"Sola scriptura" may be contrasted with "prima scriptura", which holds that, besides canonical scripture, there are other guides for what a believer should believe, and how he or she should live. Examples of this include the general revelation in creation, traditions, charismatic gifts, mystical insight, angelic visitations, conscience, common sense, the views of experts, the spirit of the times or something else. "Prima scriptura" suggests that ways of knowing or understanding God and his will, that do not originate from canonized scripture, are in a second place, perhaps helpful in interpreting that scripture, but testable by the canon and correctable by it, if they seem to contradict the scriptures.
