I have really enjoyed writing detailed and extensive scriptural responses. Indeed, I am compiling our conversations to print out if time allows for those who would find them interesting as I do. However, it has become apparent that extended treatments have allowed you to ignore key points as if no effort was expended. So, I think I should refrain from the practice and address issues in more bite sized manner, that obvious avoiding issues will be apparent.

Proof in the Links

You insist that I should read certain Sections and portions thereon from the Doctrine and Covenants (which I have) that prove your points. The problem that this presents is that these revelations have been so edited that they have become unreliable. You cite David Whitmer as one of those whom Joseph introduced angels. This same Whitmer had the same concerns about editing revelations as I do.

Letter written by David Whitmer
Published in the Saints Herald, February 5, 1887

"Some of the revelations as they now appear in the Book of Doctrine and Covenants have been changed and added to changed and added to. Some of the changes being the greatest importance as the meaning is entirely changed on some very important matters; as if the Lord had changed his mind a few years after he gave the revelations, and after having commanded his servants (as they claim) to print them in the "Book of Commandments;" and after giving his servants a revelation, being a preface unto His Book of Commandments, which says: "Behold this is mine authority, and the authority of my servants, and my preface unto the Book of my Commandments, which I have given them to publish unto you, oh inhabitants of the earth." Also in this preface, "Behold I am God, and have spoken it; These commandments are of me." "Search these commandments, for they are true and faithful." The revelations were printed in the Book of Commandments correctly! This I know, and I will prove it to you.

"These revelations were arranged for publication by Bro. Joseph Smith, Sidney Rigdon, Orson Hyde and others, in Hiram, Ohio, while I was there; and were sent to Independence to be published, and were printed just exactly as they were arranged by Bro. Joseph and the others. And when the Book of Commandments was printed, Joseph and the church received it as being printed correctly. This I know. But in the winter of 1834 they saw that some of the revelations in the Book of Commandments had to be changed, because the heads of the church had gone too far, and had done things in which they had already gone ahead of some of the former revelations. So the book of "Doctrine and Covenants" was printed in 1835, and some of the revelations changed and added to.

The going back and editing what was claimed to be from the mouth of the Lord destroys any confidence in settling any question by appealing to the Book of Commandments or the Doctrine and Covenants. Beyond that, Ezekiel tells us there would be two, yes two sticks and Nephi said that the two books would be the Bible and the Book of Mormon.

The History of the Church, assumed to be Joseph Smith's Journal, is understood to have been highly edited. That reference, therefore, is tainted.

Clearly, the Book of Mormon was to supply any plain and precious parts of the Gospel of Christ lost. This idea should be familiar to you. What seems to have escaped you is that the Book of Mormon was to come forth with "the greater things" withheld. I imagine you would think the greater things are found in the Doctrine and Covenants. However, Mormon says the greater things are on the plates he was referencing.

And now there cannot be written in this book even a hundredth part of the things which Jesus did truly teach unto the people;
But behold the plates of Nephi do contain the more part of the things which he taught the people.
And these things have I written, which are a lesser part of the things which he taught the people; and I have written them to the intent that they may be brought again unto this people, from the Gentiles, according to the words which Jesus hath spoken.
And when they shall have received this, which is expedient that they should have first, to try their faith, and if it shall so be that they shall believe these things then shall the greater things be made manifest unto them.
And if it so be that they will not believe these things, then shall the greater things be withheld from them, unto their condemnation.
Behold, I was about to write them, all which were engraven upon the plates of Nephi, but the Lord forbade it, saying: I will try the faith of my people.

The question may be, What are these greater things? Are the greater things priesthoods, work for the dead, or covenant paths? Well, they would seem to be in the sealed portion. When will the greater things come forth? if it shall so be that they shall believe these things then shall the greater things be made manifest unto them. And if it so be that they will not believe these things, then shall the greater things be withheld from them. The next question is have we received those greater things? Well, we don't have the sealed portion. Apparently, that is because nobody believes the things in the Book of Mormon.

Could the greater things have been revealed without the sealed portion through Living Oracles? No. As section 84 was written, the Lord plainly states that the Book of Mormon and the Bible were treated lightly, that the church was lead by those with darkened minds and under condemnation and they shall remain under this condemnation until they repent and remember the new covenant, even the Book of Mormon and the Bible...

When did this darkening condemnation end? Well, as of October 1986 the Church was still under that condemnation. President Benson said "I reaffirm those words to you this day. Let us not remain under condemnation, with its scourge and judgment, by treating lightly this great and marvelous gift the Lord has given to us. Rather, let us win the promises associated with treasuring it up in our hearts".

How lightly has the Book of Mormon treated? I received one of your references with deep interest. Here are some tidbits from your link:

Early Mormons rarely quoted from the book in their speeches and writings; in one nineteenth-century LDS periodical, Elders’ Journal, the Bible was cited forty times more often than the Book of Mormon. Although early Mormons believed that the book was an authentically ancient record and that its miraculous appearance signaled that they were living in the “latter days,” they didn’t strongly emphasize its teachings. When the book was cited, it was usually to support the belief that the LDS Church was the restoration of Israel. It wasn’t until 1961 that a year-long course in the Book of Mormon became required for freshman students at Brigham Young University, and it was the 1980’s before the Book of Mormon was cited regularly in General Conference talks by church leaders. (LDS author Jana Reiss )

Joseph Smith did not refer to passages from the book in his writings or sermons, nor was it cited very often by early church leaders. (LDS Professor Grant Hardy)

As a young missionary in the 1950s, before the standardized missionary plan was prepared, we had a discussion on the Book of Mormon, in which we told the people about the book and invited them to put Moroni’s promise to the test. We did not teach from the Book of Mormon, nor did we really refer to it after that. (LDS Professor Philip R. Kunz)

It has often been pointed out, however, that those beliefs most commonly associated with Mormonism are nowhere to be found in that text. Those expecting an exposition of peculiarly Mormon doctrine will be disappointed. (LDS Professor Terryl L. Givens)

Despite the effort that went into the translation, Joseph Smith did not make the book the foundation of the church. (LDS Professor Richard L. Bushman)

The book under consideration bears no necessary relation to the Church of Jesus Christ of Latter-day Saints. They could exist quite independently of each other. (Book of Mormon Scholar J.N. Washburn)

Studies of Latter-day Saint sermons and curriculum from the earliest period of church history well into the 20th century demonstrate surprisingly little use of the Book of Mormon to establish doctrines or as a text from which to preach. Many Saints were converted by reading it, but, thereafter, they tended to overlook its specific content. Joseph seems somewhat detached from the book after its publication. (LDS Professor Daniel Peterson)

NO BOOKS OF MORMON PRINTED FOR 30 YEARS Fact, the Mormons did not print a single copy of the Book of Mormon, in America, between the years 1842 to 1869 (27 years). Finally, after 18 years, an independent publisher printed 4000 copies in New York.

Compare

2 Nephi 33:2 But behold, there are many that harden their hearts against the Holy Spirit, that it hath no place in them; wherefore, they cast many things away which are written and ESTEEM THEM AS THINGS OF NAUGHT.

[Brigham Young] took the Book of Mormon, and laid it down; and he took the Book of Doctrine and Covenants, and laid it down before him, and he said: “There is the written word of God to us, concerning the work of God from the beginning of the world, almost, to our day.” “And now,” said he, “when compared with the living oracles THOSE BOOKS ARE NOTHING TO ME...I would rather have the living oracles than all the writing in the books. (Conference Report, October 1897)

Those who treat the Book of Mormon as nothing, as naught, are those that "harden their hearts against the Holy Spirit, that it hath no place in them".

2 Nephi 18:20 To the law and to the testimony; and if they speak not according to this word, it is because there is no light in them.

Conclusion

I believe, if the Living Oracles are to be believed, that from the original condemnation til 1986 at least, the Church was led by those with darkened minds and the spirit had no place in them. They treated lightly the Book of Mormon. Their faith in it was tried and has been found wanting. Greater things, whether contained on the sealed portion or revelation through living oracles has been withheld at least from 1830 to 1986.

I quote the D&C and a Living Oracle, but I think it is obvious that the greater things will be revealed by the sealed portion once the Book of Mormon is not treated so lightly.

Lastly, imagine if the New York Times went back and edited their archives, adding to and taking from articles! Certainly, they have the right to do so since they are the ones who wrote them. Who would or could rely on anything googled on their site?
