Therefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Spirit shall not be forgiven unto men.
All Commentaries on Matthew 12:31 Go To Matthew 12
John Chrysostom
AD 407
But to me He seems here to be hinting also at the Jews, setting them on the devil's side. For they too were against Him, and were scattering what He gathered. As to the fact that He was hinting at them also.
Thus having defended Himself, and refuted their objection, and proved the vanity of their shameless dealings, He proceeds to alarm them. For this too is no small part of advice and correction, not only to plead and persuade, but to threaten also; which He does in many passages, when making laws and giving counsel.
And though the saying seem to have much obscurity, yet if we attend, its solution will prove easy.
What now is it that He affirms? Many things have ye spoken against me; that I am a deceiver, an adversary of God. These things I forgive you on your repentance, and exact no penalty of you; but blasphemy against the Spirit shall not be forgiven, no, not to those who repent. And how can this be right? For even this was forgiven upon repentance. Many at least of those who said these words believed afterward, and all was forgiven them. What is it then that He says? That this sin is above all things unpardonable. Why so? Because Himself indeed they knew not, who He might be, but of the Spirit they received ample experience. For the prophets also by the Spirit said whatever they said; and indeed all in the Old Testament had a very high notion of Him.
What He says, then, is this: Be it so: you are offended at me, because of the flesh with which I am encompassed: can you say of the Spirit also, We know it not? And therefore is your blasphemy unpardonable, and both here and hereafter shall you suffer punishment. For many indeed have been punished here only (as he who had committed fornication, as they who partook unworthily of the mysteries, among the Corinthians); but you, both here and hereafter.
