Korihor Blasphemes
Alma 30:30
30 And it came to pass that when he was brought before Alma and the chief judge, he did go on in the same manner as he did in the land of Gideon; yea, he went on to blaspheme.
Elder Bruce R. McConkie wrote:
“Blasphemy consists in either or both of the following: 1. Speaking irreverently, evilly, abusively, or scurrilously against God or sacred things; or 2. Speaking profanely or falsely about Deity. Among a great host of impious and sacrilegious speaking that constitute blasphemy are such things as: Taking the name of God in vain; evil-speaking about the Lord’s anointed; belittling sacred temple ordinances, or patriarchal blessings, or sacramental administrations; claiming unwarranted divine authority; and promulgating with profane piety a false system of salvation.”
