Book excerpt: "A theology which comes pre-packaged, and in which there are no loose ends, is not true to life nor can it adequately reflect the richness of the Gospel." Why are churches struggling to maintain credibility in a culture in which there are more spiritual seekers than at any time in living memory? John Drane believes that churches have become stereotyped structures, offering uninventive formulaic worship to a dwindling minority. But there are exciting opportunities for growth, he argues, if only churches will rediscover their own creativity and flexibility. If only they will offer something more nourishing for post-modern spiritual appetites than the equivalent of fast food.
