I am and always have been agnostic on the existence of the various potrayals of God, or other deities and spirits for that matter. I don't apologize for that, it has just always seemed like the most rational position to me.
But we're not talking about the existence of the portrayals. In fact, being agnostic about the existence of the portrayals doesn't make any sense. They clearly do exist. I can't for the life of me think why you put the matter that way, but fudging springs to mind.
Isn't there a slight contradiction in saying 'who am I to speak for god?' and also saying you don't necessarily believe god exists?
To be honest, I think that is part of the reason some of us heathens here sometimes wonder what your position actually, really is, or whether your agnosticism is something of a convenience, in discussions, to allow you to avoid.....the aspects of belief in god which are in some way problematic to justify. Such as dud prophets of god.
"into every gap they put their delusion, their stopgap, which they called God". Etc. And no, I am not necessarily using that line in exactly the same way that Shakespeare, or Nietzsche, or whoever, originally used it.
