Heber C. Kimball's sermon acknowledging the split between Deseret and the U.S. government only 16 days after MMM.
Heber C. Kimball, "Spiritual Dissolution—Ignorance of the World," Journal of Discourses, 26 vols. (Liverpool: Asa Calkin, 1858), 5:275
We have declared our independence . . . when the time of the test comes, as the Lord God Almighty lives, if you then leave us or betray us, that is the end of you . . . This year’s trouble will not be much. It is not going to amount to a great deal; but it will amount to this—a collision between this people and the United States; and the gate will be shut down between us and them. This is already done to a certain extent; but many of you do not see it.
