There were many false claims by Joseph Smith and Brigham Young. One was that Zion would be built in America. Zion is and always will be Jerusalem, Israel. There are many more reasons to stay away from the BoM and other teachings by Smith and Co.
... the evidence is presented:
In 1976, the 137th section of Doctrine & Covenants (D&C) was submitted to the general conference of the Church of Jesus Christ of Latter-day Saints for a vote to be "sustained" as scripture. It is a narrative of a vision supposedly seen by Joseph Smith in Kirtland, OH in 1836.
What the members who voted on this new addition to scripture were not told by "the Brethren," is that whole paragraphs (216 words) of the actual revelation as recorded in The History of the Church had been conveniently left out of the version to be included in the D&C. The reason for these omissions was that four obviously false prophecies were contained in the part of the revelation that was censored out. These were prophecies so obviously false that even the average LDS reader would pick them up. Therefore, they went down the "black hole" of Mormon history.
What exactly were in these missing parts? Well, if you go to the official history of the LDS church published by the church's own publishing company, you will be easily able to find the missing prophecies. Here is what is not in the new D&C 137:
[Joseph Smith:] "....I saw the Twelve Apostles of the Lamb, who are now upon the earth, who hold the keys of this last ministry, in foreign lands, standing together in a circle, much fatigued, with their clothes tattered and their feet swollen, with their eyes cast downward, and Jesus standing in their midst, and they did not behold him. The Saviour looked upon them and wept.
I also beheld Elder M'Lellin in the south, standing upon a hill, surrounded by a vast multitude, preaching to them, and a lame man standing before him supported by his crutches; he threw them down at his word and leaped as a hart, by the mighty power of God.
Also, I saw Elder Brigham Young standing in a strange land, in the far south and west, in a desert place, upon a rock in the midst of a bout a dozen men of color, who appeared hostile. He was preaching to them in their own tongue, and the angel of God standing above his head with a drawn sword in his hand, protecting him, but he did not see it.
And I finally saw the Twelve in the celestial kingdom of God. I also beheld the redemption of Zion and many things which the tongue of man cannot describe in full"
Now, if this were true, it was a truly inspiring and wonderful declaration! Unfortunately, for the LDS faithful, a short look at the official history of the church reveals the false prophecies contained therein.
First of all, Smith claimed to see his (original LDS) Twelve apostles all in the celestial kingdom. This is difficult to imagine, since there was already division between Smith and the majority of the Apostles, beginning with discord in Kirtland, Ohio. The first portion of the "missing words" shows his less than subtle rebuke of their resistance to his will. "...fatigued....tattered...eyes cast downward....The Saviour looked upon them and wept." Smith was calling them to get into line and submit themselves to his full authority. That's the carrot offered in the last portion, "I finally saw the Twelve in the Celestial Kingdom of God."
However, his "thus saith the Lord" must have had little effect on them, since at least seven of the twelve under discussion were soon excommunicated or apostatized from the church: John F. Boynton & Luke S. Johnson (1837), Lyman Johnson (1838), William E. M'Lellin (c.1838), Thomas B. Marsh & Orson Hyde (1838), and William Smith (1845)
How could they have ever attained the celestial kingdom under those conditions? They couldn't! They were not only accursed by their very acts of apostasy or excommunication, but fell victim to the LDS Church's own scriptural denunciation. D&C 84.40-41 clearly states:
"Therefore, all those who receive the priesthood, receive this oath and covenant of my father, which he cannot break, neither can it be moved. But whoso breaketh this covenant after he hath received it, and altogether turneth there-from, shall not have forgiveness of sins in this world nor in the world to come."
Although a few of these men later returned to the church, none of them were even close to the standards necessary for attainment of that highest degree of glory. The majority remained apart for life. Therefore, the prophetic utterance, "I finally saw the Twelve in the Celestial Kingdom of God." was obviously false. It would have been false even if only one Apostle remained outside the fold.
Second, the vision of M'Lellin preaching and working miracles in the south never came true because he apostatized from the church without ever doing it! (See above).
Third, Although Brigham Young did bring the Mormons west and was a great colonizer and orator, the vision of Brigham Young preaching to "men of color" in their own language, in some strange and faraway place in the southwest never took place either, or at least there is no trace of it in the very detailed records and diaries concerning his reign as prophet.
Finally, "Zion" (Independence, MO.) was never redeemed, has never been redeemed in the 150+ years since the prophecy was made. (See below, for more on Zion). Is it any wonder that the Brethren chose to remove whole chunks of this "inspired" revelation?
Four false prophecies for the price of one! (from > http://saintsalive.com/resourcelibrary/mormonism/testing-the-prophecies-of-joseph-smith- )
We do not know whether or not some instructions through prophets were not included because they were judged to be false or unreliable.
Hold this thought...
