I was pointed to this article while checking out another Christian blog. It is well worth reading.
There is a Christian politics, which is to say that following Jesus must lead us to care about the political decisions, the law-making and law-enforcement, the policies of war and economics and international relations that impact people’s lives in profound ways.
But it is a politics of Jesus. When we wed a Christian politics too closely to the aims of one particular political party or to one particular political entity — e.g a particular nation! — it is not a politics of Jesus any more.
Followers of Jesus are first and last citizens of the kingdom of heaven.
