Eternal sin
In Catholic teaching there are six sins that blaspheme against the Holy Spirit. They are: Several passages in the Bible are frequently interpreted as referring to the unforgivable sin:
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.
