I remember the little church we would frequent had two flags: one American, one Christian. One Fourth of July weekend, I clearly remember singing the National Anthem and the Battle Hymn of the Republic. Church and State were partners in those days, and the patriotism seemed to go hand-in-hand with Christianity. And, in many churches today, this is still the case. But should it be? Some Christians believe quite strongly that we cannot be patriotic. With our citizenship in Heaven (Phil. 3:20) shouldn't be skip the fireworks on the Fourth and instead long for the country that is coming — the one without corruption, without injustice. The one ruled by the One great King?

Not Blind Patriotism

Both of these views are right, and both are wrong. Blind patriotism is clearly wrong. And, many American Christians are blindly patriotic. Believing only in the Christian America origins of our nation, this view utterly ignores the weeds of injustice which have grown up along the good stalk of the puritanical vision. The same weeds that today seem to be choking it out altogether in many quarters. Indeed, our citizenship is in Heaven, so we can never be blindly patriotic.

Worst of all, though, blind patriotism always devolves into a kind of syncretism. It muddies the clear, fresh water of the gospel, trading it for the mixed, brackish, and unhealthy false gospel of "America first."

Not Separate Kingdoms

So why not separate entirely? Why would Christians even bother engaging in an American that is wrought with so many problems? Well, the simple answer is, the Bible commands us to engage the world, not retreat from it. While we're not of it, we're still in it. (Jn 17:16) The very reason that God's people remain in the world is to engage it with the gospel, so that every nation might be present before God in worship for all time. (Rev 7:9)

Tragically, those who advocate the church as a completely different kingdom than the world devolve into a sub-Christian separatism. I'm just glad Jesus wasn't a separatist.

Patriotism as Resident Aliens

The Apostle Peter gives insight into this question in his epistle. He calls the church, “elect exiles of the Dispersion” (1 Peter 1:1). Christians are chosen by God to live as exiles in another country—resident aliens. The citizenship of the Christian is in heaven, but the residence of the Christian is in his city. The allegiance of God’s people is to the King of the Kingdom of God, Jesus Christ. But God’s people must love their city and their neighbors all the same. Keller notes:
