It's weird to see myself quoted, but at least it's in this kind of context! I have heard a lot of discussion of Romans 13 in Christian anarchist and libertarian circles. Taking it in context of the surrounding chapters matters. So does delving into the Greek and exploring translation disputes. Of course, merely being a Christian has been "illegal" in various places for the past 2,000 years, so we all know legality has no inherent or divinely-granted authority on that basis alone.
