Deep down I don't believe in the separation of church and state. Oh, I am against the idea of a state church or giving political preference to one religious sect or another, but it's the idea that somehow people can divorce their religious identity from their political identity that I just can't accept. That either our religion or our politics mean so little to us that we could restrict them to compartmentalized spheres in our lives seems absurd to me. I know people attempt to do it all the time, believing in the modern myth that an individual can assume an objective stance in this world, but reality is a lot more complex than that.
In Galatians 5:19-20, Paul lists the "works of the flesh," contrasting them to the "fruit of the Spirit" immediately thereafter (Gal. 5:22-23). Among the works of the flesh are hostility, quarreling, jealousy, outbursts of anger, selfish ambition, dissension, and division. Another translation puts it, "People become enemies and they fight; they become jealous, angry, and ambitious. They separate into parties and groups ... I warn you now as I have before: those who do these things will not possess the kingdom of God."
