One of the subjects that is all the rage now in NT studies is rhetorical criticism. It is frequently proposed that some rather elaborate rhetorical structures can be found in Paul's letters or in other epistles in the NT. I have been wondering how much research has been carried out on the relationship between this and textual criticism.
Often the proposals for rhetorical units do not correspond to units indicated in the earliest manuscripts. Now that could be because the early scribes simply failed to recognise the units, but is there a case for saying that the widespread failure of early scribes to recognise rhetorical structures which are claimed to be widespread in the first century actually undermines the view that the structures themselves were so widespread? What bibliography could one recommend?
