 Opponents of this sort of mysterianism object to it as misdirection, special pleading, neglect of common sense, or even deliberate obfuscation. They emphasize that trinitarian theories are human constructs, and a desideratum of any theory is clarity. We literally can’t believe what is expressed in trinitarian language, if we don’t grasp the meaning of it, and to the extent that we don’t understand a doctrine, it can’t guide our other theological beliefs, our actions, or our worship (Cartwright 1987; Dixon 2003, 125–31; Nye 1691b, 47; Tuggy 2003a, 176–80). Negative mysterians reply that it is well-grounded in tradition, and that those who are not naively overconfident in human reason expect some unclarity in the content of this doctrine.
