Frankly, I don't care whether faith and politics can be "reconciled." There's a huge part of Christianity -- and I could name some other religions here -- that will never be compatible with any form of democratic pluralism whatsoever. Faith just needs to step aside when it comes to politics, which should never be conducted in a way that participants can appeal to beliefs that are beyond contestation. In politics, you need to be able to convey your principles in a way that can be understood and contested by anyone, rather than by recourse to dogma.
