"When Jesus told the Roman governor Pontus Pilate that his kingdom was not *of* this world, he closed the door on any possibility of a worldly Christian nation or empire.
There is the peaceable kingdom of Christ and there are the warring nations of this world, and there can be no conflation of the two.” - Brian Zahnd
And that, ladies and gentlemen, is pure rubbish. It simply does not follow either logically or exegetically (and hence a non sequitur) that because Christ's kingdom is "not of this world" the door is closed to the possibility of a Christian nation. We currently live in a dialectical eschatological tension between the "already" and "not yet", and in accordance with this the possibility of a Christian nation cannot be foreclosed. One does not need to be a postmillennialist to hold this position. More importantly, when we consider all the alternatives, a Christian nation emerges as the best of all possible states.
"What *do* they teach them at these schools"?
