From the intro: Perhaps as much as any other election, Christians have a vested interest in this one. The Bible has not changed, and the doctrine of the two kingdoms remains the same, but culturally and societally life for the American Christian, who holds dual citizenship in the temporal and spiritual kingdoms, has taken on a different sense and feel. It is a salutary thing, then, to review what Scripture and the Lutheran Confessions have to say in this regard and to wrestle with how we apply Lutheran principles to new circumstances.
