Most people would agree with the adage 'a picture is worth a thousand words'. But there is another side to this coin. History is full of examples of people using imagery that too often merely masquerades as Christian. Notorious examples include visual representations used in Gnostic literature, as well as in the writings of some medieval mystics, the Radical Reformers and extreme charismatics. Many of these lack valid criteria of interpretation, relying instead on subjective conviction. When it comes to the theological language we use today, we need to learn how to distinguish between the good, the bad and the unhelpful. This illuminating book will help all who read it to do just that. Book jacket.
