People involved in politics tend to be weird. Christians also have a tendency toward oddness. I feel I have a licence to say that as someone who is both of those things.
So I have to confess the prospect of a whole weekend with over 100 people who are both Christians and involved in politics didn't thrill me. I anticipated it would be full of intense discussions and fractious arguments from people in different parties who couldn't understand how someone could be both a Christian and a Tory or a Christian and a leftie.
