From Light from the Gentiles – Hellenistic Philosophy and Early Christianity:
During the last century, NT scholars have shown that many aspects of Paul’s life and letters are illuminated when they are examined in light of Greco-Roman culture. There is no longer any doubt that Paul was thoroughly familiar with the teaching, methods of operation, and style of argumentation of the philosophers of the period, all of which he adopted and | adapted to his own purposes. This is not to argue that he was a technical philosopher; neither were his philosophical contemporaries. The philosophers with whom Paul should be compared were not metaphysicians who specialized in systematizing abstractions, but, like Paul, were preachers and teachers who saw their main goal to be the reformation of the lives of people they encountered in a variety of contexts, ranging from the imperial court and the salons of the rich to the street corners.
