I am never comfortable when I see Christians ardently devoted to America, or to any government of this world in which they are in allegiance to. Of course I have to remember I was raised Anabaptist, and in recent years have returned largely to those roots.
While C.S. Lewis defends a kind of nationalism to be embraced by Christians, I'm more on board with Dietrich Bonhoeffer who seemed to resound against such a nationalism, at least the kind he saw Christians accept and even embrace in Germany during the Nazi rule. Bonhoeffer's critique was based on Jesus' words in the Sermon on the Mount. Bonhoeffer's understanding of the application of those words was in large part the basis for his critique.
It's not just about Christian pacifism, or nonresistance. It's -more to the point- to what and to whom we belong. God is our King. And we in Jesus are part of the kingdom of God made known and spelled out in the good news/gospel of Jesus.
So it's an identity issue. And then the question comes just how much, or to what extent we can be identified with our various nations, as the new Israel scattered throughout the earth. That is not an easy question, and both individual Christians, as well as churches will vary on their answers, or practice, even within the peace churches.
I for one think Christians can participate in any area of government, unless, obviously, such participation is in violation of God's will. So this makes it hard for me to envision a Christian being Commander in Chief of the United States military, or president. Of course Christians will not agree exactly on where to draw the lines on this.
This view is not a popular one in the world, or among Christians, and I rather doubt it will ever be. It's not without its problems and perplexities. But neither is the alternative.
Any thoughts any would like to share here?
