NIV:
Galatians 2:16
know that a man is not justified by observing the law, but by faith in Jesus Christ. So we, too, have put our faith in Christ Jesus that we may be justified by faith in Christ and not by observing the law, because by observing the law no one will be justified.
KJV:
Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified.
Galatians 2:16 (Douay-Rheims 1899 American Edition)
16But knowing that man is not justified by the works of the law, but by the faith of Jesus Christ; we also believe in Christ Jesus, that we may be justified by the faith of Christ, and not by the works of the law: because by the works of the law no flesh shall be justified.
So what?
Nothing you have stated addresses the issue that Scripture, itself, seems to support the idea that there is a Purgatory.
Nothing you have posted proves anything at all, or disproves anything at all.
Those in Purgatory are NOT in hell, therefore, they have been “saved” (From HELL!) -— They just are not ready for Heaven.
Besides the fact that your citations do not disprove Purgatory, or even address the subject, something else must be noted:
If you wanted to make the point that someone who followed ALL of the Commandments, yet did not believe in God, would not go to Heaven, how would you make that point, and what language would you use?
