What does Matthew 22:31 mean?
Jesus has forcefully corrected a collection of wrong assumptions held by the religious group known as the Sadducees. These errors were revealed by their question about a woman married to seven brothers, one by one, during her life on earth. In their minds, resurrection in an afterlife would imply she is now married to seven men (Matthew 22:15–28). Jesus has first corrected their mistaken belief that there is marriage after death (Matthew 22:29–30). His statement, in fact, proclaims two doctrines the Sadducees rejected: the existence of angels, and the reality of an afterlife.Here, Christ demonstrates that the very Scriptures the Sadducees claim to follow demonstrate the reality of an afterlife. In a brilliant maneuver, Jesus uses their exact strategy against them. In the following verse, He will ask a question, rooted in Scripture, which shows that some interpretation is impossible. In this case, the logic works, and the Sadducees will be stumped (Matthew 22:32–33).
Jesus often debated with religious leaders by asking if they have read something from Scripture. This time, though, He makes it personal. He asks if they have not read what God said to them. He will then quote to them from the Pentateuch, the only part of Scripture the Sadducees accept.
