"What we find in mainstream biblical scholarship is a major bias against the recognition of literary dependencies within the extant texts. So what we see in mainstream biblical scholarship is a major reliance on imagined “lost sources” to explain the similarities between texts. As we see here, biblical scholarship is full of imagined lost sources, both oral and written, used to explain the commonalities across the texts of the New Testament. Yet in reality, virtually all of these relations are far better explained as dependencies among the extant texts. The problem with recognizing dependencies among the extant texts, however, is that everyone recognizes that none of the extant material comes from direct witnesses to Jesus. It is recognized that none of the extant material represents primary sources, and thus imagined potential primary sources are the favored explanation for textual similarities. Thus, what we see in mainstream biblical scholarship is that not only do biblical scholars jump to the conclusion that textual similarities must be the product of the use of a common lost source, but also that the lost source itself is likely an “original” primary source. This is the rational behind Q, and the rational behind claims like those that we see Bauckham making here."
