1 Cor:3:12-13 says (KJV) "Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble; 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."
According to classic Catholic belief Purgatory is a place of burning fire, that does the final refining of the gold, silver and precious stones. Is the passage above not definite proof that such a place exists?
No, this passage is not about purgatory. It is about the judgement of the believer.
There is no way that we can resolve the idea of the atonement that comes to us by faith not works and have purgation (works in purgatory) be true see Ephesians 2:8,9
We know because we see Paul talk many more times about it:
"Why do you pass judgment on your brother or sister? Or you, why do you despise your brother or sister? For we will all stand before the judgment seat of God." (
Romans 14:10).
"For we must all appear before the judgment seat of Christ, that each one may receive the things done in the body, according to what we have done whether good or bad." (
2 Corinthians 5:10).
"Knowing that whatever good we do, we will receive the same again from the Lord, whether we are slaves or free." (
Ephesians 6:8).
Finally,
Paul’s statements are clear. It is the man’s
works that are being judged, not his person or soul. The issue at stake is not his salvation or eternal state (heaven or hell), but his rewards. The fire of Christ’s judgment will
test the nature of his earthly works; this judgment does nothing to the sanctification of his soul.
There are two books in heaven, the Book of Life, and of Works. If anyone's name is found in the Book of Life (Faith in Christ) he is not part of the second judgement. If purgation is true we earn (merit) our salvation which is not supported, Hebrews 9:27 cannot be true and purgation be true. If purgation is true then what John writes in Revelation 20:14
"Then death and Hades were thrown into the lake of fire. The lake of fire is the second death. 15 Anyone whose name was not found written in the book of life was thrown into the lake of fire," can't be true. Unless we created another category of people who are excluded from purgation for some reason. Through purgation, one is saved, rev. 20:15 says the people being judged aren't saved.
