Consumerist readers "treat what they read only as objects for consumption, to be discarded when the end for which they were read has been achieved". Griffiths offers modern academic reading as an example:
Academic readers consume the works of others and produce their own; they are defined and given status by the body of literature they control and upon which they are accredited to give authoritative (expert) voice for proper reward; they cite and mention (rather than religiously read), and are in turn judged largely by the extent to which the works they produce (again, the industrial metaphor, the image of mass production) are cited and mentioned.As you'd guess, Griffiths' book is a jeremiad (his word) snuck in under the respectable imprint of Oxford University Press. He makes it clear that he believes consumerist reading is destructive.
Religious reading, says Griffiths, "has to do primarily with the establishment of certain relations between readers and the things they read". Religious reading treats its object with reverence, as an inexhaustible treasure house which continually yields new objects of wonder and "always precedes, exceeds, and in the end supersedes its readers". Religious readers "are seen as intrinsically capable of reading and as morally required to read". The metaphors here are not industrial, but biological, e.g., rumination, eating, digesting.
For the religious reader, the work read is an object of overpowering delight and great beauty. It can never be discarded because it can never be exhausted. It can only be reread, with reverence and ecstasy.
