As I've been preparing for Pentecost this week, it has struck me that almost everything I read about the Holy Spirit is 'functional' - about the work and purpose of the third person of the Trinity.  Which is not everso helpful when I am working with three of the symbols/metaphors each of which convey something of the mystery of this aspect of the divine.

My ideas have yet to coalesce in to anything coherent... I have two lines of thought neither of which quite works but hopefully between now and Sunday things will fall into place.  Given that the two strands of thought relate to ancient classical philosophy on the one hand and the legend of a coat of arms on the other, getting to a common end point is not going to be trivial!
