If there is a people within the pales of this nation that is worthy of the constitution, good laws and institutions of the American Government, it is this people called Latter-day Saints. It is the best earthly Government that ever was framed by man, and the true and righteous are alone worthy of it. It cannot long be administered by wicked hands. “When the wicked rule, the people mourn” (D&C 98:9).
