Yesterday at church the speaker reminded us that the fall is our inheritance from Adam, on good scriptural authority.
That is to say, Mormons believe in original sin, we just happen to believe that Christ atones for it for all.
It’s not fair to punish the children for the sins of their fathers, no doubt. Any more than it is fair to make Christ atone for those inherited sins.
But inheritance is relationship. If we didn’t inherit anything from Adam, we wouldn’t be bound to him in anyway. And Christ’s act binds us to him.
As Mosiah understood, fairness–justice–leaves us alone, miserable, and even uncreated.
Thank God that life is unfair.
