Jesus Has an Opinion on That
Now the dictum that “Jesus is Lord, and not Caesar” requires that we go one way or the other, down into the details, and that we do so in His name. The only way to avoid that is to reject the claim that Jesus has something to say about how we govern ourselves. For as soon as you say that He does have opinions on it, then some bright fellow will ask, “Oh? What are they?” And I will say that Jesus wants us to stop spending money we don’t have, and a Christian Keynesian will say the opposite. And somebody is wrong, not only about the economics, but also about what Jesus wants.
The only alternative to this is to say that Jesus doesn’t care what the magistrate does. But if He cares, then His people will be asked how He cares, and how His care cashes out. As a minister of Christ, I don’t have the option of saying nothing.
