D&C 42
He that committeth adultery after he has repented of the same shall not be forgiven. (two strikes and you’re out – verse 26)
Inasmuch as ye impart of your substance unto the poor, ye will do it unto me. (we need not wonder how to feed the hungry and clothe the naked; we need not guess if our offering is helping or hurting if we will impart through the established church – verse 31)
Those who kill shall have no forgiveness in this life. That does not dictate that they should die, but it vertainly prevents anyone from arguing that they should be spared on some doctrinal basis.
