Here is a better explanation...
"...I find this rather amazing that Ellen White specifically told the church not to use her as their source of truth, but learn from the truths from the bible. Amen.
Ellen White herself said: "Let all prove their positions from the Scriptures and substantiate every point they claim from the revealed Word of God."397 To the delegates of the General Conference in 1901, she said, "Lay Sister White right to one side: lay her to one side. Don't you never [sic] quote my words again as long as you live, until you can obey the Bible. When you take the Bible and make that your food, and your meat, and your drink, and you make that the elements of your character, when you can do that you will know better how to receive some counsel from God. But here is the Word, the precious Word, exalted before you today. And don't you give a rap any more what 'Sister White Said' [sic]—'Sister White said this,' and 'Sister White said that,' and 'Sister White said the other thing'. But say, 'Thus saith the Lord God of Israel.'398 ..."
"...The final court of appeal must always be the Bible.
This was the strong conviction of her husband James White who wrote: "There is a class of persons who are determined to have it that the Review and its conductors make the views of Mrs. White a test of doctrine and Christian fellowship. . . . What has the Review to do with Mrs. White's views? The sentiments published in its columns are all drawn form the Holy Scriptures. No writer of the Review has ever referred to them as authority on any point. . . . It's motto has been, 'The Bible, and the Bible alone, the only rule of faith and duty.'. . .
"Every Christian is therefore duty bound to take the Bible as the perfect rule of faith and duty. He should pray fervently to be aided by the Holy Spirit in searching the Scriptures for the whole truth, and for his whole duty. He is not at liberty to turn from them to learn his duty through any of the gifts. We say that the very moment he does, he places the gifts in a wrong place, and takes an extremely dangerous position."395
He could see that, very early in Adventism, some were inclined to give her writings an authority over and above the Scriptural authority for the work of a prophet. "They conclude that if it be true that God is reviving some of the gifts, 'for the comfort of his people, and correct those who err from Bible truth.' That all errors would at once be corrected by these gifts, and the church be saved the trouble of searching the Word for truth to expose error. . . . They would put the gifts where they do not belong. . . . The revival of any, or all of the gifts, will never supersede the necessity of searching the Word to learn the truth."396 ...."
"...the Bible is its own interpreter and every Christian is free to study the Bible (guided by the Holy Spirit) to find truth for themselves. The following points support James White in his stand:
1. Jesus left a promise to His Church. "All this I have spoken while still with you. But the Counsellor, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you." ( John 14:25-26)
2. Recognising this point and practicing it is part of being Protestant. The Catholic Church tried to impose upon Christians the role of the pope as the infallible interpreter of Scripture. This concept was rejected by Protestants, because it violated the principle of sola Scriptures. Besides, once you have any external authority telling you what the Bible means, you make that authority more powerful than the Bible itself.
3.The Bible is a completed book. Hebrews 1:1 gives the reason for this, "In the past God spoke to our forefathers through the prophets at many times and in various ways, but in these last days he has spoken to us by his Son. . . . " The generation of Jesus' day were taught by Christ and individuals wrote down what they had learned. Jesus was the fullest, most complete revelation of God. Nothing that comes after Him will ever add to or eclipse the revelation of God in Him. All that comes after will be but a reflection of the light that shone through Him. Therefore the work of prophets is to call people back to study and obey that final, complete, revelation in Jesus. The work of prophets is to point out duties already revealed and neglected...."excerpted from MORE THAN A PROPHET ... by Graeme Bradford.
