The birth of Jesus Christ occurred in this way. When his mother Mary was engaged to Joseph, but before they came to live together, she was found to be with child through the Holy Spirit.
But from the very beginning of creation, ‘God made them male and female.’ ‘That is why a man leaves his father and mother and is joined to his wife, and the two become one flesh.’ And so they are no longer two but one flesh. Therefore, what God has joined together, let no one separate.
You shall not kill. You shall not commit adultery. You shall not steal. You shall not bear false witness. Honor your father and your mother. Love your neighbor as yourself.
Then the angel said to her, “Do not be afraid, Mary, for you have found favor with God. Behold, you will conceive in your womb and bear a son, and you will name him Jesus.”
The Lord God then formed a woman out of the rib that he had taken from the man. He brought her before the man. The man said, “This one is bone of my bones and flesh of my flesh. She shall be called woman because she was taken from man.” This is why a man leaves his father and his mother and joins with a wife, and the two become one flesh.
