Last Sunday, I taught from Matthew 19:1-12. In this passage, the Pharisees raise a question about divorce. Jesus answers by quoting two passages from Genesis (1:27 and 2:24). Then Jesus adds that the two people (husband and wife) become one flesh and should not be separated.
Scripture only describes three entities as multiple and yet one – God, husband/wife, and the church. Both the husband/wife and church relationship demonstrate the image of God. The question of divorce is related to our understanding of the image of God. (By the way, this is true of church “splits” or separation – they are extremely damaging.)
Also, Jesus points out that the Pharisees are misusing Scripture. The Pharisees (and others) added human traditions to Scripture so that they were able to keep the rules. Eventually, they could not differentiate between their own man-made rules and God’s law. If they had stuck with God’s law, they would have discovered that it was impossible for them to keep.
