What's the Word?

[Puzzler]

There’s a word that is something like ‘apostocy’, but it’s longer. It means that Hell is not eternal, but that people go there for a really long time. It’s not a Catholic thought. I think they shot it down during one of the counsels, but I don’t know which one. Some well known Catholics during that time had believed the idea… What I’m looking for is what the word is, who believed in this idea, and during which counsel(s) it was discussed, so that I can do further research.
I’m getting stuck before I get started because I don’t know what the word is.

Any information would be greatly appreciated.

Is it apokatastasis ton panton?

Maybe this will help…

III. ETERNITY OF HELL.—Many admit the existence of hell, but deny the eternity of its punishment. Conditionalists hold only a hypothetical immortality of the soul, and assert that after undergoing a certain amount of punishment, the souls of the wicked will be annihilated. Among the Gnostics the Valentinians held this doctrine, and later on also Arnobius, the Socinians, many Protestants both in the past and in our own times, especially of late (Edw. White, “Life in Christ”, New York, 1877). The Universalists teach that in the end all the damned, at least all human souls, will attain beatitude ( apokatastasis ton panton , restitutio omnium , according to Origen). This was a tenet of the Origenists and the Misericordes of whom St. Augustine speaks (De Civ. Dei, XXI, xviii, n. 1, in P.L., XLI, 732). There were individual adherents of this opinion in every century, e.g. Scotus Eriugena; in particular, many rationalistic Protestants of the last centuries defended this belief, e.g. in England, Farrar, “Eternal Hope” (five sermons preached in Westminster Abbey, London and New York, 1878). Among Catholics, Hirscher and Schell have recently expressed the opinion that those who do not die in the state of grace can still be converted after death if they are not too wicked and impenitent.
