The concept of “blasphemy against the Spirit” is mentioned in Matthew 12:22–32 (see also Mark 3:22–30 and Luke 12:8–10). According to Matthew, Jesus had just performed a miracle. A demon-possessed man was brought to Jesus, and the Lord cast the demon out, healing the man of blindness and muteness. The eyewitnesses to this exorcism began to wonder if Jesus was indeed the Messiah they had been waiting for. A group of Pharisees, hearing the talk of the Messiah, quickly quashed any budding faith in the crowd: “It is only by Beelzebul, the prince of demons, that this fellow drives out demons,” they said (Matthew 12:24).
