12 When Aslan says this he is fulfilling the satisfaction theory, while explaining it. He tells Lucy that he knew what he was doing and that he had to do it to protect Edmund so that, the prophecy of Edmund, Peter, Susan, and Lucy saving Narnia could come true. .
At the end after Aslan proclaims Lucy, Edmund, Peter, and Susan as queens and kings, Aslan goes off into the distance and disappears.13 This is important because it symbolizes that Aslan came back to finish fulfilling the prophecy and nothing else. Lucy however is very sad and is confused and misses Aslan. So Mr. Tumnus says to Lucy "after all, he is not a tame lion",14 trying to explain to Lucy that Aslan only comes when he is needed and leaves when his work is done. This is also implied when Aslan tells Peter that "it is finished" after Aslan kills the White Witch.15 When Aslan also says "it is finished" he is referring to the prophecy in which the evil will no longer rein in Narnia.16 Which is how Aslan relates to the Satisfaction theory. .
In C.S. Lewis's novel The Lion, the Witch and the Wardrobe, Peter, Susan, Lucy, and Edmund's journey through Narnia is much more than just an imagined children's story. The author uses characters, particularly Aslan, to symbolize biblical themes and events. Lewis's book has been turned into a film titled, The Chronicles of Narnia: The Lion, the Witch and the Wardrobe. The movie illustrates Aslan as a Christ figure, particularly in keeping with the Ransom Theory of Atonement upon which Lewis relied in creating his metaphorical Christ figure. In order to value Aslan as a Christ figure, the Ransom Theory must be carefully clarified and understood. This theory was developed by the church father Origen (A.D. 185-254) and holds that "Satan held people captive as a victor in war. This theory, which was also held by Augustine, advocated that because Satan held people captive, a ransom had to be paid, not to God, but to Satan.
