A.T. Robertson Commentary Mark 12:18

"And there come unto him Sadducees, who say that there is no resurrection; and they asked him, saying," — Mark 12:18 (ASV)

There come unto him Sadducees (ερχοντα Σαδδουκαιο προς αυτον). Dramatic present. The Pharisees and Herodians had had their turn after the formal committee of the Sanhedrin had been so completely routed. It was inevitable that they should feel called upon to show their intellectual superiority to these raw Pharisaic and Herodian theologians. See on Mt 22:23-33 for discussion of details. It was a good time to air their disbelief in the resurrection at the expense of the Pharisees and to score against Jesus where the Sanhedrin and then the Pharisees and Herodians had failed so ignominiously.
