well, i'll admit that orthodox and heretical aren't strictly antonymous, but at least in historical use, 'orthodox' (big-o or no) refers to "adherence to accepted creeds" https://en.wikipedia.org/wiki/Orthodoxy https://en.wikipedia.org/wiki/Orthodoxy By contrast, there are few concepts more "heretical" (in the literal/etymological sense of the word) than "sola scriptura," i.e., to "become a church unto oneself." It is precisely this implicitly heretical "sola scriptura" preoccupation (and with it, such anxiety to prove the veracity of the physical texts themselves!) that contradicts the very concept of orthodoxy. Sitting in a chair is either a) not an act of faith or b) the word faith itself designates nothing at all.
