What to read after God and Mystery in Words?

In God and Mystery in Words David Brown uses the way in which poetry and drama have in the past opened people to the possibility of religious experience as a launch pad for advocating less wooden approaches to Christian worship today. So far from encouraging imagination and exploration, hymns and sermons now more commonly merely consolidate belief. Again, contemporary liturgy in both its music and its ceremonial fails to take seriously either current dramatic theory or thesociology of ritual. Yet this was not always so. Poetry and drama, Brown suggests, grew out of religion, and therefore that creative potential needs to be rediscovered by religion.
