Eternal sin
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."
Damnation
In most forms of Western Christian belief, damnation to hell is what humanity deserves for its sins. Catholic and many Protestant denominations hold that human sin is the product of the fall of man of Adam and Eve in the book of Genesis. In some Christian denominations, only the sins that the Ten Commandments describe cause damnation, but others apply more strict terms. The reasons for being damned have varied widely through the centuries, with little consistency between different forms of Christianity (i.e., Catholic or Protestant). "Sins" ranging from murder to dancing have been said to lead to damnation.
Christian denominations have differing views on soteriology, but a mainstream view is that believers can only escape damnation by salvation from Jesus Christ.
