Knitting a Conundrum

"Please tell me... what 'purifies' one in purgatory???"

That's up to God I guess. But there are some clues in Scripture:

Heb. 12:29 - God is a consuming fire (of love in heaven, of purgation in purgatory, or of suffering and damnation in hell).

1 Cor. 3:10-15 - works are judged after death and tested by fire. Some works are lost, but the person is still saved. Paul is referring to the state of purgation called purgatory. The venial sins (bad works) that were committed are burned up after death, but the person is still brought to salvation. This state after death cannot be heaven (no one with venial sins is present) or hell (there is no forgiveness and salvation).

1 Cor. 3:15 - Paul says though he will be saved, "but only" through fire. The phrase "but only" in the Greek is "houtos" which means "in the same manner." This means that man is both rewarded and saved by fire.

1 Cor. 3:15 - when Paul teaches that those whose work is burned up will suffer loss, the phrase for "suffer loss" in the Greek is "zemiothesetai." The root word is "zemioo" which also refers to punishment. This means that there is an expiation of temporal punishment after our death, which cannot mean either heaven (no need for it) or hell (expiation no longer exists).

1 Cor. 3:13 - when Paul writes about God revealing the quality of each man's work by fire and purifying him, this purification relates to his sins (not just his good works). Protestants, in attempting to disprove the reality of purgatory, argue that Paul was only writing about rewarding good works, and not punishing sins (because punishing and purifying a man from sins would be admitting that there is a purgatory).

1 Cor. 3:17 - but this verse proves that the purgation after death deals with punishing sin. That is, destroying God's temple is a bad work, which is a mortal sin, which leads to death.

1 Cor. 3:14,15,17 - purgatory thus reveals the state of righteousness (v.14), state of venial sin (v.15) and the state of mortal sin (v.17).

1 Peter 1:6-7 - Peter refers to this purgatorial fire to test the fruits of our faith.

Jude 1:23 - the people who are saved are being snatched out of the fire. People are already saved if in heaven, and there is no possibility of salvation if in hell. These people are being led to heaven from purgatory.

Rev. 3:18-19 - Jesus refers to this fire as what refines into gold those He loves if they repent of their sins.

Dan 12:10 - Daniel refers to this refining by saying many shall purify themselves, make themselves white and be refined.

Wis. 3:5-6 - the dead are disciplined and tested by fire to receive their heavenly reward.

Zech. 13:8-9 - God says 2/3 shall perish, and 1/3 shall be left alive, put into the fire, and refined like silver and tested like gold.
