This conclusion presents some closing thoughts on the key concepts discussed in the preceding chapters of this book. The book drew attention also to the possibility that such key Christian elements such as baptism and belief in the pre-existence of Christ are later rather than earlier and that this is an important factor in the process of dating the New Testament documents. It urges the readers to consider the possibility that the Pauline letters were interpolated in the course of the first century CE, with all the consequences that this theory has for the perception of Paul at that time. It closes by emphasizing that this process of historical discernment is essential to the business of Christian faith. Scholars who must be reconsidered in this task include Semler, Schrader, Baur and the Tubingen School, Schwegler, Volkmar, Weisse, Hilgenfeld, Holtzmann, Scholten, Volter, Martineau and Barnikol.
