13 O ye that are bound down under a foolish and a vain hope, why do ye yoke yourselves with such foolish things? Why do ye look for a Christ? For no man can know of anything which is to come.
14 Behold, these things which ye call prophecies, which ye say are handed down by holy prophets, behold, they are foolish traditions of your fathers.
15 How do ye know of their surety? Behold, ye cannot know of things which ye do not see; therefore ye cannot know that there shall be a Christ.
16 Ye look forward and say that ye see a remission of your sins. But behold, it is the effect of a frenzied mind; and this derangement of your minds comes because of the traditions of your fathers, which lead you away into a belief of things which are not so.
17 And many more such things did he say unto them, telling them that there could be no atonement made for the sins of men, but every man fared in this life according to the management of the creature; therefore every man prospered according to his genius, and that every man conquered according to his strength; and whatsoever a man did was no crime.
18 And thus he did preach unto them, leading away the hearts of many, causing them to lift up their heads in their wickedness, yea, leading away many women, and also men, to commit whoredoms—telling them that when a man was dead, that was the end thereof. ...
23 And Korihor said unto [Gideon]: Because I do not teach the foolish traditions of your fathers, and because I do not teach this people to bind themselves down under the foolish ordinances and performances which are laid down by ancient priests, to usurp power and authority over them, to keep them in ignorance, that they may not lift up their heads, but be brought down according to thy words.
24 Ye say that this people is a free people. Behold, I say they are in bondage. Ye say that those ancient prophecies are true. Behold, I say that ye do not know that they are true.
25 Ye say that this people is a guilty and a fallen people, because of the transgression of a parent. Behold, I say that a child is not guilty because of its parents.
26 And ye also say that Christ shall come. But behold, I say that ye do not know that there shall be a Christ. And ye say also that he shall be slain for the sins of the world—
27 And thus ye lead away this people after the foolish traditions of your fathers, and according to your own desires; and ye keep them down, even as it were in bondage, that ye may glut yourselves with the labors of their hands, that they durst not look up with boldness, and that they durst not enjoy their rights and privileges.
28 Yea, they durst not make use of that which is their own lest they should offend their priests, who do yoke them according to their desires, and have brought them to believe, by their traditions and their dreams and their whims and their visions and their pretended mysteries, that they should, if they did not do according to their words, offend some unknown being, who they say is God—a being who never has been seen or known, who never was nor ever will be. ...
31 And [Korihor] did rise up in great swelling words before Alma, and did revile against the priests and teachers, accusing them of leading away the people after the silly traditions of their fathers, for the sake of glutting on the labors of the people. ...
37 And then Alma said unto him: Believest thou that there is a God?
38 And he answered, Nay. ...
43 And now Korihor said unto Alma: If thou wilt show me a sign, that I may be convinced that there is a God, yea, show unto me that he hath power, and then will I be convinced of the truth of thy words. ...
45 ...Yea, I will deny, except ye shall show me a sign.
46 And now it came to pass that Alma said unto him: ...
47 ... therefore if thou shalt deny again, behold God shall smite thee, that thou shalt become dumb, that thou shalt never open thy mouth any more, that thou shalt not deceive this people any more.
48 Now Korihor said unto him: I do not deny the existence of a God, but I do not believe that there is a God; and I say also, that ye do not know that there is a God; and except ye show me a sign, I will not believe.
49 Now Alma said unto him: This will I give unto thee for a sign, that thou shalt be struck dumb, according to my words; and I say, that in the name of God, ye shall be struck dumb, that ye shall no more have utterance.
