Proof comes out at last.  EGW knew about their plans and closed door efforts.   Revisions without her say so, are treason, while revisions, with her approval and personal hand in the work, are needed upgrades.  Earlier books sometimes informed members, but told too much to the general public, at that time, which they could profit by later, from earlier books, after spiritual growth. 

Example   DA >  Christ our Saviour - for children in their language levels, 1SG and steampress editions > GC 88 & GC 11 for outreach and potential baptismal candidates, 1SG & steampress editions and now fully released manuscripts, for full members having grown and accepted the doctrine of SOP. 

Lucifer decided to improve God's works, as he felt he knew best, so did Judas, and The Man of Sin the son of perdition, same principles at work.  What Lucifer, Judas, Man of sin, attempted was not authorized upgrades / revisions for readers needs, it was replace, rewrite, destroy originals, it was treason.

the minutes of the 1919 Bible Conferences:c

A. G. Daniells: Well, now, which statement shall we take, the original or the revised?

B. L. House: My real difficulty is just here: Sister White did not write either the old edition or the revised, as I understand it.

A. G. Daniells: What do you mean by saying that she did not write either edition?

B. L. House: As I understand it, Elder J. N. Anderson prepared those historical quotations for the old edition, and Brother Robinson and Brother Crisler, Professor Prescott and others furnished the quotations for the new edition. Did she write the historical quotations in there?

A. G. Daniells: No.

http://sdanet.org/atissue/books/1919bc/0801-1919bc.htm

And here is again Prescott speaking:

W. W. Prescott: You are touching exactly the experience through which I went, personally, because you all know that I contributed something toward the revision of "Great Controversy." I furnished considerable material bearing upon that question.

A. G. Daniells: By request. c

W. W. Prescott: Yes, I was asked to do it, and at first I said, "No, I will not do it. I know what it means." But I was urged into it. When I had gone over it with W. C. White, then I said, "Here is my difficulty. I have gone over this and suggested changes that ought to be made in order to correct statements. These changes have been accepted. My personal difficulty will be to retain faith on those things that I can not deal with on that basis." But I did not throw up the spirit of prophecy, and have not yet; but I have had to adjust my view of things. I will say to you, as a matter of fact, that the relation of those writings to this movement and to our work, is clearer and more consistent in my mind than it was then. But still you know what I am charged with. I have gone through the personal experience myself over that very thing that you speak of. If we correct it here and correct it there, how are we going to stand with it in the other places?

And now, guess what was one of the major sources of inspiration for the latter editions of GC?

W. W. Prescott: I do not want to charge anybody. But I do think great mistakes were made in that way. That is why I have made a distinction as I have. When I talked with W. C. White about it (and I do not know that he is an infallible authority), he told me frankly that when they got out "Great Controversy," if they did not find in her writings anything on certain chapters to make the historical connections, they took other books, like "Daniel and the Revelation," and used portions of them; and sometimes her secretaries, and sometimes she herself, would prepare a chapter that would fill the gap.

Do not state anything I have told you personally in regard to the matter of change in books.  {Lt104-1899 (August 1, 1899) par. 8}

R. & H., 5, p. 110:--   That which I have written is what the Lord has bidden me write.  I have NOT been instructed to change that which I have sent out.  (1905)

Testimony 13, pp. 12-14:--  That night I dreamed I was in Battle Creek looking out from the side glass at the door, and saw a company marching up to the house, two and two.  They looked stern and determined.  I knew them well and turned to open the parlor door to receive them, but thought I would look again.  The scene was changed.  The appearance now presented was like a Catholic procession.  One of the company bore in his hand a cross.  Another had a reed.  And as they neared the house, the one carrying a reed made a circle around the house, saying three times, This house is proscribed.  The goods * must be confiscated.  they have spoken against our holy order.  Terror seized me, and I ran through the house, out of the north door, and found myself in the midst of a company some of whom I knew, but I dared not speak a word with them for fear of being betrayed.  I tried to seek a retired spot where I might weep and pray without meeting eager, inquisitive eyes everywhere I turned.  I repeated frequently, If I could only understand this!  If they will tell me what I have said, or what I have done!  I wept and prayed much as I saw our goods* being confiscated.  I tried to read sympathy or pity for me in the looks of those around me, and marked several countenances of those whom I thought would speak with me, and comfort me, if they did not fear that they would be observed by others.  I made one attempt to escape from the crowd, but I saw that I was watched, and I concealed my intentions.  I commenced weeping aloud, saying, If they would only tell me what I have done, or what I have said!  My husband, who was sleeping in a bed in the same room, heard me weeping aloud, and awoke me.  I found my pillow wet with tears, and a sad depression of spirits upon me.  (1867. NOTE:--* = the good confiscated would be the writings of Br. and Sr. White.)

R&H, October 16, 1883 par. 17   I will not shun to declare the whole counsel of God. Unpleasant as it may be, I must warn, reprove, rebuke, as God bids me, whether the carnal heart will accept or reject the words of warning. For forty years, Satan has made the most determined efforts to cut off this testimony from the church; but it has continued from year to year to warn the erring, to unmask the deceiver, to encourage the desponding. My trust is in God. I have learned not to be surprised at opposition in any form or from almost any source. I expect to be betrayed, as was my Master, by professed friends. 

     The above statement from Sr. Whites pen, was issued approximately six weeks, prior to the 1883 General Conference Session, passing the following resolution, to set up a committee of five, to change the Testimonies of the Holy Spirit.

Ellen G. White Messenger to the Remnant; By A.L. White, p. 65-- {ND UrS, QUAN 2.8} Review and Herald, Nov. 27, 1883]   32. Whereas, Some of the bound volumes of the 'Testimonies to the Church' are out of print so that full sets cannot be obtained at the office; and  "Whereas, there is a constant and urgent call for the re-printing of these volumes; therefore, -  "Resolved, that we recommend their re-publication in such a form as to make four volumes of seven or eight hundred pages each. 

"33. Whereas, many of these testimonies were written under the most unfavorable circumstances, the writer being too heavily pressed with anxiety and labor to devote critical thought to the grammatical perfection of the writings, and they were printed in such haste as to allow these imperfections to pass uncorrected; and. -  "Whereas, we believe the light given by God to His servants is by the enlightenment of the mind, thus imparting the thoughts, and not (except in rare cases) the very words in which the ideas should be expressed; therefore, - 

"34.  Resolved that in the re-publication of these volumes, such verbal changes be made as to remove the above-named imperfections, as far as possible, without in any measure changing the thought."

NOTE: -- The committee of five to change the Testimonies of the Holy Spirit was made up of the following individuals:- G.I. Butler chairman; S.N. Haskell; Uriah Smith; J.H. Waggoner; W.C. White.  the fact that the brethren put Uriah Smith on this committee, when he had been publicly rebuked in the preceding year (1882), for rejecting the Testimonies, shows us how much faith the leaders of the SDA church had in the testimonies of the Holy Spirit!  We can now see why in the previous pages, the rebukes personally addressed to Uriah Smith, have been removed from Testimonies to the Church, after the 1883 G.C. resolution was passed.  The committee of five, removed these rebukes from the Testimonies as they were reprinted!

     This 1883 G.C. resolution uses the excuse that the Testimonies had to be changed because of the grammatical imperfections contain in them.  We shall prove that this was a false statement, to give the brethren an excuse to change the Testimonies.  The following quotes will demonstrate that this charge of grammatical imperfections is a lie!

Ministry Magazine, April, 1994, pp. 10,12:--  Mrs. Whites remarks concerning the revision were not recorded, but whatever she said, the General Conference session did NOT choose to cite her as authority for their action.   Relatively few changes involved actual grammatical errors.  The vast majority of wording changes did NOT involve grammatical errors at all. (By Ronald Graybill)

SR. WHITE WAS NOT AUTHORIZED TO CHANGE  HER WRITINGS:--

Original Testimony 26, p. 4:--  Here is a work that has been subjected to the most rigid criticisms, and the most violent persecutions for the long period of twenty years, and YET REMAINS UNCHANGED.  Had this work originated in the mind of an unsophisticated woman, it would have been forced out of its course long since and brought to confusion and to naught. (1876 Elder James White)

They come to me, those that are copying my writings, and say, Now here is the better revised words, and I think I will put that in. Dont you change one word, not a word. The revised edition we do not need at all. We have got the word that Christ has spoken Himself and given us. And dont you in my writings change a word for any revised edition. There will be revised editions, plenty of them, just before the close of this earths history, and I want all my workers to understand, and I have got quite a number of them. I want them to understand that they are never to take the revised word, and put it in the place of the plain, simple words just as they are. They think they are improving them, but how do they know but that they may switch off on an idea, and give it less importance than Christ means them to have. {Ms188-1907} 

Are we right to believe that everything which was published during Ellen Whites lifetime under her signature was genuine, having her approval and, even more important, bearing Gods mark of authority. Unfortunately that was not the case, as Ellen herself plainly stated:
There is another fact that should be stated here. I am not responsible for all that has been printed as coming from me. About the time that my earliest visions were first published, several articles did appear purporting to have been written by me, and to relate what the Lord had shown me, but sanctioning doctrines which I did not believe. [...]  {1SM 60.4}
For the beginning I am going to bring to notice just one of the very many evidences, quoting from we usually take as an Ellen White book:
A meat diet is not the most wholesome of diets, and yet I would not take the position that meat should be discarded by every one. Those who have feeble digestive organs can often use meat, when they cannot eat vegetables, fruit, or porridge. If we would preserve the best health, we should avoid eating vegetables and fruit at the same meal. If the stomach is feeble, there will be distress, the brain will be confused, and unable to put forth mental effort. Have fruit at one meal and vegetables at the next. . . .  {CD 394.3} 
Here is a portion of what was first published May 31, 1894 under the signature of Mrs. E. G. White, as an article of Youths Instructor. Parts of the article were included in another compilation on health published during her lifetime, entitled Healthful Living (1897, 1898). Later, this quote, as shown above, became part of the compilation Counsels to Diet and Foods, published in 1938. Since all of them were published under the name of Ellen White, we should throw our full confidence in their words, right? Well not really! Look at the kind of confidence Ellen White herself had when she read them:
Sister Davis has just called my attention to an article printed in the Youth's Instructor of May 31, 1894. The question asked is, Did I design to have this sentence just as it appeared in the Instructor? I am surprised to see it just as it appears--"A meat diet is not the most wholesome of diets, and yet I would take the position that meat should not be discarded by everyone." I cannot explain why this appears just as it does.  {SpM 81.1} 
The same is to be found in {1888 1376.3} and {14MR 324.3}. Published years later, in 1985, 1987, respectively 1990, long after the death of Ellen White and, of course, beyond her supervision! But also, as we are can see (if we want to see), beyond the supervision of those who were in charge of the publishing work while she was living and who were at odds with the health reform. And, another big difference: we can read these remarks made by Ellen White regarding of what sister Davis found in Youths Instructor in the context of the whole manuscript, as the manuscript was published entirely in all these three collections of testimonies that I mentioned. This is not the case for the article of this periodical because, before being published, it was subject to the work of the editors and, of course, it is not the case for the compilations on health which quote from this article. Though Counsels to Diet and Foods is probably a book more widely translated and distributed than either of Spalding and Magan Collection, or 1888 Materials.
So, is it possible that there are better known quotes falsely attributed to EGW, which are used as evidence for certain teachings and interpretations advocated by some, while other authentic EGW quotes which contradict them are neglected because they seem more obscure?

Look up the part leaders took in rejecting the Holy Ghost and His message in 1888.  Read "Return of the Latter Rain" and compare history from the bibliographies(chapter end notes), and you will see many of the same names that rejected the 1888 message and the messengers, A.T Jones, E.J Waggoner, Ellen G White; were also rejecting the God Who sent the messengers and message.  Thus the wandering in the wilderness of Earth has continued for 100 + years.  It is no surprise these men would also change the signposts and boundary markers.  No wonder you like the 1858 edition.
