Denzinger 211. Liber Adversus Origen. Can. 9. If anyone says or thinks that the punishment of demons or wicked men is temporary, and that at some point it will end, or that the reintegration of demons or wicked men will happen, let him be anathema.
Denzinger 223. II Constantinople, can. 11. If someone does not anathematize [···] Origen, along with their wicked writings, an all heretics, condemned by the Holy Catholic and Apostolic Church [···] and all who think or thought like the aforementioned heretics, [···] let that one be anathema.
Denzinger 271. Lateran Council. Can. 18. Basically, the same as D223
I guess is one of those things like millennialism, where many of the Early Fathers held it but was latter condemned.
like St. Clement of Alexandria, St. Jerome, St. Gregory of Nyssa, and likely St. Gregory nαzιanzen as well, as the CE explains.
Let's see what my patrology book says...
St. Clement of Alexandria: «Clement defends, like Plato, that divine punisment has no other objective that purifying. Plato wrote: "He who bears a punishment, admits some benefit". However, Clement does not explicitly apply this expression to hell.»
St. Jerome: «Pope Damasus transfered him from Antioch to Constantinople: here he was taught by St Gregory nαzιanzen, and became thrilled by Origen's exegetic method. At this time (381) he had a friendly relationship with St. Gregory of Nyssa»
«Now an adversary of Origen, he translated in 395 the four books
De principiis to fight his now enemy Rufinus» Mentions another 2 books against origenism.
«Like Ambrosius, Jerome teaches that all who deny God (negantes et impii) will suffer the eternal punishment of hell; but not christians, even if they are "peccatores", because the Judgement Day this ones will get a mercifull sentence.»
St. Gregory nαzιanzen: «Kids are innocent, and those who died without baptism wont suffer the punisments of hell, but they also wont enjoy Beatitude»
And for St. Gregory of Nyssa, nothing to add to what you posted.
So St. Jerome, St. Gregory of Nyssa and St. Gregory nαzιanzen all held the opinion of Origen, that was later condemned, and two of them ended up rejecting it at least partially. And St. Clement might as well be talking about purgatory.
