The Sadducees did not believe that people would rise to life after death. So some of them came to Jesus
The Pharisees and Sadducees came to Jesus and tried to test him by asking for a sign from heaven.
Finally, the disciples understood that Jesus wasn't talking about the yeast used to make bread, but about the teaching of the Pharisees and Sadducees.
Jesus then warned them, “Watch out! Guard against the yeast of the Pharisees and Sadducees.”
The high priest and all the other Sadducees who were with him became jealous.
If we preach that Christ was raised from death, how can some of you say that the dead will not be raised to life?
