The Ultimate Being must be both one and many for Him to be a communicable being. For instance, without unity, there would cease to be any one thing that was Ultimate. Without diversity, there would cease to be any formal differentiation within God, which would hinder God from distinguishing between things and communicating accordingly. Thus, only the trinitarian God of the Bible, who is both one and many, meets the necessary preconditions for divine communication.
Not really buying this. I don't see how it is neccessary that God be trinitarian for him to be able to distringruish between himself and creation, and from being able to communicate with his creation. I'm not trinitarian, but I communicate with things and differentiate between self and non-self, why couldn't God?
