Over at Eerdword, I have a post introducing and explaining the rationale for my new book An Anomalous Jew: Paul among Jews, Greeks, and Romans (Grand Rapids, MI: Eerdmans, 2016).
In sum, Paul was a socio-religious anomaly. He appeared on the scene of the Greco-Roman world like a sudden yet small ripple moving upon the waters of a still river. He goes mostly unnoticed in his own time, and yet by the time the ripple reaches the shores of the modern age, it has become a tsunami. Paul’s anomaly, offensive as it was to Jews and odd as it was to Greeks, became the Gentile Christianity that eventually swallowed up the Roman Empire and even to this day casts its shadow upon the religious landscape of the world. Not bad for a Jewish tent maker from Tarsus.
