My buddy John's got a great post on God 'n Country conflation, perhaps the most pernicious heresy in the contemporary American Church.
Among many other salient points, he says:
In the scriptures, I’m commanded to love a lot of things: my God, my neighbor, my wife, my enemy…I’m never commanded to love my country. In fact, if “loving my country” means that I demonstrate preference to someone based on their ethnicity, their nationality or, for instance, their loyalty to America’s foreign policies, I think I’ve pretty much undermined a very important aspect of Jesus’ mission on this earth — to make his temple a “house of prayer for all nations” and ours, to “make disciples of all nations.” And when I’m willing to value American lives over, say, Iranian lives or when I’m willing to promote America’s economic interests over the interests of the world’s poor simply because I’m American I may actually demonstrate my infidelity to the only Kingdom worthy of my allegiance.
This is dangerous thinking that will get anybody in trouble, but he can perhaps alleviate the threat by wearing a flag lapel pin. In the meantime, I'm surely glad I get to hang out with people who think this way.
