The revelation then called Oliver to go nearly a thousand miles to the western edge of the United States to preach the restored gospel to American Indians, who were remnants of the house of Israel. The Lord said that the city of Zion would be built near these people, echoing the Book of Mormon’s promise that God would establish the New Jerusalem on the American continent prior to the Second Coming of Christ. He did not identify the city’s exact location, but He promised to reveal that information at a later time.20
D&C 28:8 And now, behold, I say unto you that you shall go unto the Lamanites and preach my gospel unto them; and inasmuch as they receive thy teachings thou shalt cause my church to be established among them; and thou shalt have revelations, but write them not by way of commandment.
9 And now, behold, I say unto you that it is not revealed, and no man knoweth where the city Zion shall be built, but it shall be given hereafter. Behold, I say unto you that it shall be on the borders by the Lamanites.
Notice the difference?
The term "Indians" is not found in any of the scriptures, but Saints creates a false historical narrative by telling us Oliver was called to preach to "American Indians" instead of what the scriptures say: "Lamanites."
This is a deliberate change of wording from the scriptures. Note 20 mentions the change from the original to the publication.
20. Knight, Autobiography, 145–47; Doctrine and Covenants 28 (Revelation, Sept. 1830–B, at josephsmithpapers.org); Covenant of Oliver Cowdery and Others, Oct. 17, 1830, in JSP, D1:204; see also Doctrine and Covenants 29 (Revelation, Sept. 1830–A, at josephsmithpapers.org); 3 Nephi 21:23–24; and Ether 13:3–10. The revelation said the place for the holy city would be “among the Lamanites” but was edited for publication to read “on the borders by the Lamanites.” (Book of Commandments 30:9, in JSP, R2:80.) Topics: American Indians; Zion/New Jerusalem; Gathering of Israel.
D&C 30:5 Behold, I say unto you, Peter, that you shall take your journey with your brother Oliver; for the time has come that it is expedient in me that you shall open your mouth to declare my gospel; therefore, fear not, but give heed unto the words and advice of your brother, which he shall give you.
6 And be you afflicted in all his afflictions, ever lifting up your heart unto me in prayer and faith, for his and your deliverance; for I have given unto him power to build up my church among the Lamanites;
D&C 32:1 And now concerning my servant Parley P. Pratt, behold, I say unto him that as I live I will that he shall declare my gospel and learn of me, and be meek and lowly of heart.
2 And that which I have appointed unto him is that he shall ago with my servants, Oliver Cowdery and Peter Whitmer, Jun., into the wilderness among the Lamanites.
Nevertheless, on page 105, Saints tells us Oliver was thinking about American Indians, not Lamanites.
As pleased as he was with their success in Ohio, though, Oliver knew the Lord had called them to preach to the American Indians who lived beyond the western border of the United States.
Here again, Saints is creating a false historical narrative by changing the wording of the historical record to accommodate a modern theory of Book of Mormon geography.
This isn't the biggest problem with Saints, but it's another unforced error. I think we'd all be much better off if Saints had stuck with the language of the scriptures instead of creating a false historical narrative to accommodate M2C.
