From the article:
The following five major theological problems are created when Christians tell our Magistrates that they need pay no heed to the specific Authority granted them in Romans 13: 8 - 10:
Hold on a moment, when did any of us even suggest that we tell our "Magistrates" this? You're putting words in our mouth that we never said.
And again, this line of argument continues to ignore the historical context of Romans 13. Christians had no significant influence on their government whatsoever when Romans was written; indeed, the Roman authority was already hostile to Christianity, depending on the exact dating of Romans. So Romans 13 cannot be considered only as some prescription for a democratically-elected government.
