What misled the Sadducees to believe that there is no such thing as the resurrection of the dead? Their own teachings and interpolations.

The Sadducees belonged to the higher echelon. They decided what to believe or what to do with those who disturb their minds and the Establishment. These religious and political leaders were submissive to the power of Rome, for their survival.

The Sadducees (high priests and aristocrats) saw Jesus as belonging to the Pharisaical movement who subscribe to the resurrection of the dead.

Jesus knows what he is teaching, for he comes from heaven. They should listen to him. He does not mislead. From Jesus, we get high-quality instructions on how we should relate to the almighty God. Since we belong to the Church we call the Catholic Church, we must listen to the interpretation of our Magisterium and its sound teachings.

Some Sadducees, who say there is no resurrection, came to Jesus and put this question to him, saying, “Teacher, Moses wrote for us, If someone’s brother dies, leaving a wife but no child, his brother must take the wife and raise up descendants for his brother. Now there were seven brothers. The first married a woman and died, leaving no descendants. So the second married her and died, leaving no descendants, and the third likewise. And the seven left no descendants. Last of all the woman also died. At the resurrection when they arise whose wife will she be? For all seven had been married to her.” Jesus said to them, “Are you not misled because you do not know the Scriptures or the power of God? When they rise from the dead, they neither marry nor are given in marriage, but they are like the angels in heaven. As for the dead being raised, have you not read in the Book of Moses, in the passage about the bush, how God told him, I am the God of Abraham, the God of Isaac, and the God of Jacob? He is not God of the dead but of the living. You are greatly misled.”
