Biblical scholars generally agree that Luke’s Gospel was written at least a generation later than Paul’s first letter to the Christians at Corinth. Yet whatever the dating, and irrespective of scholarly disputes about whether “Luke,” the author of the eponymous Gospel and the Acts of the Apostles, and “Luke,” the companion of Paul mentioned in Acts and several Pauline letters, are the same person, First Corinthians and Luke-Acts are built on the same, deep theological insight: the incarnation of the Son of God, and his birth, ministry, death, and resurrection, turned the world upside-down.
