sins against the Holy Spirit
sins against the Holy Spirit
Sins that embody a stubborn resistance to the inspirations of the Holy Spirit and an open contempt for his gifts. They are
despair of one’s salvation
presumption of God’s mercy
impugning the known truths of faith
envy of another’s spiritual good
obstinacy in sin
final impenitence
Although no sin is absolutely unpardonable, those who sin against the Holy Ghost stubbornly resist the influence of grace and do not wish to repent. Hence their sin cannot be forgiven them.
