Just to draw your attention to another piece of literature in which it would seem that Kephale denotes the sense of source or origin and not authority over. See Suzanne's Bookshelf. I wonder if I'll be able to write on Pauline theology without writing about this?
I certainly want to write an essay in which I redeem Paul for the way that he has been thought of by the church as someone perpetuating patriarchal culture. However, having dealt with this such a lot recently, it would be good to write instead so that I might redeem Paul in the sense of the charisms and especially his expectation that our walk in the Spirit should be an experiential thing in which speaking in tongues, for example, was just a normal part of Christian life for the edification of the believer and the church at large if occurring in an orderly way and with interpretation.
Paul was a wonderful, passionate, Spirit-filled, prayerful, suffering, charismatic, humble, egalitarian sort of chap! I'm loving learning about him, thanks to Fee and Dunn.
