According to a growing number of scholars, when Paul makes use of the phrase ‘peace and security’ in 1 Thess 5.3, he is alluding to a well-known slogan in Roman propaganda that summed up the benefits of the Pax Romana. While there can be no doubt that ‘peace’ played an important role in Rome's imperial ideology, it is less clear that this was the case for ‘security’, and a review of the evidence presented by the proponents of this view calls into question their conclusion that ‘peace and security’ had the character of a slogan.
