Christ’s spiritual kingdom and civil jurisdiction are things completely distinct. Yet this distinction does not lead us to consider the whole nature of government a thing polluted, which has nothing to do with Christian men. That is what, indeed, certain fanatics who delight in unbridled license shout and boast… But as we have just now pointed out that this kind of government is distinct from that spiritual and inward Kingdom of Christ, so we know that they are not at variance.
– John Calvin
