Sure. Sorry I took so long to reply. I got caught up with something else.
Could we start with the doctrine of purgatory? (1030-1032 CCC) This doctrine conflicts with scripture because it denies the sufficiency of Christ’s sacrificial death:
I don’t agree. I think it is because of the sufficiency of Christ’s sacrificial death that we can be purified of sin in Purgatory.
The blood of Jesus Christ also cleanses of sin in Purgatory.
“If we say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. If we say that we have not sinned, we make Him a liar, and His word is not in us.” 1 John 1:7-10
The blood of Jesus Christ can cleanse of all unrighteousness, even in Purgatory.
“We have been made holy through the sacrifice of the body of Jesus Christ once for all. Day after day every priest stands and performs his religious duties; again and again he offers the same sacrifices, which can never take away sins. But when this priest [Jesus] had offered for all time one sacrifice for sins, he sat down at the right hand of God…because by one sacrifice he has made perfect forever those who are being made holy.” (Hebrews 10:10-14).
I know that you understand the term, “once for all” to mean, “all at once”. But, obviously, the term can’t mean that, because if it did, then the only ones that were made holy would be the ones that lived at the time of the Crucifixion.
We understand the term, “once for all” to mean, “once for all time and for everyone”. We also understand that we are being “made holy”. Thus, it was not a done deal at the time of the Crucifixion. Jesus accomplished all He had set out to do. But we still had to do our part and live our lives. And, if we died imperfectly, with sin still on our souls, then God would have to cleanse our souls before we could be admitted into heaven.
Notice that in Purgatory, we don’t cleanse ourselves. God cleanses us.
For those who repent and believe (trust) in the gospel of Jesus Christ, the blood of Jesus Christ cleanses us from all sin.
True. Either here or in the world to come.
We will not suffer for our sins in purgatory - Jesus Christ paid our sin debt in full.
Some will. Those who die in an imperfect state of grace will have to pay for their sins.
