The doctrine of the two kingdoms, far from being a dualistic separation of the physical and the spiritual, is actually a model for bringing them together and relating them to each other. Both realms have the same King. That there are different kinds of existence we experience is self-evident. But, in the words of the Nicene Creed, the one God is “the maker of heaven and earth and of all things visible and invisible.” These are different categories, and their Creator governs them in different ways. But they are all the work of “the Father Almighty.”
