Submission and Justice

What do preachers usually cite as evidence that the Bible says we should submit to (worldly) authority?  Generally it is the first few verses of Chapter 13 in the Letter to the Romans, and the several verses in the middle of Chapter 2 of the First Letter of Peter. That is about it.  Out of more than one thousand chapters in the Bible, from Genesis in the Old Testament to Revelations in the New Testament, parts of 2 chapters.  Now, if the authority’s orders are just, surely there is no legitimate reason not to submit to them.  What if they are unjust?  Should we still submit?  

What what does submit really mean?  Should we follow orders that we know are unjust?  That seems to be overridden by other verses in the Bible, where it says we should submit to God rather than man when they are in conflict.  Does that we should keep silent when the authorities do something that is unjust?  Perhaps we shouldn’t cheer and support unjust orders, even if we dare not oppose them?  

Normally, when we care about something deeply, we keep thinking about it, perhaps talking about it often.  We think about different aspects of it, considering it from different perspectives.  

How often does the Bible talk about justice? Chastising kings, priests, leaders, people in power, for perverting justice, oppressing orphans and widows, exploiting the poor, …?  That we should love justice, submit to God’s rather than men’s orders, help the poor,  give justice to the weak and the fatherless, maintain the right of the afflicted and the destitute, correct oppression, plead the widow’s cause, be willing to suffer for righteousness’ sake, …?  Everywhere we look.  Again ad again.  

If the Bible keeps talking about something, surely it must be important?  Sin, repentance and salvation - they are everywhere. And lo and behold, they are supremely, existentially  important.  

Now, teachings about justice is also many times more prevalent than teachings on submission to earthly authority.  Surely it makes sense to be more concerned about justice -  caring about it, seeking it, keeping it, helping to preserve it - rather than submitting to an authority bent on perverting it?
