I believe there is an implicit suggestion in Plato, Aristotle, Spinoza, Leibniz, Kant, and Hegel that sound theology must include extensive concern with a universally accessible common ground of ethics understood by means of reason with no appeal to external authority.
My own view is that the highest form of faith is intransitive. It could not have articles. It is not a belief in some propositions, but a pure affective attitude and way of being and doing. Anything else is just a way to get to that, if it is a way to anything at all. This would be somewhat akin to traditional negative theology.
