A: There are many sins recounted in the Hebrew Bible but none are ever called unforgivable sins.
One eternal or unforgivable sin (blasphemy against the Holy Spirit), also known as the sin unto death, is specified in several passages of the Synoptic Gospels, including Mark 3:28–29, Matthew 12:31–32, and Luke 12:10, as well as other New Testament passages including Hebrews 6:4–6, Hebrews 10:26–31, and 1 John 5:16.
“The sins against the Holy Ghost are commonly said to be six: despair, presumption, impenitence, obstinacy, resisting truth, and envy of another's spiritual welfare.” Clearly, all of them are rooted in hardness of heart without any indication that the person desires to amend his or her life.
In Mark 3:29 Jesus says that “whoever blasphemes against the Holy Spirit will never be forgiven; they are guilty of an eternal sin.” Matthew's account adds that even blasphemy against the Son of Man will be forgiven, but not blasphemy against the Holy Spirit (Matthew 12:31–32).
That is surely the significance of our Lord's words about “gnashing of teeth” (Matthew 8:12; 13:42, 50; 22:13; 24:51; 25:30). There are three sins that lie behind discontent—pride, rebellion and unbelief. These are the original sins of the devil and his angels.
Pride (superbia), also known as hubris (from Ancient Greek ὕβρις) or futility. It is considered the original and worst of the seven deadly sins on almost every list, the most demonic.
Of the seven deadly sins, theologians and philosophers reserve a special place for pride. Lust, envy, anger, greed, gluttony and sloth are all bad, the sages say, but pride is the deadliest of all, the root of all evil, and the beginning of sin.
In the Book of Matthew (12: 31-32), we read, "Therefore I say to you, any sin and blasphemy shall be forgiven men, but blasphemy against the Spirit shall not be forgiven.
Therefore I tell you, every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will not be forgiven. And whoever says a word against the Son of man will be forgiven; but whoever speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come" (Matthew 12:22-32).
The three Unforgivable Curses are the Cruciatus Curse, which causes unbearable pain; the Imperius Curse, which allows the user to control the actions of the victim; and the Killing Curse, which causes instant death.
The Catholic Church teaches explicitly that there is no sin, no matter how serious, that cannot be forgiven (Catechism of the Catholic Church). To imply otherwise is a challenge to God's omnipotence. God's mercy is more powerful than any human ability to do evil. However, humans also have free will.
— J.F.D. Rev. Graham: Only one sin that can't be forgiven is on God's list — and that is the sin of rejecting Him and refusing His offer of forgiveness and new life in Jesus Christ. This alone is the unforgivable sin, because it means we are saying that the Holy Spirit's witness about Jesus is a lie (see Luke 12:10).
Therefore, when others ask, “Can a Christian commit the unpardonable sin?” the clearest answer is “no,” because to be a follower of Jesus is to believe and accept the testimony of the Spirit – that Christ is Lord – which is the exact opposite of the Pharisees' response.
These sins are vices and are defined as contrary to the Christian virtues of holiness. They are pride, avarice, envy, wrath, lust, gluttony, and sloth (acedia).
The Bible says, "If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness" (1 John 1:9).
Spitting on a cross, drawing pictures in the Qur'an, tripping a rabbi—all of these are rude in general, but because they combine a sacred religious person or thing with rude behavior, they're also blasphemous.
Original sin, according to Augustine, consists of the guilt of Adam that all humans inherit.
Envy is considered one of the “seven deadly sins.” And for good reason. If covetousness is desiring another person's traits, status, abilities or rewards for yourself, envy takes it a step further. It's not only desiring that for yourself but wanting to deprive the other person from having it.
There are six things the Lord hates, seven that are detestable to him: haughty eyes, a lying tongue, hands that shed innocent blood, a heart that devises wicked schemes, feet that are quick to rush into evil, a false witness who pours out lies and a person who stirs up conflict in the community.
There are two things to remember here: (1) God's mercy is indeed infinite, and (2) true repentance means forsaking your sins. On the one hand, because of the infinite Atonement of Jesus Christ, repentance is available to everyone, even those who have made the same mistakes many times.
Imperio - The Imperius Curse.
The three curses that are classified as Unforgivable are the Imperius Curse, the Cruciatus Curse, and the Killing Curse. Mad-Eye Moody introduces Harry and his class to these curses in Harry Potter and the Goblet of Fire.
The Unforgivable Curses are curses so powerful and so malign that use of them on another human being is grounds for immediate life imprisonment in Azkaban Prison.
Resisting the Imperius Curse was possible, but extremely difficult. Only those of a particularly strong will could achieve it. Harry Potter, Barty Crouch Snr, and Barty Crouch Jnr each learned to resist the curse after being subjected to its effects.
