This detailed yet eminently readable description of Paul's life clearly shows that all sources converge to present a pioneer life: adventurous, unpredictable, nonlinear, full of risks. An analysis of Paul's place in the development of the Christian church shows that Paul was not a marginal figure, operating out of reaction. He was instead a driven pioneer for a Christianity that is aware of Christ's kingship, and that realizes it is not a new religion but the fulfillment of the messianic promises made to Abraham. Thus Paul was above all the pioneer for the Messiah, Jesus Christ.
