"Yet the members of the council were not all agreed. The Sanhedrin was not at this time a legal assembly. It existed only by tolerance. Some of its number questioned the wisdom of putting Christ to death. They feared that this would excite an insurrection among the people, causing the Romans to withhold further favors from the priesthood, and to take from them the power they still held. The Sadducees were united in their hatred of Christ, yet they were inclined to be cautious in their movements, fearing that the Romans would deprive them of their high standing. DA 539.1"
"Now the chief priests, and elders, and all the council, sought false witness against Jesus, to put him to death;"
Both passages refer to the council seeking to put Jesus to death.
In this council, assembled to plan the death of Christ, the Witness was present who heard the boastful words of Nebuchadnezzar, who witnessed the idolatrous feast of Belshazzar, who was present when Christ in Nazareth announced Himself the Anointed One. This Witness was now impressing the rulers with the work they were doing. Events in the life of Christ rose up before them with a distinctness that alarmed them. They remembered the scene in the temple, when Jesus, then a child of twelve, stood before the learned doctors of the law, asking them questions at which they wondered. The miracle just performed bore witness that Jesus was none other than the Son of God. In their true significance, the Old Testament Scriptures regarding Christ flashed before their minds. Perplexed and troubled, the rulers asked, “What do we?” There was a division in the council. Under the impression of the Holy Spirit, the priests and rulers could not banish the conviction that they were fighting against God. D…
"And it came to pass, that after three days they found him in the temple, sitting in the midst of the doctors, both hearing them, and asking them questions. And all that heard him were astonished at his understanding and answers."
EGW directly references the event described in Luke 2:46-47, where Jesus as a child astonished the doctors in the temple with his understanding and questions.
While the council was at the height of its perplexity, Caiaphas the high priest arose. Caiaphas was a proud and cruel man, overbearing and intolerant. Among his family connections were Sadducees, proud, bold, reckless, full of ambition and cruelty, which they hid under a cloak of pretended righteousness. Caiaphas had studied the prophecies, and although ignorant of their true meaning, he spoke with great authority and assurance: “Ye know nothing at all, nor consider that it is expedient for us, that one man should die for the people, and that the whole nation perish not.” Even if Jesus were innocent, urged the high priest, He must be put out of the way. He was troublesome, drawing the people to Himself, and lessening the authority of the rulers. He was only one; it was better that He should die than that the authority of the rulers should be weakened. If the people were to lose confidence in their rulers, the national power would be destroyed. Caiaphas urged that after this miracle the…
"And one of them, named Caiaphas, being the high priest that same year, said unto them, Ye know nothing at all, Nor consider that it is expedient for us, that one man should die for the people, and that the whole nation perish not."
The EGW passage directly quotes and elaborates on John 11:49-50, making it a clear explicit allusion.
"Even so ye also outwardly appear righteous unto men, but within ye are full of hypocrisy and iniquity."
The EGW passage describes Caiaphas and the Sadducees as hiding their cruelty under a cloak of righteousness, which aligns with the Matthew 23:28 description of outward righteousness masking inner hypocrisy. The connection is thematic and supports the characterization of Caiaphas.
