Speaking disrespectfully or irreverently of God or sacred things.
Jesus was charged several times by the Jews with speaking blasphemy because He claimed the right to forgive sins (Matt. 9:2–3; Luke 5:20–21), because He called Himself the Son of God (John 10:22–36; 19:7), and because He said they would see Him sitting on the right hand of power and coming in the clouds of heaven (Matt. 26:64–65). These charges would have been true if He had not actually been all that He said He was. The charge brought against Him by the false witnesses at the trial before the Sanhedrin (Matt. 26:59–61) was of blasphemy against God’s temple. Blasphemy against the Holy Ghost, which is willfully denying Christ after having received a perfect knowledge of Him, is the unforgivable sin (Matt. 12:31–32; Mark 3:28–29; D&C 132:27).
