I think distinguishing an actual, historical event from a mythological event is important, because it tells me whether I should use the literary present tense or the historical past tense. There is just one problem. How do I tell the difference between what is real and what is legendary? What if a story has some teensy-weensy grain of truth in it but the overall story sounds like a mythological folktale, such as Beowulf? Now what? Do I assume everything to be mythological, or do I assume that everything in the Bible actually, historically, really happened in a literary or literal sort of way? Or maybe this is one of those things that needs to be judged on a case-by-case basis?
Historical tense: Jesus resurrected.
Literary present tense: Jesus is resurrected.
I think it may be safer to assume that all stories in the Bible are mythological. Making historical claims is too iffy. Plus, this website is really a secular website, hosted by a secular company, so it may be best to avoid explicit or implicit doctrinal presuppositions.
