I’ll grant you that we sometimes can’t know for certain what a person’s final spiritual state is, but we can have some pretty strong clues. You might as well surmise that Judas could have repented unto salvation before he hung himself.
Edith Windsor never repudiated her unholy “marriage” to another woman, even unto her death. That is pretty substantive certainty that she died a damned sinner.
That’s why I say we can-— and sometimes must,-— judge things we can objectively observe: words, as true or false; ideas and ideologies as right or wrong, actions and behaviors as good or evil. And say “Woe to the unrepentant who do not turn from their ways, they are bound for the fures of hell.”
But you can’t say with moral certainty that a particular person is in hell. God has not given us that to know.
Yes, even Judas might have repented unto salvation before his last brain lobe uttrrky failed.
It would be presumptuous to say that he did. But it would be despairing to say he couldn’t have. It short-sells Our Lord’s truly unfathomable power to save.
