Eternal sin
In Christian hamartiology, eternal sins, unforgivable sins, unpardonable sins, or ultimate sins are sins which will not be forgiven by God. 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 unforgivable sin is interpreted by Christian theologians in various ways, although they generally agree that one who has committed the sin is no longer able to  repent, and so one who is fearful that they have committed it has not done so. New Testament passages. Several passages in the New Testament are frequently interpreted as referring to the unforgivable sin: Teaching by Christian denomination. Eastern Christianity. The importance of prayer (1 Thessalonians 5:17: "pray without ceasing") and humility (Jesus Prayer: "Lord Jesus Christ, Son of God, have mercy on me, a sinner") in Christianity is reflected by an Orthodox catechism as follows: Roman Catholicism. The Catechism of the Catholic Church teaches that, while no sin is absolutely "unforgivable", some sins represent a deliberate refusal to repent  and accept the infinite mercy of God; a person committing such a sin refuses God's forgiveness, which can lead to self-condemnation to Hell. In other words, one damns oneself by final impenitence (refusal to repent), as taught by John Paul II: The images of hell that Sacred Scripture presents to us must be correctly interpreted...hell indicates the state of those who freely and definitively separate themselves from God..."To die in mortal sin without repenting and accepting God's merciful love means remaining separated from him for ever by our own free choice. This state of definitive  self-exclusion from communion with God and the blessed is called 'hell'"..."Eternal damnation", therefore, is not attributed to God's initiative because in his merciful love he can only desire the salvation of the beings he created. In reality, it is the creature who closes himself to his love. Damnation consists precisely in definitive separation from God, freely chosen by the human person and confirmed with death that seals his choice for ever. God's judgement ratifies this state. In the context of the Gospels of Matthew and Mark, blasphemy against the Spirit is the sin of attributing to  Satan what is the work of the Spirit of God, such as when the Pharisees earlier accused Jesus of driving out demons only by the power of Beelzebul, the prince of demons. The Catholic Encyclopedia cites Matthew 12:22–32; Mark 3:22–30; Luke 12:10 (cf. 11:14–23) and defines "the unforgivable sin"—or sin against the Holy Ghost—as follows: ″... to sin against the Holy Ghost is to confound Him with the spirit of evil, it is to deny, from pure malice, the Divine character of works manifestly Divine.″ The article further states that "sin against the Son of Man" may be forgiven because  it is committed against the human person of Christ, which veils the Divine with a "humble and lowly appearance," and therefore such sin is excusable because it is committed through "man's ignorance and misunderstanding." The Church Fathers considered additional interpretations, Augustine of Hippo calling it one of the more difficult passages of Scripture. Thomas Aquinas summarized the Church Fathers' treatments and proposed three possible explanations: Thomas Aquinas lists, or has responded to, six sins that go against the Holy Spirit: Thomas Aquinas explains that the unforgivability of blasphemy against the Holy Spirit means that it removes the entrance to  these means of salvation; however, it cannot hinder God in taking away this obstacle by way of a miracle. However, the Church further believes there is no offence, however serious, that cannot be taken away by Baptism, or absolved from in the Confessional—that no one, however wicked and guilty, may not confidently hope for forgiveness. The Catechism says that Christ desires "the gates of forgiveness should always be open to anyone who turns away from sin." As did St Augustine, the Catholic Church today teaches that only dying unrepentant for one's sins is the only unforgivable  sin. Indeed, in "Dominum et vivificantem" Pope John Paul II writes "According to such an exegesis, 'blasphemy' does not properly consist in offending against the Holy Spirit in words; it consists rather in the refusal to accept the salvation which God offers to man through the Holy Spirit, working through the power of the Cross", and "If Jesus says that blasphemy against the Holy Spirit cannot be forgiven either in this life or in the next, it is because this "non-forgiveness" is linked, as to its cause, to "non-repentance," in other words to the radical refusal to  be converted. This means the refusal to come to the sources of Redemption, which nevertheless remain "always" open in the economy of salvation in which the mission of the Holy Spirit is accomplished." Reformed. John Calvin, the founder of the Reformed tradition of Christianity (which includes the Continental Reformed, Presbyterian, Congregationalist and Reformed Anglican denominations) wrote: Classical Arminian and Wesleyan Arminian. Jacob Arminius defined the unforgivable sin as "the rejection and refusing of Jesus Christ through determined malice and hatred against Christ". However, Arminius differed with Calvin in believing that the sin could be committed by believers, a conclusion he  reached through his interpretation of . John Wesley, the father of the Methodist (Wesleyan-Arminian) tradition, discussed the unforgivable sin in a sermon titled "A Call to Backsliders", in which he wrote that "that this blasphemy is absolutely unpardonable; and that, consequently, for those who have been guilty of this, God 'will be no more entreated'." A prominent Methodist catechism, "A Catechism on the Christian Religion: The Doctrines of Christianity with Special Emphasis on Wesleyan Concepts" states: This Wesleyan-Arminian interpretation of the unforgivable sin includes the deliberate labeling of good as evil, as rejecting the conviction of the Holy Spirit , of publicly attributing the work of the Holy Spirit to Satan, and attributing the work of Jesus to Satan. The United Methodist Church, a Methodist connexion, thus teaches: Latter-day Saints. Members of The Church of Jesus Christ of Latter-day Saints, also nicknamed Mormons, have a similar understanding of eternal sin. Joseph Smith, the founder of the Latter Day Saint movement, said in the King Follett discourse: Church apostle and later President of the Church, Spencer W. Kimball, stated that "the sin against the Holy Ghost requires such knowledge that it is manifestly impossible for the rank and file  [of the church] to commit such a sin". In Judaism. A very similar, although not identical, parallel to Matthew 12:31-32 can be found in the Avot of Rabbi Natan:
