Allegory aside, Paul still referred to what was written in the book of Genesis as the law. This is indisputable.
What about what Jesus said here?
Mar 10:2
And the Pharisees came to him, and asked him, Is it lawful for a man to put away his wife? tempting him.
Mar 10:3
And he answered and said unto them, What did Moses command you?
Mar 10:4
And they said, Moses suffered to write a bill of divorcement, and to put her away.
Mar 10:5
And Jesus answered and said unto them, For the hardness of your heart he wrote you this precept.
Mar 10:6
But from the beginning of the creation God made them male and female.
Mar 10:7
For this cause shall a man leave his father and mother, and cleave to his wife;
Mar 10:8
And they twain shall be one flesh: so then they are no more twain, but one flesh.
Mar 10:9
What therefore God hath joined together, let not man put asunder.
Jesus was asked if it was lawful for a man to put away his wife. He initially responded by asking his questioners what Moses commanded them. They, in turn, quoted what Moses had written in the 24th chapter of the book of Deuteronomy, but this was not the answer that Jesus was looking for. He, while answering the question of whether or not it was lawful for a man to put away his wife, quoted what Moses had written in Genesis 2:24. In other words, he regarded what Moses had written there as being part of the law or as being a command in relation to whether or not it was lawful for a man to put away his wife.
