Matthew 5:25-26
>Settle matters quickly with your adversary who is taking you to court. Do it while you are still together on the way, or your adversary may hand you over to the judge, and the judge may hand you over to the officer, and you may be thrown into prison. 26 Truly I tell you, you will not get out until you have paid the last penny.
Of course, infernalist will claim that here Christ has suddenly deviated from the Sermon on the Mounts' spiritual message in order to offer advice about temporal legal affairs, not to say anything about spiritual punishment.
Catholics get it more right, as they often use this to point to Purgatory, but Purgatory is basically grounded by using all the same Scripture that universalists use to show punishment is not unending, but then breaking it off weirdly into some third category never mentioned anywhere and not recognized by the early Church.
Of course, outside of just "eternal Hell" and "Hell followed by universal reconciliation" there is also the idea that the damned cease to exist: annhilationism.
Universalists have a great many passages to point to that seem unambiguous:
Revelation 21:5
>And he who was seated on the throne said, “Behold, I am making all things new.” Also he said, “Write this down, for these words are trustworthy and true.”All things will be remade in God's final triumph... except some people are excluded under "all."
1 John 2:2
>He is the propitiation for our sins, and not for ours only but also for the sins of the whole world.This means the opposite of what it straightforwardly says.
I Peter 4:6
>For this is why the gospel was preached even to those who are dead, that though judged in the flesh the way people are, they might live in the spirit the way God does.Holy Scripture has a grammatical mistake that heavily implied that the Gospel is preached to those already dead for repentance but really it means "those who heard the Gospel who were alive but have now died." St. Peter just didn't say that because he wanted to save ink.
Hebrews 2:9
>But we see him who for a little while was made lower than the angels, namely Jesus, crowned with glory and honor because of the suffering of death, so that by the grace of God he might taste death for everyone.παντὸς always means all/every, but it definetly means "some" here.
Etc. There are about 4 potential eternal torment lines. There are like 50 universalist lines that seem just as unambiguous.
Notably, in the East, where people spoke the language of the OT fluently, infernalism never took hold the same way and several Church Fathers rejected it. It was in the West, using translations, that infernalism develops.
And the OT
Psalm 30:5
>For his anger is but for a moment, and his favor is for a lifetime. Weeping may tarry for the night, but joy comes with the morning.Psalm 65:2
>O you who hear prayer, to you shall all flesh come.Isaiah 19:21-22
>And the Lord will make himself known to the Egyptians, and the Egyptians will know the Lord in that day and worship with sacrifice and offering, and they will make vows to the Lord and perform them. And the Lord will strike Egypt, striking and healing, and they will return to the Lord, and he will listen to their pleas for mercy and heal them.Isaiah 25:6-8
>On this mountain the Lord of hosts will make for all peoples a feast of rich food, a feast of well-aged wine, of rich food full of marrow, of aged wine well refined. And he will swallow up on this mountain the covering that is cast over all peoples, the veil that is spread over all nations. He will swallow up death forever; and the Lord God will wipe away tears from all faces, and the reproach of his people he will take away from all the earth, for the Lord has spoken.Isaiah 45:22-23
>"Turn to me and be saved, all the ends of the earth! For I am God, and there is no other. By myself I have sworn; from my mouth has gone out in righteousness a word that shall not return: ‘To me every knee shall bow, every tongue shall swear allegiance.’Micah 7:18-19
>Who is a God like you, pardoning iniquity and passing over transgression for the remnant of his inheritance? He does not retain his anger forever, because he delights in steadfast love. He will again have compassion on us; he will tread our iniquities underfoot. You will cast all our sins into the depths of the sea.Etc., etc.
Annhilationists have a decent number of passages they can point too, and our infernalist friends have helpfully already shared many of them and pretended that they support infernalism, e.g. "second death," could mean "being dead again, forever," as opposed to strangely meaning "living eternal life, but a very unpleasant one."
Infernalists have... Matthew 25, and the in Matthew 18 and Jude "eternal flame" is at least mentioned.
