If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire. If any man's work shall be burned, he shall suffer loss - If he have preached the necessity of incorporating the law with the Gospel, or proclaimed as a doctrine of God any thing which did not proceed from heaven, he shall suffer loss - all his time and labor will be found to be uselessly employed and spent. Some refer the loss to the work, not to the man; and understand the passage thus: If any man's work be burned, It shall suffer loss - much shall be taken away from it; nothing shall he left but the measure of truth and uprightness which it may have contained.
But he himself shall be saved - If he have sincerely and conscientiously believed what he preached, and yet preached what was wrong, not through malice or opposition to the Gospel, but through mere ignorance, he shall be saved; God in his mercy will pass by his errors; and he shall not suffer punishment because he was mistaken. Yet, as in most erroneous teachings there is generally a portion of wilful and obstinate ignorance, the salvation of such erroneous teachers is very rare; and is expressed here, yet so as by fire, i.e. with great difficulty; a mere escape; a hair's breadth deliverance; he shall be like a brand plucked out of the fire.
The apostle obviously refers to the case of a man, who, having builded a house, and begun to dwell in it, the house happens to be set on fire, and he has warning of it just in time to escape with his life, losing at the same time his house, his goods, his labor, and almost his own life. So he who, while he holds the doctrine of Christ crucified as the only foundation on which a soul can rest its hopes of salvation, builds at the same time, on that foundation, Antinomianism, or any other erroneous or destructive doctrine, he shall lose all his labor, and his own soul scarcely escape everlasting perdition; nor even this unless sheer ignorance and inveterate prejudice, connected with much sincerity, be found in his case.
The popish writers have applied what is here spoken to the fire of purgatory; and they might with equal propriety have applied it to the discovery of the longitude, the perpetual motion, or the philosopher's stone; because it speaks just as much of the former as it does of any of the latter. The fire mentioned here is to try the man's work, not to purify his soul; but the dream of purgatory refers to the purging in another state what left this impure; not the work of the man, but the man himself; but here the fire is said to try the work: ergo, purgatory is not meant even if such a place as purgatory could be proved to exist; which remains yet to be demonstrated.
