Theophylact of Ohrid

A certain heretical sect of the Jews called Sadducees denied the resurrection, and said that there was neither angel nor spirit. These then coming to Jesus, craftily proposed to Him a certain tale, in order to show that no resurrection should take place, or had taken place; and therefore there is added, And they asked him, saying, Master. And in this tale they lay down that seven men had married one woman, in order to make men draw back from belief in the resurrection.

Bede

The Sadducees, who say there is no resurrection, came to him. There were two sects among the Jews, one of the Pharisees and the other of the Sadducees. The Pharisees, who preferred justice of traditions and observances which they called "deuterosis," were commonly known as separated from the people. But the Sadducees, whose name means "just," also claimed what they were not. The former believed in the resurrection of both body and soul, and admitted angels and spirits; the latter, following the Acts of the Apostles, denied everything.

Glossa Ordinaria

After that our Lord has prudently escaped the crafty temptation of the Pharisees, it is shown how He also confounds the Sadducees, who tempt Him; wherefore it is said: Then come unto him the Sadducees, which say there is no resurrection.
