text: You might want to consider the notion of "non-duality"  that is being discussed amongst contemplative Catholics/Christians. Non-duality is derived from Advaita philosophy (Hinduism).  I know, I know, it's not "Christian" or "Catholic" but Jesus talked about "truth" not just coming from Judeans, but from Samaritians and Gentiles as well.  What nondaulity empahsizes is the notion of "not two.... but not one."  It is a paradox which could generate understandings of a triune God, christology, but more importantly, ourselves, even physics in our universe.  It offers a creative tension between diversity (difference) and unity.  I'm more interested in news ways of understanding, not so much old arguments going back to Chalcedon (they don't go anywhere except divide people).
