Matthew 12:31 - Ellicott's Commentary On The Whole Bible

The blasphemy against the Holy Ghost. — Better, against the Spirit, the word “Holy” not being found in any MSS. of authority. The question, What is the nature of the terrible sin thus excluded from forgiveness? has, naturally enough, largely occupied the thoughts of men. What, we ask, is this blasphemy against the Holy Ghost? (1.) The context at least helps us to understand something of its nature. The Pharisees were warned against a sin to which they were drawing perilously near. To condemn the Christ as a gluttonous man and a wine-bibber, as breaking the Sabbath, or blaspheming when He said, “Thy sins be forgiven thee,” was to speak a word against the Son of Man. These offences might be sins of ignorance, not implying more than narrowness and prejudice. But to see a man delivered from the power of Satan unto God, to watch the work of the Spirit of God, and then to ascribe that work to the power of evil, this was to be out of sympathy with goodness and mercy altogether. In such a character there was no opening for repentance, and therefore none for forgiveness. The capacity for goodness in any form was destroyed by this kind of antagonism. (2.) We dare not say, and our Lord does not say it, that the Pharisees had actually committed this sin, but it was towards this that they were drifting. And in reference to later times, we may say that this is the ultimate stage of antagonism to God and to His truth, when the clearest proofs of divine power and goodness are distorted into evidence that the power is evil. The human nature in that extremest debasement has identified itself with the devil nature, and must share its doom.
