Chapter 8 addressed the violence in the Old Testament and how we reconcile that with Christian nonviolence.
Chapter 9 deals with a single passage that gets abused quite a bit: “Let Every Soul be Subject”. Lee Camp tackles what this passage means in context, instead of in the absurd isolation in which it is often quoted, violently ripped from God’s word in order to serve agendas of violence.
If you read the entire passage of Romans 13, you realize that this one phrase was never meant to be a military mantra. We are to “present [our] bodies as living sacrifices” before God, and commanded not to “conform to the age” (often translated “the world”). Since we are a new creation, we live according to a new age. So whatever authorities we are under, they’re not ours.
