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."
Confession (religion)
Within confession, the sinner must confess both to God and to those persons wronged by the sin. Confession may also be required to an authorized priesthood leader, such as a bishop, branch president, stake president, or mission president. Although there is no definitive list of sins that require confession to a priesthood leader, "adultery, fornication, other sexual transgressions and deviancies, and sins of a comparable seriousness" are included, as is intentional and repeated use of pornography. Depending on the seriousness of the sin, the priesthood leader may counsel the sinner to submit to the authority of a disciplinary council, but does not have the authority to forgive sin, which can come only from God. The confession to the priesthood leader must be held in strict confidence unless the confessor grants permission to disclose it to the disciplinary council. The LDS Church rejects the belief that confession is all that is required to secure repentance from God.
