text: C S Lewis wrote an interesting essay, "Meditation on the Third Commandment", in which he says that a specifically Christian political party would be a bad idea. He gives two reasons: First, that even among Christians who want a state run on Christian principles, there are genuine differences in how to bring this about, so no single party could claim to represent all Christians. Second, there will inevitably come a point where any such party must choose between power or Christian principles.
