According to Chris Keith, an alternative to the search for a historical Jesus "posits a historical Jesus who is ultimately unattainable, but can be hypothesized on the basis of the interpretations of the early Christians, and as part of a larger process of accounting for how and why early Christians came to view Jesus in the ways that they did". According to Keith, "these two models are methodologically and epistemologically incompatible", calling into question the methods and aim of the first model.
