Purgatory is not for those who have died in the state of serious (i.e. mortal) sin. All such persons go to Hell, as is made clear in{ Gal. 5:19-21, 1 Cor. 6:9, and Eph 5:5-8}. Purgatory is for those of the true faith who have been forgiven for their sins, but have yet to make full satisfaction for the sins they have committed.
		
		
	 
You mean like King Solomon? The Bible says about this king:
First--He was the wisest man that ever lived apart from Christ. 
God blessed him richly. 
However:
1 Kings 11:3 And he had seven hundred wives, princesses, and three hundred concubines: and his wives turned away his heart.
--And yet, there is no sign of King Solomon ever repenting of his polygamy even though it is directly against the perfect will of God, and it turned his heart away from Jehovah toward idolatry. 
Is then, King Solomon in Purgatory, so-called? Is that your belief?
--That is not what the Bible teaches. It is eisigesis. It is reading into scripture things that are not there. Here are your myths that you (the RCC) make up, and then call it doctrine even though it has nothing to do with the Bible. 
	
	
		
		
			Therefore, in {1 Cor. 3:12,} the wood, hay and stubble (which are burned) signify the works of a man who has died in the state of justification and has been forgiven of any mortal sins he might have committed. He is therefore eventually saved, but he hasn’t made satisfaction for sins committed after baptism.
		
		
	 
Can't you simply read the scripture for what it says??
1Co 3:12-15
(12)  Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble;
(13)  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.
(14)  If any man's work abide which he hath built thereupon, he shall receive a reward.
(15)  If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.
--The scene is in heaven. 
No person is ever burned, tortured, punished in any way.
It plainly says: "Every man's work shall be made manifest."
"If a man's work abide..."
"If any man's work shall be burned..."
It does not say anything about the punishment of a person. 
It says nothing about a person's sins. No "sin" is mentioned; only works. 
You are reading into this passage things that are not there. 
There is no such thing as a mortal sin. Sin is sin. But sin is not the focus of this passage; "works" are. 
	
	
		
		
			THE CASE OF DAVID IS AN EXCELLENT EXAMPLE OF A MAN WHO HAS BEEN FORGIVEN OF HIS SIN, BUT HASN’T MADE FULL SATISFACTION FOR IT
		
		
	 
First, it has nothing to do with the passage 1Cor.3:11-15.
Second it is an OT passage, and must be evaluated as such. 
	
	
		
		
			A great example of a man who has been forgiven of his serious sin, but hasn’t made satisfaction for it, is found in the case of David. In {2nd Samuel 11} {2 Kings 11}, we read that King David committed adultery with Bathsheba. David also had her husband killed. These are mortal sins. If David would have died in that state, he would have gone to Hell. {1 Cor. 6:9 }
		
		
	 
Your opinion. That is not what the Bible says. David had his salvation, and sin would not take it away. Note David's Psalm of Repentance:
Psa 51:12  
Restore unto me the joy of thy salvation; and uphold me with thy free spirit. 
--David doesn't ask for his salvation or plead for his salvation. He simply wants to have his fellowship restored. He already had his salvation. He never lost it; only his fellowship.
	
	
		
		
			shows us that no adulterers or murderers will enter Heaven. But David repented of his sin when convicted of it by Nathan in {2 Sam 12.}
		
		
	 
What happens when one repents according to David?
Psa 103:12  As far as the east is from the west, so far hath he removed our transgressions from us. 
--David was completely forgiven of all sins--past, present and future, as far as salvation was concerned. That rules out Purgatory. His sin repentance of his sin of adultery and murder simply restored his fellowship. 
	
	
		
		
			{2 Sam. 12:13} “And David said unto Nathan, I have sinned against the Lord. And Nathan said unto David, the Lord also hath put away thy sin; thou shalt not die.”
The Lord took away David’s sin, and Nathan said that he would not die. This means that he would not eternally die. The guilt of the sin was forgiven because David truly repented and turned from it, but was that the end of it? No, full satisfaction for this mortal sin had not been made. We read in {2 Sam 12:14-15 }that David had to suffer the loss of his child to make satisfaction for his sin – a sin which had already been forgiven.
		
		
	 
You are wrong. David could write:
Psa 103:12  As far as the east is from the west, so far hath he removed our transgressions from us. 
--That sounds like he is forgiven, fully forgiven. 
The loss of his child is a consequence of sin. All sin has consequences.
In today's society murder may carry a life sentence or in some places the death sentence. There is a consequence for sin. 
A pregnant mother drinks and does drugs and then gives birth to a deformed child. That is the consequence to her foolishness. It has nothing to do with Purgatory. The mother will suffer with consequence of her foolish behavior the rest of her life, even if she asks for forgiveness. The harm to the child will be irrevocable. But forgiveness at the time of birth might have been granted if asked for.
	
	
		
		
			{2 Sam 12:14-15 }“… because by this deed thou hast given great occasion to the enemies of the Lord to blaspheme, the child also that is born unto thee shall surely die. And Nathan departed unto his house. And the Lord struck the child that Uriah’s wife bare unto David, and it was very sick.”
This provides undeniable proof that the guilt of a sin of a believer can be forgiven without the entire punishment being taken away. The Council of Trent put it this way:
		
		
	 
It is the consequence of the sin. 
	
	
		
		
			it is absolutely false and contrary to the word of God that the guilt [of a sin] is never forgiven by the Lord without the entire punishment also being remitted. For clear and illustrious examples are found in the Sacred Writings { Gen. 3:16 ; Num. 12:14; Num 20:11; II Kings 12:13  etc.   }
In this citation from the Council of Trent, we see references to numerous places in Scripture where a sin is forgiven without the entire punishment also being remitted. The example from{ Num. 20} should be quoted.
{Num 20:11-12} “And Moses lifted up his hand, and with his rod he smote the rock twice: and the water came out abundantly, and the congregation drank, and their beasts also. And the Lord spoke unto Moses and Aaron, Because ye believed me not, to sanctify me in the eyes of the children of Israel, therefore ye shall not bring this congregation into the land which I have given them.”
When Moses, in obedience to God’s command, struck the rock in order to miraculously bring forth water, there was a certain level of hesitation in the act or in the manner in which he and Aaron presented it to the people. A  commentary explains it: “The fault of Moses and Aaron, on this occasion, was a certain diffidence and weakness of faith; not doubting of God’s power or veracity; but apprehending the unworthiness of that rebellious and incredulous people, and therefore speaking with some ambiguity” (Douay-Rheims Commentary).
As a result, God told Moses and Aaron that they would not be the ones to bring the people into the promised land. This was their punishment, even though they remained in God’s favor. This punishment was fulfilled. It was Joshua and Caleb who led the people into the promised land.
		
		
	 
A friend was drinking, got in a car, and then in an accident. The result--the rest of his life he would be a paraplegic--never again to have the use of his legs. The other result--he found forgiveness with God. God forgave him of all his sins, even the drunkenness and any loss of life involved. God forgave him. But forgiveness did not restore his legs!! Do you think it should? 
I can cite you many such examples. 
There is a consequence to sin. 
If you lie and gossip, the consequences of those sins may be eternal in nature. They can destroy a person's life. The consequence of sin.  
	
	
		
		
			Nothing impure shall enter Heaven-
		
		
	 
True. God looks upon me as pure, holy and righteous. If I were to die today I know I would enter heaven--not because of my merit or anything I have done, but because of God's work, specifically the work of Christ on the cross. 
	
	
		
		
			This kind of satisfaction for the remaining punishment due to forgiven sins is often done on Earth by good works and prayers, by suffering trials and tribulations, and by a more perfect adherence to the true faith. If such satisfaction is not done on Earth, it is and must be done in Purgatory – assuming that the person dies in the state of grace (justification). The satisfaction must be done because the Book of Rev, the Apocalypse, makes it clear that nothing impure shall enter Heaven.
		
		
	 
Your doctrine is a mockery of the sufferings of Christ. It is akin to spitting in his face. You have done worse then the Roman soldiers who mocked him, for you mock him in the things that you post and the way your doctrine boasts that you have helped out in the work of Christ.
What heresy!
What an abomination before God. 
Christ alone paid the price of our sins.
1John 2:2 He made a propitiation for our sins, and not for ours only but also for the sins of the whole world. 
But you say you helped out. 
You say you are helping him out in justification. What heresy! 
It is God that justifies (not man)
The RCC doctrine of Purgatory cannot justify anything. Christ already completed the work.
