Philo also paints an idealized picture of the patriarchs. He states that they embodied the law and intuitively obeyed the Torah before it was written by Moses. In short, the patriarchs lived according to true virtue since the written law codified what was known to be both true and virtuous. In his concluding statements on Abraham, Philo writes that the patriarch "obeyed the law . . . himself a law and an unwritten statute." (71; citing Philo, On Abraham 276)
Joslin also cites an article by John W. Martens ("Philo and the 'Higher' Law." Society of Biblical Literature 1991 Seminar Papers 30 : 309–22). My question: Is anyone aware of anyone bringing this Philonic evidence to bear on Paul's (nearly) contemporary argument in Rom 2.14–15 regarding the gentiles "being a law for themselves" [ἑαυτοῖς εἰσιν νόμος; heautois eisin nomos]? Is anyone out there familiar with Martens's work?
