<P> In Christian hamartiology, eternal sins, unforgivable sins, or unpardonable sins are sins which will not be forgiven by God . One eternal or unforgivable sin (blasphemy against the Holy Spirit) is specified in several passages of the Synoptic Gospels, including Mark 3: 28 - 29, Matthew 12: 31 - 32, and Luke 12: 10 . </P> <P> In Roman Catholic teaching there are six sins that blaspheme against the Holy Spirit . They are: 1 . Despair (believing that one's evil is beyond God's forgiveness); 2 . Presumption (glory without merit, that is, hope of salvation without keeping the Commandments, or expectation of pardon for sin without repentance); 3 . Envying the goodness of another (sadness or repining at another's growth in virtue and perfection); 4 . Obstinacy in sin (willful persisting in wickedness, and running on from sin to sin, after sufficient instructions and admonition); 5 . Final impenitence (to die without either confession or contrition for our sins), and 6 . Impugning the known truth (to argue against known points of faith, and this includes misrepresenting parts or all of the Christian faith to make it seem undesirable). </P>

In the bible is there an unforgivable sin
