The Bible is the infallible interperter (Genesis 40:8, 2 Peter 1:20), as even Ellen herself taught unto her dying day.
To say otherwise is to misrepresent the Seventh-day Adventist position, and Ellen's position (as both are in print for all the world to see).
Isaiah 8:20, and so on.
"... The great error of the Romish church is found in the fact that the Bible is interpreted in the light of the opinions of the "fathers." These opinions are regarded as infallible, and the dignitaries of the church assume that it is their prerogative to make others believe as they do. Those who do not agree with them are pronounced heretics. But the word of God is not thus to be interpreted. It is to stand on its own eternal merits, to be read as the word of God, which declares his will to the people. {AU Gleaner, June 9, 1909 par. 4} ..." - Australasian Union Gleaner, June 9, 1909, par. 4
"... A familiar acquaintance with the Scriptures sharpens the discerning powers, and fortifies the soul against the attacks of Satan. The Bible is the sword of the Spirit, which will never fail to vanquish the adversary. It is the only true guide in all matters of faith and practice. ..." - The Advent Review and Sabbath Herald, January 4, 1881, par. 27
"... The Bible, and the Bible alone, is the rule of faith and practice. ..." - 1888 Materials, page 1532.2
"... The Bible is our Counselor, and is to be obeyed. ..." - 13MR (No. 1027), page 191.1
"... The truth of the Christian religion depends upon the divine authority of the word of God. ..." - Paulson Collection, page 110.7
"... We should not allow any argument of man's to turn us away from a thorough investigation of Bible truth. The opinions and customs of men are not to be received as of divine authority. God has revealed in his word what is the whole duty of man, and we are not to be swayed from the great standard of righteousness. He sent his only begotten Son to be our example, and bade us to hear and to follow him. We must not be influenced from the truth as it is in Jesus, because great and professedly good men urge their ideas above the plain statements of the word of God. {RH, July 17, 1888 par. 12} ..." - The Advent Review and Sabbath Herald, July 17, 1888, par. 12
"... My cry has been, Investigate the Scriptures for yourselves, and know for yourselves what saith the Lord. No man is to be authority for us. If he has received his light from the Bible, so may we also go to the same source for light and proof to substantiate the doctrines which we believe. The Scriptures teach that we should give a reason of the hope that is within us with meekness and fear. . . . {9MR 217.2} ..." - 9MR (No. 731), page 217.2
"... Truth, Bible truth, is to become the authority for the conscience and the love and life of the soul. {10MR 315.4} ..." - 10MR (No. 829), page 315.4
"... The Word of God is your counselor; the Word of God is your authority. Be very careful how you bring anything weaker to take its place...." - 14MR (1109), page 186.1
"... Christ rebuked these practices in His day. He taught that the word of God was to be understood by all. He pointed to the Scriptures as of unquestionable authority, and we should do the same. The Bible is to be presented as the word of the infinite God, as [40] the end of all controversy and the foundation of all faith. {COL 39.1} ..." - Christ Object Lessons, page 39.1
