Christ’s discourse in the synagogue concerning the bread of life was the turning point in the history of Judas. He heard the words, “Except ye eat the flesh of the Son of man, and drink His blood, ye have no life in you.” John 6:53. He saw that Christ was offering spiritual rather than worldly good. He regarded himself as farsighted, and thought he could see that Jesus would have no honor, and that He could bestow no high position upon His followers. He determined not to unite himself so closely to Christ but that he could draw away. He would watch. And he did watch. (DA 719.1) MC VC

From that time he expressed doubts that confused the disciples. He introduced controversies and misleading sentiments, repeating the arguments urged by the scribes and Pharisees against the claims of Christ. All the little and large troubles and crosses, the difficulties and the apparent hindrances to the advancement of the gospel, Judas interpreted as evidences against its truthfulness. He would introduce texts of Scripture that had no connection with the truths Christ was presenting. These texts, separated from their connection, perplexed the disciples, and increased the discouragement that was constantly pressing upon them. Yet all this was done by Judas in such a way as to make it appear that he was conscientious. And while the disciples were searching for evidence to confirm the words of the Great Teacher, Judas would lead them almost imperceptibly on another track. Thus in a very religious, and apparently wise, way he was presenting matters in a different light from that in which Jesus had given them, and attaching to His words a meaning that He had not conveyed. His suggestions were constantly exciting an ambitious desire for temporal preferment, and thus turning the disciples from the important things they should have considered. The dissension as to which of them should be greatest was generally excited by Judas. (DA 719.2) MC VC

When Jesus presented to the rich young ruler the condition of discipleship, Judas was displeased. He thought that a mistake had been made. If such men as this ruler could be connected with the believers, they would help sustain Christ’s cause. If Judas were only received as a counselor, he thought, he could suggest many plans for the advantage of the little church. His principles and methods would differ somewhat from Christ’s, but in these things he thought himself wiser than Christ. (DA 719.3) MC VC
