Jesus said, “Have you not read that from the beginning the Creator ‘made them male and female’ and said, ‘For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh’? So they are no longer two, but one flesh. Therefore, what God has joined together, no human being must separate.” – [Matthew 19:4-6]
Surely, the ‘one flesh’ union that God spoke of from the beginning was never intended for separation. This was Jesus’ response to divorce, but it also poses an insight for married couples. Do we live the ‘one flesh’ union? If we were two and now one, do we act like so? Do we keep things from our other half?
Of course, there are other ways to deny the ‘one flesh’ union. Lusting for another is one way, but also clinging to one’s parents or friends at the same level as one’s spouse does as well. Sure, we are to honor our parents, but we are to leave them to be joined to our spouse.
People seem to enjoy poking holes in theological ideas like the 'one flesh' union. The questions about an abusive spouse, annulments, and others come up. As for annulments, Jesus said, “what God has joined together, no human being must separate.” Annulments are an investigation of whether God created a union from two people. As for an abusive spouse, if your left hand uncontrollably hurt you, would you not look for a way to prevent it from hurting you? Remember that separation is valid and so may be legal divorce, but attempting remarriage while already in a union joined by God is where sin occurs.
