Against the Documentary Hypothesis

It is not perhaps as well-known as it should be that Geerhardus Vos published a treatise called The Mosaic Origin of the Pentateuchal Codes. In this volume, he has some wise words about the supposed criteria used to “prove” disparate sources:

What the critics in reality do by this method, is just by a dexterous but suspicious movement to turn in their favor what is in fact against them. That an Elohistic phrase all at once makes its appearance in the midst of a purely Jehovistic environment, is a most perplexing difficulty, which cannot be relieved by declaring it the result of a variety of hands which have been at work upon the composition of the Pentateuch. For it is a sound critical axiom, that diversity of style and diction can only be verified by a comparison of lengthy passages, whose usus loquendi is exclusive. Isolated exceptional cases turn back upon the theory, and prove exactly the opposite; viz., that the criteria intermingle, which is tantamount to saying that they are no criteria at all (p. 29).
