"But none need be deceived concerning them. It may be readily seen whose children they are, whose example they follow, and whose work they do. “Ye shall know them by their fruits.” Matthew 7:16 . Their course resembles that of Satan, the envenomed slanderer, “the accuser of our brethren.” Revelation 12:10 . GC 519.3 The great deceiver has many agents ready to present any and every kind of error to ensnare souls—heresies prepared to suit the varied tastes and capacities of those whom he would ruin. It is his plan to bring into the church insincere, unregenerate elements that will encourage doubt and unbelief, and hinder all who desire to see the work of God advance and to advance with it. Many who have no real faith in God or in His word assent to some principles of truth and pass as Christians, and thus they are enabled to introduce their errors as Scriptural doctrines. GC 520.1"
"Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?"
Ellen White directly references Matthew 7:16 in this passage.
"And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night."
Ellen White directly references Revelation 12:10 in this passage.
"The position that it is of no consequence what men believe is one of Satan's most successful deceptions. He knows that the truth, received in the love of it, sanctifies the soul of the receiver; therefore he is constantly seeking to substitute false theories, fables, another gospel. From the beginning the servants of God have contended against false teachers, not merely as vicious men, but as inculcators of falsehoods that were fatal to the soul. Elijah, Jeremiah, Paul, firmly and fearlessly opposed those who were turning men from the word of God. That liberality which regards a correct religious faith as unimportant found no favor with these holy defenders of the truth. GC 520.2"
"I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel: Which is not another; but there be some that trouble you, and would pervert the gospel of Christ. But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed. As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed."
Both passages address the danger of false gospels and the importance of adhering to the true gospel. Galatians 1:6-9 strongly condemns those who preach a different gospel, while EGW emphasizes that Satan seeks to substitute false theories for the truth.
"The vague and fanciful interpretations of Scripture, and the many conflicting theories concerning religious faith, that are found in the Christian world are the work of our great adversary to confuse minds so that they shall not discern the truth. And the discord and division which exist among the churches of Christendom are in a great measure due to the prevailing custom of wresting the Scriptures to support a favorite theory. Instead of carefully studying God's word with humility of heart to obtain a knowledge of His will, many seek only to discover something odd or original. GC 520.3"
"As also in all his epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction."
Both passages directly address the issue of twisting or wresting Scripture. 2 Peter 3:16 warns against the unlearned and unstable wresting the scriptures to their own destruction. EGW echoes this concern, stating that the discord among churches is due to wresting the Scriptures to support favorite theories.
