When it comes to the word of God the message being spoken is more important than who brought it. If she quoted from other sources on purpose to prove a point then I see nothing wrong with that. The message still got out to those who had not heard it before, she acknowledged that some of what was written was taken from other works but it is not the authority of the writer she was quoting but the summation and explanation given for a certain subject, so there is no need for a citation. What matters is that most of what she wrote IS true such as the Sabbath day worship, the Mark of the Beast being the Abominable Sunday Law, and the Majority/Much of her prophesy on the End.
Problem is in all her writings which are many she passed the words of others off as hers. She did not give proper quotation of the era which is the same as today. That in short is stealing.
Ellen White (1827-1915): “She then said, ‘The inhabitants [of Saturn] are a tall, majestic people, so unlike the inhabitants of earth. Sin has never entered here’” (From the letter of Mrs. M. C. Truesdail, January 27, 1891).

Ellen White (1827-1915): “The Lord has given me a view of other worlds….Then I saw two trees, one looked much like the tree of life in the city. The fruit of both looked beautiful, but of one they could not eat….Then my attending angel said to me, “None in this place have tasted of the forbidden tree….” (EW, pp. 39-40, 1882).
“…when Jesus brought along the crowns and with His own right hand placed them on our heads” (Word to The Little Flock, p. 15, 1847).
“Then I saw very great number of angels bring from the city glorious crowns- a crown for every saint, with his name written thereon. As Jesus called for the crowns, the angels presented it to Him, and with His own hand, the lovely Jesus placed the crowns on the heads of the saints” (Early Writings, p. 288, 1882).
Thirty five years later:
“I have never seen any persons crowned in the kingdom of God, only on conditions that if they were faithful they would receive the crown of immortal life in the kingdom of glory” (8 MR, p. 239, 1990).
For a time after the disappointment in 1844, I did hold, in common with the advent body, that the door of mercy was then forever closed to the world.--Ellen G. White Ms. 4, 1883; Selected Messages, book 1, p. 63.
At the time I had the vision of the midnight cry I had given it up in the past and thought it future, as also most of the band had.--Ellen G. White Letter 3, 1847, written July 13, 1847 to Joseph Bates.
When she received her first vision, Dec. 1844, she and all the band in Portland, Maine, (where her parents then resided) had given up the midnight-cry, and shut door, as being in the past. It was then that the Lord shew her in vision, the error into which she and the band in Portland had fallen. She then related her vision to the band, and about sixty confessed their error, and acknowledged their 7th month experience to be the work of God.--James White,
A Word to the Little Flock, p. 22.

"
The "7th month experience," or "midnight cry," was the proclamation that Christ would return on the 10th day of the 7th Jewish month, which in 1844 fell on October 22. In her first vision Ellen Harmon was shown that the seventh month movement was "the work of God." In other words, the Millerite calculations based on Daniel 8:14 were not to be discarded as an unfortunate blunder.
This vision substantiated the validity of the October 22 date. However, since Christ had not returned on that date, the prophecy of Daniel 8:14 must have been fulfilled by some other event. James White indicates that, on the basis of what she was shown in her first vision, Ellen Harmon reverted to her earlier view that the door was shut on October 22. She apparently now believed that the door of mercy was closed."

In 1891 Uriah Smith wrote:
In the midst of this evolution of new views, a few weeks after the passing of the time, and while many were making shipwreck of faith, Sister White had her first vision. In it she was shown that "the midnight cry," which they had just passed through, was a great light set up behind them, and was not to be rejected; that if kept in view, it would shed light on the pathway clear through to the end; but if rashly denied, darkness and ruin to such souls would follow. Now says the objector, "The visions taught the shut door, because the shut-door view was connected with that of the midnight cry; and the vision taught that the midnight cry was not to be given up." The conclusion does not follow. It is a false charge. The vision said nothing about the shut door. But the midnight cry was a vital pillar of truth, and was not to be surrendered, though some errors had been connected with it. To give up the midnight cry was to give up the whole work, and make utter shipwreck of faith. And any candid reader can judge whether it were better to give up that truth on account of an error which men had attached to it, and so wholly apostatize, rather than hold fast to the truth, and wait patiently till the Lord should remove the error which men had connected with it. Everyone will say the latter. And this they did; and the explanation and correction came in due time.--Review and Herald, January 6, 1891, p. 8.
[p. 7]
Ellen White's explanation of the true meaning of her first vision ("the true position") is as follows:
For a time after the disappointment in 1844, I did hold, in common with the advent body, that the door of mercy was then forever closed to the world. This position was taken before my first vision was given me. It was the light given me of God that corrected our error, and enabled us to see the true position.
I am still a believer in the shut-door theory, but not in the sense in which we at first employed the term or in which it is employed by my opponents.
There was a shut door in Noah's day. There was at that time a withdrawal of the Spirit of God from the sinful race that perished in the waters of the Flood. God Himself gave the shut-door message to Noah:
"My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years" (Gen. 6:3).
There was a shut door in the days of Abraham. Mercy ceased to plead with the inhabitants of Sodom, and all but Lot, with his wife and two daughters, were consumed by the fire sent down from heaven.
There was a shut door in Christ's day. The Son of God declared to the unbelieving Jews of that generation, "Your house is left unto you desolate" (Matt. 23:38).
Looking down the stream of time to the last days, the same infinite power proclaimed through John:
"These things saith he that is holy, he that is true, he that hath the key of David, he that openeth, and no man shutteth; and shutteth, and no man openeth" (Rev. 3:7).
I was shown in vision, and I still believe, that there was a shut door in 1844. All who saw the light of the first and second angels' messages and rejected that light, were left in darkness. And those who accepted it and received the Holy Spirit which attended the proclamation of the message from heaven, and who afterward renounced their faith and pronounced their experience a delusion, thereby rejected the Spirit of God, and it no longer pleaded with them.
Those who did not see the light, had not the guilt of its rejection. It was only the class who had despised the light from heaven that the Spirit of God could not reach. And this class included, as I have stated, both those who refused to accept the message when it was presented to them, and also those who, having received it, afterward renounced their faith. These might have a form of godliness, and profess to be followers of Christ; but having no living connection with God, they would be taken captive by the delusions of Satan. These two classes are brought to view in the vision--those who declared the light which they had followed a delusion, and the wicked of the world who, having rejected the light, had been rejected of God. No reference is made to those who had not seen the light, and therefore were not guilty of its rejection.--Ms. 4, 1883; Selected Messages, book 1, pp. 63-64.

The Scapegoat (Christ/Satan)
“It was seen, also, that while the sin-offering pointed to Christ as a sacrifice, and the high priest represented Christ as a mediator, the scape-goat typified Satan, the author of sin, upon whom the sins of the truly penitent will finally be placed. When the high priest, by virtue of the blood of the sin-offering, removed the sins from the sanctuary, he placed them upon the scape-goat. When Christ, by virtue of his own blood, removes the sins of his people from the heavenly sanctuary at the close of his ministration, he will place them upon Satan” (4SP, pp. 266, 267, 1884).
“Satan not only bore the weight and punishment of his sins, but the sins of all the redeemed host had been placed upon him…” (1SG, p. 217, 1858; EW, pp. 294, 295, 1882).
Note: She believed the scapegoat to be Satan as taught by Crosier in 1847. In 1858 Ellen White said that Satan will have to bear the sins of the redeemed as well as his own and in 1884 she identified the scapegoat as Satan.
Fifty years later:
“Some apply the solemn type, the scape goat, to Satan. This is not correct. He cannot bear his own sins. At the choosing of Barabbas, Pilate washed his hands. He cannot be represented as the scape goat…Christ was the scape goat, which the type represents. He alone can be represented by the goat borne into the wilderness. He alone, over whom death had no power, was able to bear our sins” (The Scapegoat in the Writings of Ellen G. White, Alberto R. Timm, Ellen White Estate, [Accessed from internet on Oct 26, 2013]; Manuscript 112, 1897).
Note: I presume that this quotation was deliberately suppressed from being used as it contradicts and destroys the sanctuary doctrine, and sensing this serious threat to our church, Ellen White refrained from further use of this statement.
