I do think there is a universal pattern of a threefold truth, although our traditional trinitarian doctrine is hobbled because it is expressed in a now widely rejected substance philosophy. Still, each tradition has somehow to concretize its ultimate meaning in concrete terms, lest God become too distant to matter. Buddhist have their three Jewels of Buddha, Dharma, and Sangha. Ones school teaches a threefold truth of emptiness, convention, and the middle path, which can be used to speak of the apophatic Father, the embodied, convention Christ, as the Spirit path that enables people to abide in the non-duality of Father and Son. By now there must be literally hundreds of books on rethinking trinitarian doctrine, for most realize the vast disconnect between the ancient Greek philosophic forms of substance, essence, and relation, and today's philosophies. The ancient creeds are not wrong. They are just ancient.
