Matthew Poole and continuators on 1 Corinthians 3:15

15 If any mans work shall be burnt, he shall suffer loss : but he himself shall be saved: yet so, as by fire .

But if his work do not abide, if he shall appear upon the more clear and bright shining out of the truth of the Gospel, that though he hath held the foundation right, yet he hath built upon it wood, hay, and stubble, mixed fables and idle stories, and corrupt Doctrine with the Doctrine of the Gospel, he shall suffer loss by it, either by afflicting hand of God, or by a loss of his reputation, or some other way.

But yet God will not cast off a Soul for every such errour, if he keeps to the main foundation Jesus Christ. He shall be saved, though it be as by fire, that is, with difficulty, which certainly is a more natural sense of this Text, than those give, who interpret as by fire, of the fire of the Gospel, or the fire of Purgatory, of which the Papists understand it. For. 1. It is, and always hath been a proverbial form of speech to express a thing obtained by difficulty, we say, It is got out of the fire, &c. 2. For the fire of Purgatory, it is a fiction and meer imaginary thing, and of no further significancy, than to make the Popes Chimney smoak. 3. That pretended fire only purgeth Venial sins: this fire tryeth every mans work, the gold as well as the stubble.
