I have often wondered over the judicial "tyranny" that we are now seeing in our court system. Judges don't make law, they only interpret the law. But isn't all law interpreted law? Doesn't the real power then lie with the judges? What good is a code that no one uses to decide cases?
I find it interesting that Israel had no legislative branch of government. They had a judicial branch (the elders of the gates) and an executive branch (the king). I'm using these terms more analogically, but it still works. The law was given by God and need neither be added to or taken away from. Even in situations that required a change of law, i.e., the transition from tabernacle to temple, these situations were done at God's direction and so he in a sense was the one changing the law. But even then it wasn't really a change, but a recontextualization. For example, the tabernacle to the temple would change things like location and music. The change is fully consistent with the previous laws. Now if the law had changed to something along the lines of no more sacrifices (by law, not exile), then that would be a contradiction in the change of the law.
It is possible to deduce by good and necessary consequence a decision for any modern case heard today strictly from the Bible without adding or subtracting to God's specially revealed will. And all these decisions would be are precedents,but not laws themeselves. So what is the point of a legislative branch then anyways? It seems that it would serve no purpose in a consciously biblically based governement.
