Apophatic theology was one of my early drawing-in points to Orthodoxy back-in-the-day. It was the most ... logical (I guess) to me that one could best describe the indescribable by using "not" instead of "is". After all, once you have a term like uncircumscribed... and THEN you try to circumscribe... well.... and yes of course by even using a term like uncircumscribed *is circumscribing* by it being a concept... but even in the church fathers, they repeatedly (that I remember) remind the reader that, they're using the terminology as a lesser form of language as it were.... pointers to unknowable knowledge but not the knowlege itself, which is experiential in nature etc.
