Derek R. Brown examined an issue that was often overlooked in research on the New Testament - the references to the figure of Satan in the undisputed letters of Paul. He claims that the references to Satan can be best understood when viewed in terms of apocalyptic theology of Paul, his apostles dignity and caring for his churches. By these two interpretation categories - as well as the investigation of different representations "Satan" in the Hebrew Bible and the Jewish traditions from the Second Temple period - draws on the analysis, the author concludes that Paul Satan in his letters basically as the represents apocalyptic counterparties of his apostolic work (κόπος) opposes that what is crucial, including its parishes. It is argued that Paul does so because he believes that the success of his apostolate is crucial for spreading the Gospel at a crucial point of salvation history.
