, when ministers not only depend upon Christ as the great prophet of the church, and take him for their guide and infallible teacher, but receive and spread the doctrines he taught, in their purity, without any corrupt mixtures, without adding or diminishing.

II. Others build wood, hay, and stubble, on this foundation; that is, though they adhere to the foundation, they depart from the mind of Christ in many particulars, substitute their own fancies and inventions in the room of his doctrines and institutions, and build upon the good foundation what will not abide the test when the day of trial shall come, and the fire must make it manifest, as wood, hay, and stubble, will not bear the trial by fire, but must be consumed in it. There is a time coming when a discovery will be made of what men have built on this foundation: Every man's work shall be made manifest, shall be laid open to view, to his own view and that of others. Some may, in the simplicity of their hearts, build wood and stubble on the good foundation, and know not, all the while, what they have been doing; but in the day of the Lord their own conduct shall appear to them in its proper light. Every man's work shall be made manifest to himself, and made manifest to others, both those that have been misled by him and those that have escaped his errors. Now we may be mistaken in ourselves and others; but there is a day coming that will cure all our mistakes, and show us ourselves, and show us our actions in the true light, without covering or disguise: For the day shall declare it (that is, every man's work), because it shall be revealed by fire; and the fire shall try every man's work, of what sort it is, v. 13. The day shall declare and make it manifest, the last day, the great day of trial; see ch. 4:5. Though some understand it of the time when the Jewish nation was destroyed and their constitution thereby abolished, when the superstructure which judaizing teachers would have raised on the Christian foundation was manifested to be no better than hay and stubble, that would not bear the trial. The expression carries in it a plain allusion to the refiner's art, in which the fire separates and distinguishes the dross from the gold and silver; as it also will silver and gold and precious stones, that will endure the fire, from wood and hay and stubble, that will be consumed in it. Note, There is a day coming that will as nicely distinguish one man from another, and one man's work from another's, as the fire distinguishes gold from dross, or metal that will bear the fire from other materials that will be consumed in it. In that day, 1. Some men's works will abide the trial-will be found standard. It will appear that they not only held the foundation, but that they built regularly and well upon it-that they laid on proper materials, and in due form and order. The foundation and the superstructure were all of a piece. The foundation-truths, and those that had a manifest connection with them, were taught together. It may not be so easy to discern this connection now, nor know what works will abide the trial then; but that day will make a full discovery. And such a builder shall not, cannot fail of a reward. He will have praise and honour in that day, and eternal recompence after it. Note, Fidelity in the ministers of Christ will meet with a full and ample reward in a future life. Those who spread true and pure religion in all the branches of it, and whose work will abide in the great day, shall receive a reward. And, Lord, how great! how much exceeding their deserts! 2. There are others whose works shall be burnt (v. 15), whose corrupt opinions and doctrines, or vain inventions and usages in the worship of God, shall be discovered, disowned, and rejected, in that day-shall be first manifested to be corrupt, and then disapproved of God and rejected. Note, The great day will pluck off all disguises, and make things appear as they are: He whose work shall be burnt will suffer loss. If he have built upon the right foundation wood and hay and stubble, he will suffer loss. His weakness and corruption will be the lessening of his glory, though he may in the general have been an honest and an upright Christian. This part of his work will be lost, turning no way to his advantage, though he himself may be saved. Observe, Those who hold the foundation of Christianity, though they build hay, wood, and stubble, upon it, may be saved. This may help to enlarge our charity. We should not reprobate men for their weakness: for nothing will damn men but wickedness. He shall be saved, yet so as by fire, saved out of the fire. He himself shall be snatched out of that flame which will consume his work. This intimates that it will be difficult for those that corrupt and deprave Christianity to be saved. God will have no mercy on their works, though he may pluck them as brands out of the burning. On this passage of scripture the papists found their doctrine of purgatory, which is certainly hay and stubble: a doctrine never originally fetched from scripture, but invented in barbarous ages, to feed the avarice and ambition of the clergy, at the cost of those who would rather part with their money than their lusts, for the salvation of their souls. It can have no countenance from this text, (1.) Because this is plainly meant of a figurative fire, not of a real one: for what real fire can consume religious rites or doctrines? (2.) Because this fire is to try men's works, of what sort they are; but purgatory-fire is not for trial, not to bring men's actions to the test, but to punish for them. They are supposed to be venial sins, not satisfied for in this life, for which satisfaction must be made by suffering the fire of purgatory. (3.) Because this fire is to try every man's works, those of Paul and Apollos, as well as those of others. Now, no papists will have the front to say apostles must have passed through purgatory fires.
