What is the unforgivable sin?
Interpretations 25 to 33; all different.

"For if ye forgive men their trespasses, your heavenly Father will also forgive you: But if ye forgive not men their trespasses, neither will your Father forgive your trespasses."

Miano concludes:

"For if you forgive people their wrongdoing, your heavenly Father will forgive you as well. But if you don't forgive people, your Father will not forgive you your wrongdoing." ₁

"I read somewhere that the only unforgivable sin was to claim a state of sinless (which is often the theme of ultimate evil in literature and history) and although it seemed pretty lame at first, later after I had turned it over and over in my mind, I realized it was a pretty good checkmate to blocking out any sunlight of the spirit. ..." ₃

"... the unforgivable sin is plain and simple, rejection. I think it is final on Judgment Day when everything is before you, God, Jesus and the Holy Ghost and you still deny them. I think that is the unforgivable sin. Until then as long as we are sincere, all can be forgiven. ₃

"... we cannot arbitrarily decide which sins we think are heinous, and then simply attribute to them the property of being unpardonable ..." ₄

"There's some confusion over what an unpardonable sin would actually entail. Some think it's murder. Others think it's a second round of adultery after you've already played your first 'it was just a stupid mistake and won't happen again' card. Most Mormons think the unpardonable sin involves having your eyes opened to the truth of salvation  -- that is, getting the chance, even in hell, to choose faith -- but denying it anyway. Cold. That's blasphemy against the Holy Ghost, and it earns you eternity in fire and brimstone."
