I would argue it doesn’t mean eternal 90% of the time. In fact, I’ve actually seen the word “forever” used in English to denote something very similar to “long time” much more often. When you really think of it, “forever” may not be that bad of a translation of aionos. It is just that we should not take a figurative translation literally. I read the ESV Bible when I started out. I did not see ECT in it. I do not need the alternative translation. Because of this. You should ask my evangelical friend. I told him this. Then I accepted ECT. Not because I saw it in the Bible, but because I thought my friend and his church knew better and I was “reading something wrong”.
I recall listening to a song which told a story, and it started out with some lyrics like “Forever we learn, forever we die, forever we live a lie”. The characters got involved in some stuff that changed that, and because of simple time discontinuity it would be really difficult to take a literal meaning of “forever” there. It’s much closer to a meaning of “without seeing an end to it”, “continually”, “very long time”, which is fully compatible with the meaning of the Hebrew olam. Considering the use of olam in Jeremiah, I’m confident in my assumption that the language, especially in parables, is figurative.
Is ECT just? Well, that’s a can of worms. I’m inclined to say no. And the reason I say no is for two reasons.
One, if I cannot label ECT justice as unjust, then I can distinguish nothing (to me the chasm is too large), in which case everything is 100% meaningless, including the Bible, and everything else. That way leads to absolute meaninglessness, while I hold to the view that humanity generally can understand justice to a reasonable degree. In fact, I would say that ECT is closer to justice systems associated with the more broken, cruel, and fallen forms of humanity than the higher ones (i.e., a totalitarian state compared to a democratic state compared to Star Trek). ECT has prospered during some of the worst ages in humanity’s history where all sorts of atrocities have been committed and ECT-style punishments done on Earth. High order humanity, on the other hand, correlates with rehabilitation and crazy ideas like forgiveness. Of course, I see humanity as moving towards more human-centered justice programs, and the further I go there, the less ECT makes sense.
Two, if I were to take the second position and say “ECT is just”, I wouldn’t be able to justify it with anything. It would be a completely blank view, backed by absolutely nothing, making absolutely no sense in light of anything in this world. It’s about as logical as believing that a teapot rotates around Jupiter. ECT lives an dies by “The Bible maybe says so”, and I never found that as a satisfactory argument, because the Bible says different things to different people by the nature of the work, and a detached religion grounded in itself and circular reasoning is a false religion. ECT, being circular and ungrounded, is therefore a false view, as well. Views like ECT typically have to be heavily hammered into the heads of young children because of this.
“If God ordered ECT, would it be just?” is what I call a false hypothetical. Similar hypotheticals are especially popular among atheists “If God did not exist, would X change”. The problems with such is that they attempt to define the latter in terms of the former when there’s no logical progression to do so. In fact, this is a bit similar to “Can God create an object he can’t lift?” or “If God says a blue pen is red, does it become read?” or something. My first complaint is that the hypothetical itself is silly.
In an attempt to answer a question, I will go to the Euthyphro dilemma. Either things are just because God does them, or God does things because they are just. I utterly reject the former. And I believe the hypothetical, in fact, relies on the latter view. The former view has some very dire consequences, those being that there’s no reason to do or not do anything at all, and that sin does not, in fact, really exist. I.e., the things God defines as sin are arbitrary, and only He decided that they’re bad, but they’re not really bad. So a person can go around murdering with a clear conscience because these things are not really bad and there’s actually no morality. This kind of a view drives one to atheism really fast. Also, ECT (especially of the Calvinist variety) actually leads to the same conclusion from the selfish viewpoint. Since what you do does not matter, you’re doomed anyway, everything is allowed. Ugh.
So, no, things do not become magically just because God orders them. Euthyphro’s dilemma is, of course, a complex topic that I do not want to spend all day here but I only favor one horn of it. So, going from there. As such, assuming God is just, God would only order ECT if it was indeed just, so the question is not “if God ordered it, would it be just?” but simply “is ECT just?”. And it stays there.
Now, a different question, which I think is the one that you are really asking, is this. If the Bible said, in the most explicit and undeniable way, that God does ECT, would I buy it? No, I would not. I would much sooner reject Christianity than accept this as justice. I have rejected Islam and other religions on grounds of immorality and injustice. I distinguish religions by what they preach and nothing more. I chose Christianity over Judaism because of what Jesus taught (every serious Christian needs to take a look at Judaism). I have left room, in the past and still do, that if someone gave me a very good explanation of ECT, I would buy it. But only then, and such explanation has not appeared. The Bible is not explicit on ECT. ECT requires a highly literal reading and is not plain in all translations. All explanations of ECT rely on a huge amount of unbiblical assumptions. In other words, sure, there may be a potentiality. There may be a teapot rotating around Jupiter. I honestly have very little reason to believe in either. So I won’t.
The burden of proof is on you, and I haven’t seen any good proof yet. And you need to prove every thing you use in your explanation.
Everyone deserves ECT? Death is ECT? Destruction is ECT? Punishment is according to the status of the victim? Love is conditional and only towards certain people? You can’t just pull this out of thin air, you need some biblical or logical support for it. I’ve seen none. ECT can arise from a few certain verses. But it cannot be explained by any verses. I find that strange, and very suspicious, and if that is not proof of a faulty translation/interpretation/extrapolation, I don’t know what is.
