Talk of the rich oppressing the right of the poor and fatherless seems similar to our conception of rights. The poor had certain enumerated rights: the return of land at Jubilee, the return of a cloak used for collateral at night, the opportunity to glean the fields, & etc.
So, does that mean that everyone had a right to impartial justice under the OT Law and a right to those social obligations the Law commands?
Also, how do rights work now that we are in the NT and as gentiles that are not bound by the Law? Perhaps the system is now a right to be under the morality and social obligations laid down by Jesus and the apostles?
If true, that would be extraordinary. All kings and politicians will have to give an account one day to their Master and God. Then, it makes sense that they will be judged as successes or failures based on how much fidelity they had to the commands of Jesus and the Spirit as rulers.
As someone with a degree in International Relations and Political Science, I know that if rights are based on the commands of God in the OT and NT, then that would mean our modern human rights regime, based on secular principles applicable to all cultures, is in error. For the simple reason, that it shirks biblical morality and biblical commands and obligations. I say that, because, if justice and rights to God are based on His moral system and His system of obligations, then any other competing idea is in fact a counterfeit. That said, it is very good to know we believe in impartial justice here in America, which seems like a major aspect of biblical rights.
