Far from trying to undermine faith in Jesus, Spong says in his final chapter, he is trying to bring back into the Christian fold all those who have left because they cannot rationally accept the gospels as literal history. Spong's book resolves the apparent contradiction between faith and rationality by refering the gospels to their source material in the Hebrew Bible.
Interpreting the Gospels in this context leads the reader to many new conclusions about the early days of Christianity, and further opens the possibility that the real value of the Bible is not in its accuracy as a literal historic document.
