Theology is born of wonder. We see the sun and ask: What light illumines this light? We read of a bush that burns but is not consumed and wonder: What fire burns without need for fuel? Wonder before the realities presented to us by the Book of Nature and the Book of Scripture leads us to wonder about those realities. The quest for understanding, which drives all intellectual disciplines, drives the discipline of theology as well.
Yet theology’s quest for understanding is tempered by several considerations. God is not a body in space that can be measured. Nor is he a member of a class that can be analyzed in terms of genus and species. In scriptural idiom, “the King of ages” is “invisible.” God transcends both our physical and our intellectual capacities of perception. “The blessed and only Sovereign” is one “whom no one has ever seen or can see.”
