I would be remiss if I did not highlight the most beautiful and poignant scene of The Lion, the Witch and the Wardrobe.
“And now, who has won? Fool, did you think that by all this you would save the human traitor? Now I will kill you instead of him as our pact was and so the Deep Magic will be appeased. But when you are dead what will prevent me from killing him as well? And who will take him out of my hand then? Understand that you have given me Narnia forever, you have lost your own life and you have not saved his. In that knowledge, despair and die.”
If you are at all familiar with the Chronicles of Narnia, you know that these are the final words spoken by the White Witch before she slays Aslan on the Stone Table as a substitute for Edmund. Because Edmund had attempted to betray his siblings and deliver them to certain death at the hands of the White Witch, his life belonged to her. All traitors’ lives were her property.
Aslan took that punishment for Edmund. He voluntarily surrendered his life even though it seemed to be giving evil the victory. In the subsequent battle, without Aslan, the prospects would have been rather bleak for the forces of good. The Witch was a powerful sorceress, and with her magical ability to turn any living thing to stone, the battle would have been very difficult if not impossible to win.
Even with that knowledge, Aslan still willingly went to the Stone Table for the sake of one traitor. The thing is that Aslan had another piece of knowledge that the Witch did not have.
“’It means,’ said Aslan, ‘that though the Witch knew the Deep Magic, there is a magic deeper still which she did not know. Her knowledge goes back only to the dawn of time. But if she could have looked a little further back, into the stillness and the darkness before Time dawned, she would have read there a different incantation. She would have known that when a willing victim who had committed no treachery was killed in a traitor’s stead, the Table would crack and Death itself would start working backward.’”
Aslan was triumphant specifically because he was without fault. He was in a unique position to save Edmund’s life because he had committed no treachery. Only an innocent victim could pay the penalty and demolish the power of death.
The symbolism here is obvious, and even with only a cursory knowledge of both Narnia and Christianity, you would know that Aslan is representative of Jesus Christ. He died in the place of one who could not pay his own penalty, but because of his sacrifice, he triumphs over death and brings salvation to not only Edmund but also Narnia as a whole.
In battle the next day, Aslan kills the White Witch and installs the Pevensie children as kings and queens of Narnia. The wintery curse of evil had been broken, and the power of the Witch had been demolished. All was set to right through the sacrifice of a perfect victim. It is a beautiful thing in fiction, but it is even more beautiful in in reality.
