This book explains:
-- tensions between Jesus and his family at the start of his ministry
-- Jesus' relationship with his father and how that can be inferred from his image of a father-God
-- emotional distancing between Jesus and his mother
-- significance of John the Baptist as mentor to Jesus
-- importance of Jesus' temptations by Satan in the wilderness in a rejection of grandiosity
-- Jesus' sexuality
These then, were components of a transition at thirty that contributed to Jesus' generative identity, and his achievement-filled ministry. Jesus' inner struggles turn out to have been related to the most urgent psychological needs of his age, and the relationship of Jewish people to their Roman conquerors.
The book concludes with an illuminating account of earlier psychological studies of Jesus by David Friedrich Strauss, Ernest Renan, Johannes Weiss, Albert Schweitzer, and Anton Boisen.
