I watched a movie about Brigham Young and Joseph Smith called the Savage Journey - In the movie Joseph Smith talks to the angry crowd after a group of Mormon women and children are brutally murdered, (not the Meadows incident but similar) and afterwards he is taken into custody by the authorities because he smashed a printing press. I guess it was because he linked the press to the public outrage against Mormons. Anyway, while he was being taken in for questioning he warned of disaster describing the war between the north and the southern states.
It was also stated that the Mormon church was against slavery.
I'm checking on it right now. I will post my findings and revise the post later after I find out. (very interesting stuff!)
The Prophesy Given by Joseph Smith
The prophecy was given 25 December 1832 and is given in Doctrine and Covenants 87:1-8
1 VERILY, thus saith the Lord concerning the wars that will shortly come to pass, beginning at the rebellion of South Carolina, which will eventually terminate in the death and misery of many souls;
2 And the time will come that war will be poured out upon all nations, beginning at this place.
3 For behold, the Southern States shall be divided against the Northern States, and the Southern States will call on other nations, even the nation of Great Britain, as it is called, and they shall also call upon other nations, in order to defend themselves against other nations; and then war shall be poured out upon all nations.
4 And it shall come to pass, after many days, slaves shall rise up against their masters, who shall be marshaled and disciplined for war.
5 And it shall come to pass also that the remnants who are left of the land will marshal themselves, and shall become exceedingly angry, and shall vex the Gentiles with a sore vexation.
6 And thus, with the sword and by bloodshed the inhabitants of the earth shall mourn; and with famine, and plague, and earthquake, and the thunder of heaven, and the fierce and vivid lightning also, shall the inhabitants of the earth be made to feel the wrath, and indignation, and chastening hand of an Almighty God, until the consumption decreed hath made a full end of all nations;
7 That the cry of the saints, and of the blood of the saints, shall cease to come up into the ears of the Lord of Sabbath, from the earth, to be avenged of their enemies.
8 Wherefore, stand ye in holy places, and be not moved, until the day of the Lord come; for behold, it cometh quickly, saith the Lord. Amen. (D&C 87:1-8)
Text verse 5-8 Is actually about the Days of the Beast. The text concerning the Civil War is 1-4. So that you understand the meaning of the warning by Smith. As to the ends of men by their decrees of sin against principalities, including the holy spirit and the church.
It is established that consequences are predictable because of the sins of men. But it is the Prophet that has further insight and explanations to particular events. In this case Smith related the sins of the day to upheaval and related the two bloody wars to spiritual wrath from God. And in the days of the Beast those who stood their ground in the holy places lived through till the end when Christ did return to conquer the armies of the Beast. (As it is written in the book of Revelation. )
