the Gospel corpus (plus Acts) and the epistles of Paul had long before had an established tradition. In fact, somewhere during the time frame between the writing of some of the canonical books themselves until about 40 years after the close of the canon, these two collections of texts appear to be well-established as Scripture.
Last, there are a number of reasons why even the reliance on the Q and Gnostic traditions do not constitute grounds on which to deny the gospel facts of the death and resurrection of Jesus. Several responses were given to show that, at every turn, such a thesis is strongly opposed by the data.
Therefore, it must be concluded that the recent interest on the part of some scholars in this Gnostic scenario does not threaten the historicity of the life, teachings, death, or resurrection of Jesus. The majority of critical scholars have rejected such a conclusion and we have attempted to argue that there are certainly firm grounds for doing so.
