The Sin Against the Holy Spirit

Commentary of the day : Blessed John-Paul II
The sin against the Holy Spirit
"Blasphemy against the Holy Spirit, then, is the sin committed by the person who claims to have a "right" to persist in evil - in any sin at all - and who thus rejects Redemption. One closes oneself up in sin, thus making impossible one's conversion, and consequently the remission of sins, which one considers not essential or not important for one's life. This is a state of spiritual ruin, because blasphemy against the Holy Spirit does not allow one to escape from one's self-imposed imprisonment. "

Holy Gospel of Jesus Christ according to Saint Mark 3:22-30.
The scribes who had come from Jerusalem said of Jesus, "He is possessed by Beelzebul," and "By the prince of demons he drives out demons."
Summoning them, he began to speak to them in parables, "How can Satan drive out Satan?
If a kingdom is divided against itself, that kingdom cannot stand.
And if a house is divided against itself, that house will not stand.
 And if Satan has risen up against himself and is divided, he cannot stand; that is the end of him.
But no one can enter a strong man's house to plunder his property unless he first ties up the strong man. Then he can plunder his house.
Amen, I say to you, all sins and all blasphemies that people utter will be forgiven them.
But whoever blasphemes against the holy Spirit will never have forgiveness, but is guilty of an everlasting sin."
For they had said, "He has an unclean spirit."
