Transtheistic

1952, Paul Tillich, The Courage to Be, Yale University Press, Stoicism in this sense is a basic religious attitude, whether it appears in theistic, atheistic, or transtheistic forms.

1953, Heinrich Robert Zimmer (auth.), Joseph Campbell (ed.), Philosophies of India, page 182, […] the Tirthankaras have passed beyond the godly governors of the natural order. Jainism, that is to say, is not atheistic; it is transtheistic.
