When I was a wee child of < REDACTED BY BIRTHDAY FAIRIES >, a certain movie trailer for a certain movie that's based on a certain-book-trilogy-that-I-solidly-main
The point is that I was a very odd child, and had a very strong sense of myth at a young age. I read bits and pieces of myths from Hawthorne's Wonder Book, Lang's Fairy Stories, and then some miniature Hans Christian Anderson collections. For a long time, I was confounded as to why fairytales as frequently bloody and war-ridden as these would be transformed into as shiny, squeaky-clean things as the Disney adaptations.
As it was, my love of fairytales progressed into a love of fantasy because, when PROPERLY done, I interpret it to really be just modern fairytales, though often sans fairies. But I still couldn't figure out why on earth I preferred them so greatly to other forms of entertainment.
Then, one evening, I was looking over some artwork online detailing the life of Christ. There was one particular piece, though I don't remember who painted it, that showed in excruciating detail the scourging at the pillar. I winced when I looked at it--but in that moment, something clicked. What if terrible (and often bloody) things happen to people in fairytales as an outward sign of inner self-sacrifice in much the same way that Christ's death on the cross was a sign of his love for us?
When one examines fairytales in depth, especially those that are romantic in one way or another, there's a great deal of suffering and pain that the hero and heroine often go through. This isn't gratuitous suffering, though--it serves to solidify and ground the love that the hero/heroine feels for the other in a very real, human way. Although it may well seem morbid, this is a tactic that originates in our own Christian tradition--when God sent his Son to redeem the world in the ultimate act of love, however painful and bloody it may have been. We don't fight to protect something that we hate, after all; and every fairytale involves fighting.
In consequence, because this ultimate act of love is so firmly rooted in our tradition, it becomes natural that it should filter down through our myths and folklore. In some ways, the redemption of the human race through Christ is the best story in the world--it has all the elements of a beautiful story, with the tremendous advantage that it's true. All stories, we would hope, would reflect the basic truth of God's love and the ultimate triumph of light over darkness--maybe through shadows and mirrors, but it's there all the same. We may think that novel such-and-such is just about a mythical war of a mythical land between a mythic people and the powers of evil--but it's still reflecting the basic truth that God's goodness will always overcome the powers of evil, no matter how hard and impossible it might seem.
I love happy endings.
