Keeping alternatives alive

"Only a crisis brings about real change. When the crisis occurs the ideas that are adopted are those which are readily available. It is part of the duty of the Church to keep alive alternative ways of thinking and living in preparation for the time when the politically impossible becomes the politically inevitable."

- Richard Chartres, Green economy possible with political will.

Do you think this is a helpful way of talking about one of the political roles of the church, as a witness to and guardian of the idea that other ways of life are possible, that repentance is the most fundamental freedom, that there is nothing inevitable about the present political landscape?
