There you go again, posing good questions! Of course, by now I should know better than to drop a loaded term into a sentence. Your sharp eyes miss nothing!
Before I try to answer the question you pose at the end of your post, I think it best to address the matter of "literal" and "myth." "Myth," to my way of thinking, is a story that captures a key truth or insight into reality and/or human nature. Scientific reality has to do with theories which are capable of being verified in some manner, not just once but repeatedly. Both myth and science deal with truth, so to speak. Unfortunately, we do not yet know how or if the two methods and their conclusions can be unified. To use an analogy, we're in a quandary similar to that faced by modern physics when it attempts to create a unified theory of everything.
The resurrection of Jesus, at the very least, is one of the great myths. Taken as metaphor or parable, it provides many a modern Christian with insights and motivation enough to sustain viable faith. Naturally, as myth the entire matter falls outside the scope of science.
The same is true, if the resurrection was a one-time event. Whether "myth" or "fact," the scientific method is not designed to investigate or assess the resurrection.
So...when all is said and done, one's approach to the resurrection boils down to individual decision.
My personal decision is to accept the resurrection as a unique event. With that as my starting point, I see the resurrection as God's validation of Jesus (his teachings, actions, way of life, etc.), hence my use of the term "hallowed." To use theological language, all the "powers" could not kill the way of God, stuff it into the grave, and make it stay there. The way of agape love triumphs, when all is said and done. As Aslan once said, this is "deep magic," and the witch does not understand it. Winters come, but they can not hold forever. Now, I'm slipping into literary talk, which is to say drawing on the resource of various sub-created myths, all of which spring from the story of the resurrection.
Would it make a difference to me if the resurrection could be proven beyond doubt to be nothing more than a delusion, a hoax, or a mistake? I suppose the honest answer is: "I don't know." I doubt that it would, mostly because the power of the story long ago gripped my imagination and began to shape my living. I choose to think it would continue to do so.
