"Come to terms with your opponent in good time while you are still on the way to the court with him, or he may hand you over to the judge and the judge to the officer, and you will be thrown into prison. I tell you most solemnly, you will not get out till you have paid the last penny" - Matthew 5:25-26 (The Jerusalem Bible)
That is according to the Bible itself. Here's another verse telling about the Purgatory doctrine...
"For example: when you go to the court with your opponent, try to settle with him on the way, or he may drag you before the judge and the judge hand you over to the bailiff and the bailiff have you thrown into prison. I tell you, you will not get out till you have paid the very last penny.'" - Luke 12:58-59 (The Jerusalem Bible)
Actually, in these verses I quote straight from the Holy Scriptures, the opponent is Satan and God is the judge. The prison is purgatory and you will not get out there until you paid the very last penny (which means you have to pay for your sins and you need to repent there).
