Except for one thing you forgot!
Matthew 12:31 For this reason I say unto you, Every sin and injurious speaking shall be forgiven to men, but speaking injuriously of the Spirit shall not be forgiven to men.
Mat 12:32 And whosoever shall have spoken a word against the Son of man, it shall be forgiven him; but whosoever shall speak against the Holy Spirit, it shall not be forgiven him, neither in this age nor in the coming one .
Matthew 12:31, And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come.
What is the consequence that will not be pardoned (or “let off”, Lk.12:10) for blaspheming the Holy Spirit? Luke 12:10 doesn't say. Could it be death, whether in “this age or in the age to come” (Mt.12:32), e.g. the millennium? Perhaps an imminent or immediate death, and or divinely sanctioned capital punishment. A death that ends their opportunity for salvation by grace in their mortal life & ships them off to corrective punishment, such as in a place the rich man (Luke 16:19-31) went to? For as long as it takes. Consider the following passages of Scripture where death is the penalty for blasphemy that the blasphemers were not pardoned from:
27 Also if one person sins unintentionally, then he shall offer a one year old female goat for a sin offering. 28 The priest shall make atonement before the LORD for the person who goes astray when he sins unintentionally, making atonement for him that he may be forgiven. 29 You shall have one law for him who does anything unintentionally, for him who is native among the sons of Israel and for the alien who sojourns among them. 30 But the person who does anything defiantly, whether he is native or an alien, that one is blaspheming the LORD; and that person shall be cut off from among his people. 31‘Because he has despised the word of the LORD and has broken His commandment, that person shall be completely cut off; his guilt will be on him.’” (Numbers 15:27-31)
Moreover, the one who blasphemes the name of the LORD shall surely be put to death; all the congregation shall certainly stone him. The alien as well as the native, when he blasphemes the Name, shall be put to death. (Leviticus 24:16)
28 A man that hath set at nought Moses’ law dieth without compassion on the word of two or three witnesses: 29 of how much sorer punishment, think ye, shall he be judged worthy, who hath trodden under foot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace? (Hebrews 10:28-29)
Compare also these Scripture passages referring to death as the penalty that was not pardoned:
But Peter said, Ananias, why hath Satan filled thine heart to lie to the Holy Spirit…why hast thou conceived this thing in thine heart? thou hast not lied unto men, but unto God. 5 And Ananias hearing these words fell down, and gave up the ghost… Then Peter said unto her, How is it that ye have agreed together to tempt the Spirit of the Lord? behold, the feet of them which have buried thy husband are at the door, and shall carry thee out. 10 Then fell she down straightway at his feet, and yielded up the ghost (Acts 5:3-6, 9-10).
If anyone sees his brother committing a sin not leading to death, he shall ask, and God will give him life—to those who commit sins that do not lead to death. There is sin that leads to death; I do not say that one should pray for that. (1 John 5:16)
But the LORD of hosts revealed Himself to me, “Surely this iniquity shall not be pardoned you Until you die,” says the Lord GOD of hosts. (Isaiah 22:14)
20 "Never again will there be in it an infant who lives but a few days, or an old man who does not live out his years; the one who dies at a hundred will be thought a mere child; the one who fails to reach a hundred will be considered accursed. (Isaiah 65:20)
Luke says it won’t be forgiven.
The Greek word for "forgiven" has a number of different meanings. It is used of Satan in regards to Jesus in Matthew 4:11. If you translate it as "forgive" there then you get a reading of "the devil did FORGIVE Him".
Here are various meanings given for the Greek word, APHIEMI (Strongs #863):
"Usage: (a) I send away, (b) I let go, release, permit to depart, (c) I remit, forgive, (d) I permit, suffer."
Strong's Greek: 863. ἀφίημι (aphiémi) -- to send away, leave alone, permit
Remit: "to cancel or refrain from inflicting // remit the penalty"
Definition of REMIT
Remit: "cancel or refrain from exacting or inflicting (a debt or punishment)."
"An example of remit is to pardon someone..."
So according to Luke 12:10 there is one sin for which a person won't be "let go" or "released" or "remitted", "pardoned", etc.. What he will not be "let go" of, or not "released" from, or not "remitted" or "pardoned" of, is not stated in Lk.12:10.
Therefore to conclude that such a sin will result in never ending punishment & the person can never be saved is to read something into the verse which is not stated. Consequently Lk.12:10 fails as a "proof text" against Biblical universalism. It's just that simple.
Mark says it won’t be forgiven in this world or the next.
Perhaps you meant Matthew. But Matthew 12:31-32 does not use the Greek word for "world", which is KOSMOS, but a form of the Greek word AION, meaning "age" or eon".
Those who commit the sin of Spirit blasphemy won't be "let off" or "released" or "remitted" from the due penalty or consequence for that sin. That consequence is what I detailed in my previous post to you, namely a "death" that sends people to "hell" until they are saved. That penalty or consequence for Spirit blasphemy will not only apply in this "age" but also in the millennial age to come:
Isa.65:20 Never again will there be in it an infant who lives but a few days, or an old man who does not live out his years; the one who dies at a hundred will be thought a
mere child; the one who fails to reach a hundred will be considered accursed.
So death from this world obviously doesn’t pay for this sin if it is not forgiven in the next world.
Lk.12:10 & Mt.12:31-32 say nothing about anyone "pay[ing] for this sin". The verse isn't talking about being "forgiven" for this sin, but of a person who commits the sin not being "let go" or "released", which implies some consequences or penalty. What those consequences are, or what that penalty is, is not stated.
As my previous post showed, certain blasphemers in the Scriptures suffered death, either by stoning, or by other means. Whether or not they could ever be "forgiven" by God is not stated. But they were not to be "pardoned" or "let go" or "released" from the consequences or penalty which was required, e.g. being stoned to death.
We shouldn't ignore the Biblical context & references to blasphemy & the consequence of death when interpreting Jesus' words in Lk.12:10. He was speaking to Jews whose Scriptures were the Old Testament.
"When Jesus speaks of pardoning or forgiving a sin, he has in mind something utterly different from an attitude of forgiveness, which in God never ceases; he has in mind instead a release from some obligation, or a canceling of some debt, or a setting aside of some prescribed punishment. It is very close to our idea of forgiving a debt or pardoning a criminal. If a debt is unforgiven, then it must be paid; and once it is paid, it no longer exists. Similarly, if a criminal is unpardoned, then the criminal must serve his or her sentence; and once the sentence is served, there is no longer any need for a pardon. An unforgivable or unpardonable sin, therefore, need not be an uncorrectable sin at all; it is simply one that God cannot deal with adequately in the absence of an appropriate punishment."
"...when Jesus speaks of forgiveness in the present context, he has in mind, as we noted above, the canceling of some obligation, debt, or prescribed punishment."

Just what does it mean to say that God will never forgive or pardon a given sin
