“But whoever blasphemes

Against the Holy Spirit

Can never have forgiveness.

But he is guilty

Of an eternal sin.”

 

ὃς δ’ ἂν βλασφημήσῃ εἰς τὸ Πνεῦμα τὸ Ἅγιον, οὐκ ἔχει ἄφεσιν εἰς τὸν αἰῶνα, ἀλλὰ ἔνοχός ἐστιν αἰωνίου ἁμαρτήματος.

 

There are similar statements to this in Matthew, chapter 12:31, and Luke, chapter 12:10.  Both Matthew and Luke said that it might be okay to disrespect the Son of Man, but it was quite another thing to speak against or blasphemy the Holy Spirit.  Blasphemy was profaning the name of God.  If you profaned the Holy Spirit, you were hopeless.  If you gave up on God and his Spirit, there was no hope of forgiveness.  God would forgive all human sins and blasphemies.  Whoever blasphemed against the Holy Spirit (ὃς δ’ ἂν βλασφημήσῃ εἰς τὸ Πνεῦμα τὸ Ἅγιον), would never be forgiven even in eternity (οὐκ ἔχει ἄφεσιν εἰς τὸν αἰῶνα).  He would be guilty of an eternal sin (ἀλλὰ ἔνοχός ἐστιν αἰωνίου ἁμαρτήματος). Anyone who spoke against the Holy Spirit would not be forgiven either now or in the future.
