“They Punished According to Their Crimes”

Joseph F. McConkie, Robert L. Millet
If the laws under King Benjamin were like those established by his son Mosiah, there was no law against a man’s belief (even false beliefs -see Alma 1:17; Alma 30:7), no crime committed in the perpetuation of error, except as these heresies resulted in a defiance or transgression of the legal code.
