There are many people who are committing the most serious sin, that of blaspheming the Holy
Spirit. Some are atheists, some are pagans, some are those of man-made religions, some are Catholics.
Some Catholics daily blaspheme the Holy Spirit sit next to us in Church, live in our families, teach in Catholic schools, speak from the pulpit.
What does it mean to blaspheme against the Holy Spirit? The CCC notes, 1864 "Therefore I tell you, every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will not be forgiven."136 There are no limits to the mercy of God, but anyone who deliberately refuses to accept his mercy by repenting, rejects the forgiveness of his sins and the salvation offered by the Holy Spirit.137 Such hardness of heart can lead to final impenitence and eternal loss.
What does this mean? Why is this sin so serious?
This sin is the absolute rejection of salvation, the total rejection of repentance and accepting Christ as Savior.
This sin is the non-acceptance of forgiveness, thinking that one's sins are too horrible for forgiveness.
It is a sin which is based on obstinacy, despair, envy, resistance to Truth, Who is a Person.
Why is this sin so serious? Because all people are given grace to repent. All. No one is not given grace sufficient to repentance.
It is a serious sin, as it denies Christ Himself as Savior, as King, as Messiah, as God.
Pray for those around us who are tempted or even living in this great sin. Pray.
Mark 3:22-30
Douay-Rheims 1899 American Edition (DRA)
22 And the scribes who were come down from Jerusalem, said: He hath Beelzebub, and by the prince of devils he casteth out devils.
23 And after he had called them together, he said to them in parables: How can Satan cast out Satan?
24 And if a kingdom be divided against itself, that kingdom cannot stand.
25 And if a house be divided against itself, that house cannot stand.
26 And if Satan be risen up against himself, he is divided, and cannot stand, but hath an end.
27 No man can enter into the house of a strong man and rob him of his goods, unless he first bind the strong man, and then shall he plunder his house.
28 Amen I say to you, that all sins shall be forgiven unto the sons of men, and the blasphemies wherewith they shall blaspheme:
29 But he that shall blaspheme against the Holy Ghost, shall never have forgiveness, but shall be guilty of an everlasting sin.
30 Because they said: He hath an unclean spirit.
