An exercise in missing the point
But the Sadducees do not couch their question so directly; rather, they try to ridicule the notion of resurrection with a worst-case scenario.

The Sadducees are basing their line of reasoning on Scripture, but they have not taken up a genuinely scriptural position; therefore45 they are in error. They did not really know the Scriptures. It is one thing to be able to quote passages that one thinks support one’s preconceived position and quite another to understand and follow the teaching of Scripture. To understand and to yield oneself to what Scripture says is quite different from quoting passages in the way the Sadducees were doing. And just as they do not really understand Scripture, so they do not know the power of God. The question of the resurrection from the dead is not one to be solved by citing a convenient passage from somewhere in the Bible; it demands that we recognize God’s power to do what he wills.
