2006 0-7734-5901-4 The combined effect of observations made by John Owen (Puritan Vice-chancellor of Oxford University) in tracts published in 1655 and 1679 was that Quaker theology renewed aspects of Gnosticism, a theology interpreted by patristic commentators as Christian heresy. This monograph argues that George Fox’s theological message (and in particular, his interpretation of the concept of revelatory Light) incorporated a remarkably similar soteriology and realised eschatology to that found in Valentinian Christian Gnosticism.
