Hey Tom,
Just to get you "in the ballpark," I'm an amil shading toward postmil, but at the core I am a biblical theologian and those "labels" are very general. I've been hanging with postmils, but I don't accept the viewpoint entirely. Nevertheless, I daily pray for God's Kingdom to be implemented here on earth and I work toward that end while I wait (impatiently) for the second advent.
There are a number of "alternative" understandings of Romans 13. I don't claim to have 100% exegetical clarity on every detail in the chapter, but I am sure that the "standard" interpretation is wrong-headed. It just doesn't fit the overall teaching of scripture. This article is my best shot at explaining it thus far, or at least countering the prevailing view:
As I've been working my way through the New Testament in Greek, I've become more and more persuaded that the book is principally a handbook for God's new/preferred form of human government. And that form is humanly decentralized, local congregations each directly reporting to Jesus as Chief Shepherd.
To "see" this requires looking at the NT through a different pair of glasses, as I've tried to describe in this article:

I'm not asking you to believe/accept this yet; just consider the possibility, and please do argue against it, particularly if you bring scriptural ammo to bear.
Thanks for reading my stuff and discussing.
