"It will be found that those who bear false messages will not have a high sense of honor and integrity. They will deceive the people, and mix up with their error the Testimonies of Sister White, and use her name to give influence to their work. They make such selections from the Testimonies as they think they can twist to support their positions, and place them in a setting of falsehood, so that their error may have weight and be accepted by the people. They misinterpret and misapply that which God has given to the church to warn, counsel, reprove, comfort, and encourage those who shall make up the remnant people of God. Those who receive the Testimonies as they message of God wil be helped and blessed thereby; but those who take them in parts, simply to support some theory or idea of their own, to vindicate themselves in a course of error, will not be blessed and benefited by what they teach." E.G. White, Testimonies to Ministers and Gospel Workers, 42.
Many Adventists think that the above statement applies only to offshoot who leave the church. I would remind you that Ellen White says that it is also erring leaders who have often misapplied and misinterpreted Scripture and the Testimonies. Please note:
"The angel of the Lord by night opened the prison doors, and brought them forth, and said, ' Go, stand and speak in the temple to the people all the words of this life.' We see here that the men in authority are not always to be obeyed, even though they may profess to be teachers of Bible doctrines. There are many today who feel indignant and aggrieved that any voice should be raised presenting ideas that differ from their own in regard to points of religious belief. Have they not long advocated their ideas as truth? So the priests and rabbis reasoned in apostolic days. What mean these men who are unlearned, some of them mere fishermen, who are presenting ideas contrary to the doctrines which the learned priests and rulers are teaching the people? They have no right to meddle with the fundamental principles of our faith. But we see that the God of heaven sometimes commissions men to teach that which is regarded as contrary to the established doctrines. Because those who were ONCE THE DEPOSITARIES OF TRUTH BECAME UNFAITHFUL TO THEIR SACRED TRUST, THE LORD CHOSE OTHERS who would receive the bright beams of the Sun of Righteousness, and would advocate truths that were not in accodance with the ideass of the religious leaders. And then these leaders, in the blindness of ther minds, give full sway to what is supposed to be righteous indignation against the ones who have set aside CHERISHED FABLES. They act lie men that have LOST THEIR REASON. They do not consider the possibility that they themselves have not rightly understood the word. They will not open their eyes to discern the fact that they have MISINTERPRETED AND MISAPPLIED the Scriptures, and have built up false theories, calling them fundamental doctrines of the faith." The Ellen G. White 1888 Materials, p. 1545.
"The Jews perished AS A NATION [CORPORATELY=CORPORATE RESPONSIBILITY ] because they were drawn from the truth of the Bible by their rulers, priests, and elders. Had they heeded the lessons of Jesus, and searched the Scriptures for themselves, they would not have perished." E.G. White, Testimonies to Ministers, 109.
"Satan's snares are laid for us as verily as they were laid for the children of Israel just prior to their entrance into the land of Canaan. We are repeating the history of that people." Testimonies, vol. 5, 146.
