My personal take is that our understanding of the Creator has evolved through time from a mythical super man to an abstract entity with human ideas, and finally to what is referred to as an "unknowable essence". Human social, cultural and political evolution is promulgated by the subtle philosophical shift from age to age. As we "mature" our awareness of the deity as a "personal" God receeds further and further into oblivian. Concomitant to that is the awareness of the similarity of other culture's and religions commonality, albeit, they are described differently and manifest or reflect different biases. Ultimately we are brought to the conclusion that we are all one human family with much more in common than ever iterated by our past narrowmindedness. Our values are amazingly similar, inspite of our diversity.
We not only can tolerate diversity, we can celebrate it, be it color of skin, language, customs or cosmology.
Indeed, leaving the UU cave advances the awareness of our unity in diversity.
