This essay provides an assessment of the christological analogy for scripture, particularly for its usefulness in aid of a theological ontology of scripture. This analogy implies that scripture has something like ‘two natures’ – human and divine – like Jesus Christ has two natures. I argue that assessment of the analogy has been impaired by a lack of clarity in its application. On the one hand, the ambiguity relates to a tendency to apply the analogy for the (modernist) purposes of securing epistemic authority. On the other hand, I show that there are in fact three distinct forms of the analogy, each implying different things about the ‘twoness’ of scripture as well as its unity. After outlining the three forms of the analogy, I critically assess the unity they ascribe to scripture by means of the analogy.
