Although I do wrong, I do not the wrongs that I am charged with doing: the wrong that I do is through the frailty of human nature, like other men. No man lives without fault. Do you think that even Jesus, if He were here, would be without fault in your eyes? His enemies said all manner of evil against Him—they all watched for iniquity in Him.

I … went over to the store [in Nauvoo, Illinois], where a number of brethren and sisters were assembled, who had arrived this morning from the neighborhood of New York. … I told them I was but a man, and they must not expect me to be perfect; if they expected perfection from me, I should expect it from them; but if they would bear with my infirmities and the infirmities of the brethren, I would likewise bear with their infirmities.
