1-6 would only contradict your incorrect notion of what the purgatory is, not to what is is really. For example, purgatory is not a punishment but preparation to entering heaven, just like St. Paul’s passage describes the stubble and such burning off; it is not someting that proceeds through time; the fires of purgatory do not intend to annihilate the believer by burning him, etc.
It is generally a good idea to have a good grasp on the notion that you intend to dispute about.
Better still, leave the grotesque error of Protestantism behind and get to know the authentic Christianity before it is too late.
How so? What specifically about 1-6 contradicts it? I see no context at all to support your claim ... or was that just a veiled remark suggesting that you, being a Catholic, are a mature believer and I, being a non-Catholic, am not?
For example, purgatory is not a punishment but preparation ... It is generally a good idea to have a good grasp on the notion that you intend to dispute about.
You should also get to know your own doctrine ...
1475 In the communion of saints, "a perennial link of charity exists between the faithful who have already reached their heavenly home, those who are expiating their sins in purgatory and those who are still pilgrims on earth. between them there is, too, an abundant exchange of all good things."
Your own cathecism teaches that you are atoning for your own sins in purgatory. You in fact proclaim with your doctrine, "the atonement of Jesus Christ was not sufficient to purify a Catholic from all their sin."
Colossians 2:13-14
13 When you were dead in your transgressions and the uncircumcision of your flesh, He made you alive together with Him, having forgiven us all our transgressions,
14 having canceled out the certificate of debt consisting of decrees against us, which was hostile to us; and He has taken it out of the way, having nailed it to the cross.
The atonement of Jesus Christ on the cross was completely sufficient and effective to clease you from all your sin ... purgatory is a very poor substitute.
Better still, leave the grotesque error of Protestantism behind and get to know the authentic Christianity before it is too late.
I left Protestantism long ago. What you have is not authentic Christianity ...
I pray that the Lord Jesus will remove the blinders from your eyes.
