I have heard this term used for certain sins, murder, depriving the poor of justice… in the Catholic Church.
What does it mean? Is this a sin that cannot be forgiven? Is it harder to get absolution for these sins than for other sins? Is it impossible to get an indulgence for the temporal penalty for these sins?
I have also heard some say (based, I think, in part on Dante’s depiction of Purgatorio and partly on Revelation 22:15) that there are some who will be forgiven their sins and saved from Hell but denied the Beatific Vision, or who will only experience the ‘earthly paradise’ but not spend eternity with God (how could anything bring us eternal happiness unless we were with God?) Is this doctrine, or even T/tradition?
What are these sins? What if I have already committed one of them? What do I do? Do we know for certain that there are some who can never be forgiven?
