Having just finished the whole thing (and so providing a timestamp map in the initial threadpost now ), I think the most astonishing answer was Duane’s final answer to the final question.
After leaning so hard on how immortal life is conditional on God and especially on loyalty to God (per the usual anni approach), Duane is asked why the beast and the prophet and Satan do not die if other sinners are annihilated: why does their torment continue “forever and ever”? (Worth noting that RevJohn says this, in the same mode of translation, about human followers, too. Duane appealed to RevJohn frequently for scriptural evidence in favor of his position, so he himself opened RevJohn for comments; I don’t recall if he skipped around that particular saying about human sinners.)
I had expected him to answer the obvious anni fashion with, “Duh, they’re annihilated, too,” (but if they’re being tormented forever they haven’t been annihilated forever), or “Duh, they aren’t real persons just typological personalizations of systems” (but then how could they be “tormented” in any way), or “Duh, they’re tormented for an indistinctly long period of time which is what the phrase means, eons of the eons, before being annihilated.” Which I’d be willing to buy, other things being equal.
His actual answer amounted to, “Duh, because that’s Satan. He’s super-evil so deserves more punishment.” Which got a smattering round of happy applause.
And Duane’s position wasn’t that Satan and other super-evil persons deserve more punishment before being annihilated. The questioner followed up with something like, “But they don’t ever die”, AND DUANE AGREED WITH THAT! His explanation? Satan is inherently immortal.
