‘Paul and his letters’ asks whether Paul's historical importance is as great as his canonical presence suggests. His letters formed the heart of the collection that would eventually become the canon of the New Testament. Was he a religious genius who created, out of his personal experience, a Christ cult that was alien to the preaching of Jesus? Or was he a faithful interpreter of a movement, which he joined after having persecuted it? His letters show that Paul knew and used traditions that preceded him. However, he was thinker, and he gave his distinctive stamp to these traditions.
