Book of Mormon on Freedom of Belief

7 Now there was no law against a man’s belief; for it was strictly contrary to the commands of God that there should be a law which should bring men on to unequal grounds.

8 For thus saith the scripture: Choose ye this day, whom ye will serve.

9 Now if a man desired to serve God, it was his privilege; or rather, if he believed in God it was his privilege to serve him; but if he did not believe in him there was no law to punish him.

10 But if he murdered he was punished unto death; and if he robbed he was also punished; and if he stole he was also punished; and if he committed adultery he was also punished; yea, for all this wickedness they were punished.

11 For there was a law that men should be judged according to their crimes. Nevertheless, there was no law against a man’s belief; therefore, a man was punished only for the crimes which he had done; therefore all men were on equal grounds.—Alma 30:7-11
