As he explores how Paul's theology relates to that of the broader early church, Sumney identifies where in the Christian tradition distinctive theological claims about Christ, his death, the nature of salvation, and eschatology first seem to appear. Without diminishing significant differences, Sumney describes what common traditions and beliefs various branches of the early church shared and compares them to Paul's thought. Sumney interacts directly with arguments made by those who claim Paul as the inventor of Christianity and approaches the questions raised by that claim in a fresh way.
