Were the other temporary commands ever reversed? If so, when and for what reason?
There was no such thing as divorce prior to Moses.
Granted, there was no explicit command from God against divorce but the permanent and indissoluble union of one man and one woman has a very good basis in scripture. Certainly the permanent union of one man and one woman is consistent with the natural order of things, consistent with God’s design. Moses allowed divorce however, because mankind had become so depraved that men were killing their wives to get out of marriage. Divorce was a temporary fix for an out of control situation.
Jesus restored marriage to the way it was “in the beginning.”
And Pharisees came up to him and tested him by asking, “Is it lawful to divorce one’s wife for any cause?” He answered, "Have you not read that he who made them from the beginning 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. What therefore God has joined together, let not man put asunder." They said to him, “Why then did Moses command one to give a certificate of divorce, and to put her away?” He said to them, “For your hardness of heart Moses allowed you to divorce your wives, but from the beginning it was not so. And I say to you: whoever divorces his wife, except for unchastity, and marries another, commits adultery.” (Matthew 19:3-9)
The “hardness of heart” was mans’ unwillingness to forgive and his willingness to kill to get out of a marriage. Jesus takes the minds of his audience back to the opening verses of the Bible - in the beginning - and reorders things rightly. He restores marriage to the way it was in the beginning - one man and one woman in a permanent, life affirming relationship, where the inner workings of the Trinity are mirrored in the interaction between father, mother and children.
Slavery too. People get all upset over laws about how to treat slaves in the Old Testament, believing them to be approval of slavery. Laws about slavery not an approval of slavery but rather a first attempt to control what had become an out of control situation. It was a temporary fix until Jesus came to “restore all things.”
Drinking blood too. Most people don’t realize that Adam and Eve were not given animals to eat in the garden but only plants. Flesh was given to man after Noah and the flood. Man then became so depraved that they started eating each other, drinking each others blood, and drinking animal blood in pagan ceremonies. Drinking blood was forbidden therefor by Moses, as a temporary fix, to prevent wonton behavior, until Christ came so that we could drink his blood.
There are probably lots more examples. Moses “permitted” many things which are contrary to God’s design, if not contrary to his explicit command. Moses provided guard rails and safety nets on these behaviors until Christ came to set things right, to restore order to creation, and to remake all things new.
And he who sat upon the throne said, “Behold, I make all things new.” (Revelation 21:5)
