The strongest argument for non-participation has to do with a Christian’s citizenship. It’s a case I’ve made before, but I feel strongly enough about it to address it again. To be honest, I think that a true understanding of citizenship limits a lot of the nationalistic expressions and patriotic stances that I see in Christians in the United States.
For many, there almost seems to be a conflation of the Kingdom of God and the nation of the United States. (“God bless the U.S.A.” is less about God and more about the U.S. A.) What’s good for the U.S. is good for God. That attitude runs contrary to what I see in the Bible, where Christians are to live as strangers and aliens, seeking a heavenly city rather than an earthly one.
No man can serve two masters. No one serving as a soldier in the Lord’s service should be distracted by the “civilian affairs” of this world. You can’t be an ambassador of one nation and full-fledged citizen of another.
We are citizens of a nation that spans all earthly borders, includes all nations and races, speaks every earthly tongue. The good of every person on this earth is our business. The welfare of every nation on earth is our concern. Our main prayer is that we be able to lead quiet lives, able to spread the good news of God’s reign.
I don’t see how serving in the military of any one country can fit with that stance. Again, I’m in no place to condemn those who make a different choice. But I know that growing up, I never heard this teaching. I thought patriotism was a natural part of Christianity and military service a necessary part of patriotism. My aim is to help others at least recognize that they are making a choice, one that can have powerful consequences.
