Okay, my ball.
However, instead of using Paul, I'm going to use Jesus' own words, in the Gospel. Then, perhaps, we can view Paul's words in light of Jesus', as opposed to seeing Jesus' words in Paul's light.
Matt. 5:26,18:34; Luke 12:58-59 – Jesus teaches us, “Come to terms with your opponent or you will be handed over to the judge and thrown into prison. You will not get out until you have paid the last penny.” The word “opponent” (antidiko) is likely a reference to the devil (see the same word for devil in 1 Pet. 5:8) who is an accuser against man (c.f. Job 1.6-12; Zech. 3.1; Rev. 12.10), and God is the judge.
Matt. 5:48 - Jesus says, "be perfect, even as your heavenly Father is perfect." We are only made perfect through purification, and in Catholic teaching, this purification, if not completed on earth, is continued in a transitional state we call purgatory.

Matt. 12:32 – Jesus says, “And anyone who says a word against the Son of man will be forgiven; but no one who speaks against the Holy Spirit will be forgiven either in this world or in the next.” Jesus thus clearly provides that there is forgiveness after death. The phrase “in the next” (from the Greek “en to mellonti”) generally refers to the afterlife (see, for example, Mark 10.30; Luke 18.30; 20.34-35; Eph. 1.21 for similar language). Forgiveness is not necessary in heaven, and there is no forgiveness in hell. This proves that there is another state after death
Luke 16:19-31 - in this story, we see that the dead rich man is suffering but still feels compassion for his brothers and wants to warn them of his place of suffering. But there is no suffering in heaven or compassion in hell because compassion is a grace from God and those in hell are deprived from God's graces for all eternity. So where is the rich man? He is in purgatory.
Read carefully:
Matthew12:32: And whosoever speaketh a word against the Son of man, it shall be forgiven him: but
whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come.
Speaking personal blasphemy against Jesus, as the scribes and Pharisees did during His time was forgiveable by Jesus; He even forgave them for crucifying Him. However, the eternal decision of rejecting the call to Salvation that only comes through the revelation of The Holy Spirit during a person's lifetime here on earth
cannot be forgiven. They have willfully decided to reject the Truth and thus seal their fate in the world to come.
People who during their lifetime on earth willingly and with a repentant heart respond to the Holy Spirit's prompting of God's Plan of Salvation through Jesus receive eternal salvation that is sealed by the power of the Holy Spirit. Here is what the Holy Bible states and it is in your Bible as well:
Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.
And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption. Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice: And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you. (Ephesians 4:29-32)
The RCC teaching of "purgatory" is wrong as it gives the false sense of feeling for a person to believe, "Oh, well, if I couldn't make it right in my lifetime, I'll get another chance in the spiritual waiting area until I get it right."
Purgatory is a false teaching and is not what Jesus taught at all. You even cited a portion where once a person is dead they cannot make it back across the Great Spiritual Divide as told in the parable of Lazarus and the rich man who went to hell. Here it is in text:
Luke, Chapter 16:
19: There was a certain rich man, which was clothed in purple and fine linen, and fared sumptuously every day:
20: And there was a certain beggar named Lazarus, which was laid at his gate, full of sores,
21: And desiring to be fed with the crumbs which fell from the rich man's table: moreover the dogs came and licked his sores.
22: And it came to pass, that the beggar died, and was carried by the angels into Abraham's bosom: the rich man also died, and was buried;
23: And in hell he lift up his eyes, being in torments, and seeth Abraham afar off, and Lazarus in his bosom.
24: And he cried and said, Father Abraham, have mercy on me, and send Lazarus, that he may dip the tip of his finger in water, and cool my tongue; for I am tormented in this flame.
25: But Abraham said, Son, remember that thou in thy lifetime receivedst thy good things, and likewise Lazarus evil things: but now he is comforted, and thou art tormented.
26: And beside all this, between us and you there is a great gulf fixed: so that they which would pass from hence to you cannot; neither can they pass to us, that would come from thence.
27: Then he said, I pray thee therefore, father, that thou wouldest send him to my father's house:
28: For I have five brethren; that he may testify unto them, lest they also come into this place of torment.
29: Abraham saith unto him, They have Moses and the prophets; let them hear them.
30: And he said, Nay, father Abraham: but if one went unto them from the dead, they will repent.
31: And he said unto him, If they hear not Moses and the prophets, neither will they be persuaded, though one rose from the dead.
