About this time, fanaticism began to appear. Some who had professed to be zealous believers in the message rejected the word of God as the one infallible guide and, claiming to be led by the Spirit, gave themselves up to the control of their own feelings, impressions, and imaginations. There were some who manifested a blind and bigoted zeal, denouncing all who would not sanction their course. Their fanatical ideas and exercises met with no sympathy from the great body of Adventists; yet they served to bring reproach upon the cause of truth. (GC 395.1) MC VC

Satan was seeking by this means to oppose and destroy the work of God. The people had been greatly stirred by the advent movement, thousands of sinners had been converted, and faithful men were giving themselves to the work of proclaiming the truth, even in the tarrying time. The prince of evil was losing his subjects; and in order to bring reproach upon the cause of God, he sought to deceive some who professed the faith and to drive them to extremes. Then his agents stood ready to seize upon every error, every failure, every unbecoming act, and hold it up before the people in the most exaggerated light, to render Adventists and their faith odious. Thus the greater the number whom he could crowd in to make a profession of faith in the second advent while his power controlled their hearts, the greater advantage would he gain by calling attention to them as representatives of the whole body of believers. (GC 395.2) MC VC

Satan is “the accuser of the brethren,” and it is his spirit that inspires men to watch for the errors and defects of the Lord’s people, and to hold them up to notice, while their good deeds are passed by without a mention. He is always active when God is at work for the salvation of souls. When the sons of God come to present themselves before the Lord, Satan comes also among them. In every revival he is ready to bring in those who are unsanctified in heart and unbalanced in mind. When these have accepted some points of truth, and gained a place with believers, he works through them to introduce theories that will deceive the unwary. No man is proved to be a true Christian because he is found in company with the children of God, even in the house of worship and around the table of the Lord. Satan is frequently there upon the most solemn occasions in the form of those whom he can use as his agents. (GC 395.3) MC VC
