Genesis 2: 18-24
Then the Lord God said, “It’s not good that the human is alone. I will make him a helper that is perfect for him.” So the Lord God formed from the fertile land all the wild animals and all the birds in the sky and brought them to the human to see what he would name them. The human gave each living being its name. The human named all the livestock, all the birds in the sky, and all the wild animals. But a helper perfect for him was nowhere to be found.
So the Lord God put the human into a deep and heavy sleep, and took one of his ribs and closed up the flesh over it. With the rib taken from the human, the Lord God fashioned a woman and brought her to the human being. The human said,
“This one finally is bone from my bones
and flesh from my flesh.
She will be called a woman
because from a man she was taken.”
This is the reason that a man leaves his father and mother and embraces his wife, and they become one flesh.
Mark 10: 2-16
Some Pharisees came and, trying to test him, they asked, “Does the Law allow a man to divorce his wife?”
Jesus answered, “What did Moses command you?”
They said, “Moses allowed a man to write a divorce certificate and to divorce his wife.”
Jesus said to them, “He wrote this commandment for you because of your unyielding hearts. At the beginning of creation, God made them male and female. Because of this, a man should leave his father and mother and be joined together with his wife, and the two will be one flesh. So they are no longer two but one flesh. Therefore, humans must not pull apart what God has put together.”
Inside the house, the disciples asked him again about this. He said to them, “Whoever divorces his wife and marries another commits adultery against her; and if a wife divorces her husband and marries another, she commits adultery.”
People were bringing children to Jesus so that he would bless them. But the disciples scolded them. When Jesus saw this, he grew angry and said to them, “Allow the children to come to me. Don’t forbid them, because God’s kingdom belongs to people like these children. I assure you that whoever doesn’t welcome God’s kingdom like a child will never enter it.” Then he hugged the children and blessed them.
