In the New Testament, the Greek word often translated “forever”—aiōn or its related forms—does not always mean “everlasting” in the strict, timeless sense. Its meaning flexes with context. For example, in Galatians 4 Paul uses the term when discussing the law about sons and slaves, where the contrast depends on status, not endless duration. In that setting, the word carries the sense of “permanent” or “belonging to the rightful order of things”—the son has a lasting, secure place in the household in a way the slave does not. The point is that aiōn‑language can describe something enduring, fitting, or firmly established without necessarily implying infinite time; the context determines whether the emphasis is on duration, status, or permanence.https://christianchat.com/goto/post?id=5750191
I made a mistake in that boldened conclusion.
It should say -
εἰς τοὺς αἰῶνας only functions idiomatically to mean “forever”, if one arbitrarily chooses to understand it as forever. That would be like saying that sometimes mammals are cats, therefore idiomatically “putting a hypodermic needle into a cat” functions idiomatically to mean “injecting a mammal", as if every time someone reports on a vet injecting a mammal, they may say idiomatically, “The vet injected a cat."
“He injected a cat” and “He injected a mammal” are both true, if the mammal was a cat. He injected a cat would not be true, if the injected mammal was a horse of dog. "Into the ages" and :everlasting” are both true od a time period only if that period is everlastingly int the ages. If it is into seven of an infinite number of ages, it would not be everlasting.
However, we were actually discussing Matt. 25:46, which uses aiOnion, an adjective, age long. "eis ton aiOnas” is “into the ages”, a different phrase not used in Matt. 25:46.
If aiOnion (aeonous/age-long) means having no presently determinable end, then an endless period can be aiOnion (aeonous/age-long). But it can also refer to periods of time that have ends and are not everlasting. So, since it can refer to periods that are limited in duration, one needs to be able to justify interpreting aiOnion as everlasting in any particular context. I have justified it not meaning everlasting in Matt. 25:46, so it is not at all certain that it must mean everlasting in Matt 25:46.
In Matthew 25, the word translated “eternal” derives its meaning from the context of final judgment, where Jesus describes the ultimate, irreversible destinies of human beings. The parallel is deliberate: the righteous enter eternal life, and the wicked enter eternal punishment. But “eternal punishment” does not require the idea of eternal conscious torment; the grammar points to the lasting result, not the ongoing experience. Just as “eternal life” describes a life whose quality and duration are unending, “eternal punishment” describes a judgment whose effect is unending—a punishment from which there is no restoration, reversal, or return. In this context, aiōnios marks the finality of the verdict: the righteous enjoy a life that never ends, and the wicked suffer a loss that can never be undone. The word signals the permanent status of each destiny, not symmetrical experiences of endless duration.
