Do not divorce. Do not separate what God has joined together.
“It was also said, ‘Whoever divorces his wife must give her a bill of divorce.’ But I say to you, whoever divorces his wife causes her to commit adultery, and whoever marries a divorced woman commits adultery. Matthew 5:31-32
Some Pharisees approached him, and tested him, saying, “Is it lawful for a man to divorce his wife for any cause whatever?” He said in reply, “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.” They said to him, “Then why did Moses command that the man give the woman a bill of divorce and dismiss her?” He said to them, “Because of the hardness of your hearts Moses allowed you to divorce your wives, but from the beginning it was not so. I say to you, whoever divorces his wife and marries another commits adultery.” Matthew 19:3-9
But from the beginning of creation, ‘God made them male and female. 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.” In the house the disciples again questioned him about this. He said to them, “Whoever divorces his wife and marries another commits adultery against her; and if she divorces her husband and marries another, she commits adultery.” Mark 10:6-12
Marriage is not an agreement of convenience. It is a solemn vow before God. Divorce is rampant in society today. It is either because we do not understand marriage or because we do not respect God or both. His intention and command are clear. If there is a divorce then the parties should remain unmarried until the spouse dies.
