Blasphemy
Speaking evil of God or denying Him some good which we should attribute to Him. Blasphemy of the Holy Spirit is stating that Jesus did his miracles by the power of the devil (Matt. 12:22-32) and is an unforgivable sin (Mark 3:28-30). Blasphemy arises out of pride (Psalm 73:9,11), hatred (Psalm 74:18), injustice (Isaiah 52:5), etc. Christ was mistakenly accused of blasphemy (John 10:30-33).
