Matthew 12:31 Blasphemy
And so I tell you, every kind of sin and slander can be forgiven, but blasphemy against the Spirit will not be forgiven.
In its technical English sense, signifies the speaking evil of God and in this sense it is found (Psalms 74:18; Isaiah 52:5; Romans 2:24) etc. But according to its derivation it may mean any species of calumny and abuse: see (1 Kings 21:10; Acts 18:6; Jude 1:9) etc. Blasphemy was punished by stoning, which was inflicted on the son of Shelomith. (Leviticus 24:11) On this charge both our Lord and St. Stephen were condemned to death by the Jews. The blasphemy against the Holy Ghost, (Matthew 12:32; Mark 3:28) consisted in attributing to the power of Satan those unquestionable miracles which Jesus performed by “the finger of God” and the power of the Holy Spirit. It is plainly such a state of wilful, determined opposition to God and the Holy Spirit that no efforts will avail to lead to repentance. Among the Jews it was a sin against God answering to treason in our times.
