I’m not contradicting purgatory.
Purgatory, as correctly understood; isn’t punishment. It’s a place to purge the soul, that died without mortal sin but not holy enough to go directly to heaven; of all attachment to sin. Once purged; the soul arises from purgatory and into heaven.
Your misunderstanding of purgatory is distracting you from the basic issue: Hell exists and it’s possible for a believing Christian to go to hell. For people choose to go to hell through their actions and choices. For we must continually work on our salvation: Cultivating our spiritual life and growing in holiness, in tandem with good deeds i.e. works; is that working out your salvation. Sloth in this inevitably leaves one vulnerable to the devil’s operations and will lead one into hell.
As for verses on slothfulness. Unfortunately, I don’t know the verses offhand; though you have confirmed for me in your question that verses elsewhere describe it. Thank you.
But, a straightforward reading of “ Working out your salvation… “ leads to the realization that it’s possible to lose your salvation.
See: It implies in its meaning that we:
- Must work on our salvation and it’s a continual work in progress. It’s in doubt until our death. Conversely, it implies the possibility of slothfulness in not working on it.
- With fear and trembling also indicates that the issue is doubt. Otherwise, it’s pointless to fear and tremble. Thus: It directly refuted the position that we can never lose our salvation.
Saint Paul never taught that you can’t lose your salvation. The verses themselves make it quite clear when read straightforward and literal.
The counterpoint requires some exegetical gymnastics.
